Roughly 1.6 million freight cars are in North American service, and the railroads own a minority of them. The rest belong to lessors and shippers — which is why "who do I lease cars from" is one of the first real questions a growing rail program has to answer. Look at the side of any private car and you will see the answer stenciled on it: a reporting mark ending in X, with a prefix that names the owner. GATX, TILX, UTLX, PROX. Four marks you will see thousands of times in a yard, attached to four very different companies with very different reasons to say yes to your deal.
Lease expiring, cars sitting idle, or need cars? The Railcar Lease Renewal Desk benchmarks renewals, places idle cars on sublease and sources cars. Current market numbers are on the railcar lease rates tracker.
Lessor vs. Lessee in a Railcar Lease
In a railcar lease, the lessor is the company that owns the railcars and leases them out; GATX, TrinityRail, and Union Tank Car are the largest examples. The lessee is the shipper or other user who pays a monthly rate to use the cars without owning them.
Full-service lease vs. net lease: who handles maintenance
Under a full-service lease the lessor carries maintenance, repairs, ad valorem taxes, and usually regulatory compliance, and recovers those costs through a higher monthly rate. Under a net lease the lessee takes on maintenance and taxes in exchange for a lower rate. How running repairs and wheel sets are split varies by contract, so read the maintenance clause before comparing rates.
What a Railcar Leasing Company Actually Sells
A railcar lessor sells you the use of equipment the railroad will not furnish. That is the whole business. The carrier moves the car and bills you the freight; supplying a car that matches your commodity, your loading spout, and your unloading pit is your problem, and a lessor is the most common way to solve it.
What varies between companies is how much of the rest of the problem they take on. At one end, a full-service lessor also owns repair shops, tracks your cars' regulatory due dates, handles the mechanical department work, and pays the property taxes. At the other end, a finance-driven lessor hands you a car and an invoice and expects you to run everything else. Both are called railcar leasing companies. They are not selling the same product.
Two things a lessor does not sell, and shippers regularly assume otherwise: freight rates and rail access. Your lease has nothing to do with what the railroad charges to haul the car, and no lessor can get you served at a facility that has no track. Those are separate conversations — the first covered in our guide to how rail freight rates work, the second in our breakdown of private rail spur costs.
The Major Railcar Leasing Companies at a Glance
A handful of companies hold the large majority of the leased fleet, with a second tier of builder-lessors, investor-backed platforms, and specialists behind them. Fleet counts move with acquisitions and scrappage, so treat the figures below as orders of magnitude rather than quoted numbers.
| Company | Fleet focus | Typical structure | Best fit for |
|---|---|---|---|
| GATX (GATX) | Diversified — tank and freight cars | Full-service, multi-year | Shippers who want maintenance and compliance handled |
| TrinityRail (TILX) | Diversified, builds what it leases | Full-service, net, per-diem, sale-leaseback | New cars built to spec from one counterparty |
| Union Tank Car (UTLX / PROX) | Tank cars, builds its own | Full-service, long term | Chemical and refined-product shippers |
| GABX (ex-Wells Fargo Rail, managed by GATX) | Diversified freight and tank | Net and full-service | Larger fleets, finance-led deals |
| AITX (ex-SMBC Rail / ARL, ex-Andersons) | Diversified — covered hoppers, tank, flats | Full-service and net | Long-term commitments, sale-leasebacks |
| First Citizens Rail (ex-CIT Rail) | Tank and freight cars | Full-service and net | Mid-size fleets wanting a bank counterparty |
| Greenbrier (GBX Leasing) | Newer builds, plus managed fleets | Leases plus fleet management | New equipment with outsourced administration |
| Investor-backed platforms | Opportunistic, mixed | Net leases, sale-leasebacks | Shippers monetizing an owned fleet |
| Mid-size lessors and dealers | Used cars, niche types | Short term, per-diem, lease-to-own | Small fleets, seasonal peaks, fast starts |
One consolidation note before you build a bid list. This industry has been consolidating for a decade, and the names on older lists are wrong. GE Railcar Services became Wells Fargo Rail, and that fleet now sits with GATX and Brookfield under the GABX mark. American Railcar Leasing went to SMBC, and the SMBC and Andersons fleets are now AITX. CIT Rail is First Citizens Rail. Mitsui Rail Capital is Modern Rail Capital, and CAI Rail is PNW Railcars. Confirm current ownership before you assume two names on your list are two independent bids. Sending the same RFQ to two desks that answer to one balance sheet is not competitive tension; it is one quote with extra steps.
Railcar Leasing Companies by Car Type: The Longer List
The majors are the right first call for a real fleet on a real term. For anything else, here is the second tier, which most "top lessors" lists leave out. Each name links to the company's own leasing page. Fleet mix changes, so treat the car types as a starting point for the call, not a promise that a car is sitting idle today. Steel Wheel Logistics has no ownership interest in any of these firms.
Tank car lessors beyond the majors
Union Tank Car, GATX, TrinityRail, and Procor own most of the leased tank fleet, but a lined car, a small pressure fleet, or a short term is often easier to find one tier down.
| Company | Based in | Car types | Worth a call for |
|---|---|---|---|
| PNW Railcars | Portland, OR | General service 15,000–30,500 gal, coiled/insulated, lined, 33,000 gal pressure | Lined cars; formerly CAI Rail |
| Modern Rail Capital | Chicago, IL | DOT-117 and 112, stainless, fully lined | Terms from one to five years; formerly Mitsui Rail Capital |
| Southwest Rail Industries | Weimar, TX | General service 10,500–30,000 gal, multi-compartment, pressure 17,000–34,000 gal | LPG and anhydrous ammonia |
| Midwest Railcar | Edwardsville, IL | Pressure (LPG, anhydrous), general service, stainless | Per-diem deals; also buys and leases back |
| Chicago Freight Car Leasing | Schaumburg, IL | General service 13,000–33,000 gal | Acids, fats and oils, corn syrup, fertilizer |
| First Citizens Rail | Chicago, IL | General service 23,500–31,000 gal, pressure | Bank counterparty; formerly CIT Rail |
| RESIDCO | Chicago, IL | General service and acid-service tank | Mid-size lessor and wholesaler |
| GLNX Corporation | The Woodlands, TX | General service tank | Built around medium and smaller shippers |
| TCIX Rail | Tulsa, OK | Tank cars in several sizes, lined and unlined | Short and long terms |
| Everest Railcar Services | Cave Springs, AR | General service and pressure | Short-term leases and sales |
| Infinity Transportation | Atlanta, GA | Tank cars from molasses to chemicals | Mid-size lessor |
Covered hopper, gondola, boxcar, and flatcar lessors
For dry bulk, steel, scrap, aggregate, and boxcar freight, these are the second-tier lessors worth a call after (or instead of) the majors.
| Company | Based in | Car types | Worth a call for |
|---|---|---|---|
| Chicago Freight Car | Oak Brook, IL | Covered hoppers, pressure-differential, flats, mill gondolas, open-top hoppers, tank | Broad mid-size fleet |
| Midwest Railcar | Edwardsville, IL | Covered hoppers, PD, gondolas, boxcars, open-top hoppers, flats, autoracks | Lessor and broker; per-diem deals |
| DJJ Rail Equipment Group | Cincinnati, OH | Steel and scrap, grain, aggregate, and plastics cars | Short and long terms; leasing and sales |
| RESIDCO | Chicago, IL | 3,235 cu ft open-top hoppers, high-side gondolas | Often has cars available now |
| CarMath | Brandon, SD | Open-top hoppers, PD, gondolas, covered hoppers, boxcars | Small to large orders, per diem |
| SB Railcar | — | Boxcars, flats, mill/coil/twin-tub gondolas, covered hoppers, open-top hoppers | Short-term leases |
| I.C.E. Service Group | Moon Township, PA | Gondolas, flats, boxcars, hoppers, coil cars | Small lessor |
| PNW Group | Kent, WA | Gondolas, flats, boxcars, hoppers | Small dealer-lessor |
| ATEL | San Francisco, CA | Diversified freight cars | Investor-backed mid-size lessor |
| Florail | DeLand, FL | Freight cars | Small lessor |
Small quantities and short terms
A major lessor's primary desk rarely wants a four-car, six-month deal. These firms do: they are dealers, brokers, and remarketers that work the secondary market.
| Company | Based in | Car types | Worth a call for |
|---|---|---|---|
| CRMS | Chicago, IL | Tank, covered hoppers, gondolas, boxcars, specialty | Weeks-to-months and seasonal deals; broker with no captive fleet |
| RTEX | Jacksonville Beach, FL | All car types | Lessor, dealer, and broker for anything from 10 to 200 cars |
| Railbroker | Houston, TX | DOT-117J and 117R, general service, coiled/insulated tank | Short-term, from five cars up |
| PFL Petroleum Services | Naples, FL | Pressure and non-pressure tank | Individual units and subleases |
| Sterling Rail | Austin, TX | All types via classifieds | Subleases, often 6–18 months |
| eRail Commerce | The Woodlands, TX | Tank and freight cars | Broker for smaller enterprises |
| Rail Car Deals | Connecticut | Tank and freight cars, sale or lease | Broker and listings |
Heavy-duty, maintenance-of-way, and specialty cars
| Company | Based in | Car types | Worth a call for |
|---|---|---|---|
| Herzog | St. Joseph, MO | Rapid-discharge, side-dump, gondolas, flats, ballast cars | Maintenance-of-way and aggregate work |
| Kasgro Rail | New Castle, PA | Depressed-center and heavy-duty flats up to 16 axles | Oversize and transformer loads |
| TTX equipment sales | Charlotte, NC | Retired flats, bulkhead flats, boxcars | Sells cars for in-plant and bridge use |
Canada and Mexico
| Company | Based in | Car types | Worth a call for |
|---|---|---|---|
| Procor | Oakville, ON | Tank cars and specialty hoppers | Union Tank Car's Canadian arm |
| ANCAF | Mexico City | Chemical, fertilizer, and energy tank cars, plus freight cars | Mexican lessor; short, medium, and long terms |
Marketplaces and the sublease route. Shippers with idle cars under lease are often the cheapest short-term source of all, because they are paying rent either way. Listings turn up on Commtrex, RailCarTrader, and our own railcar sublease board. If you would rather hand the search to someone who works these desks every week, our railcar brokerage desk sources cars and places idle ones, and you can see recent lease activity on the railcar lease activity tracker.
Who Each Lessor Is Actually Good For
GATX
The oldest name in the business and a publicly traded, rail-only company — which matters, because a lessor whose entire earnings story is railcars behaves differently in a soft market than a bank division that can shrink a portfolio. GATX runs a diversified North American fleet of tank and freight cars alongside operations in Europe and India, and it maintains its own network of company-operated repair shops. Full service is the house product. If you have no mechanical function and no interest in building one, this is the profile you are shopping for.
TrinityRail
The only large player that builds, leases, maintains, and supplies parts for the same cars. That vertical integration is the entire pitch: when nothing suitable exists in the used market, you can order cars to your spec and lease them from the company that welds them, with one contract instead of a build order plus a separate lessor plus a separate shop network. Trinity is also flexible on structure — full-service, net, per-diem, and sale-leaseback all come off the same desk. The tradeoff is that a builder-lessor is naturally happiest selling you a new car when a fifteen-year-old one would have done the job.
Union Tank Car (and Procor)
A tank car specialist that builds its own equipment, operates its own shop network, and leases almost exclusively on a full-service basis. Procor is the Canadian arm, so a lease with either gets you continent-wide coverage. If your commodity moves in a tank car — chemicals, refined products, edible oils, asphalt — this is a first call. If you need covered hoppers or gondolas, it is the wrong door, and our guide on where to find tank cars for lease walks through the sourcing sequence in more detail.
AITX
The combination of the former Andersons rail group and the SMBC Rail Services fleet (itself built on American Railcar Leasing). A diversified lessor with a deep covered hopper and tank book and, unlike most majors, a real appetite for per-diem and shorter deals. If a major has to be on your list for a small or seasonal need, this is a good one to include.
First Citizens Rail, GABX, and the finance-led lessors
Bank- and investor-owned lessors, grouped together because they behave alike: First Citizens Rail (the former CIT Rail), the GABX fleet that was Wells Fargo Rail, and Modern Rail Capital (formerly Mitsui Rail Capital). Their fleets are diversified, their strength is capital, and their natural deal is large, long, and structured — including sale-leasebacks, where you sell them a fleet you already own and lease it back to free up the cash. They can be very competitive on rate for a real fleet on a real term. They are generally less interested in your four-car seasonal problem, and their maintenance offering varies by fleet and deal, so read the scope rather than assuming it matches a full-service lease from a shop-owning lessor.
Greenbrier and the second-tier builder-lessors
Builders that lease a portion of their own output and, in Greenbrier's case, also manage large fleets on behalf of other owners. Worth a call when you want new equipment, when you want someone else administering the fleet paperwork, or when a builder is trying to place cars from a cancelled order — that last situation is where genuinely good pricing on new equipment tends to show up.
Mid-size lessors, dealers, and remarketers
Below the majors sits a layer of smaller lessors, dealers, and remarketing firms that buy, sell, and re-lease used equipment, plus commodity-specific players such as agricultural companies with their own car fleets and repair shops or scrap processors leasing gondolas. They are the practical answer for a small fleet, a short term, a seasonal peak, or an unusual car type. Expect more diligence work in exchange: older cars, longer service histories, and less time before the next requalification.
Three Business Models Behind the Same Word
Strip away the brand names and there are three ways a company ends up owning railcars, and the model predicts how it will negotiate with you.
Builder-lessors
They manufacture cars and lease them. Fastest path to a new car built exactly to your spec, and they control shop capacity. Their incentive tilts toward new equipment and toward keeping their own plants loaded.
Finance lessors
Banks and investment platforms that own cars as assets. Deep capital, competitive on large long-term fleets, and the right counterparty for a sale-leaseback. Maintenance and compliance may be your job — verify, do not assume.
Operating lessors and dealers
They live on utilization of a used fleet. Most flexible on term and quantity, most likely to have four cars available next month, and most likely to hand you a car with real service history to diligence.
The shipper next door
Not a leasing company at all, but often the fastest source: another shipper paying for idle cars. Requires their lessor's written consent, and it is where short-term needs actually get filled.
Full-Service vs Net Lease
Every lessor sells one of two products, and comparing a full-service quote to a net quote on monthly rate alone is the most common costly mistake in railcar leasing.
A full-service lease bundles the equipment with maintenance, regulatory compliance, and usually the property taxes. The lessor tracks due dates, pulls cars for required inspections and qualification, handles shop routing, and absorbs normal wear repairs. You pay one number per car per month and largely stop thinking about the mechanical side.
A net lease is closer to a finance product. You get the car; you own everything else — running repairs, inspections, regulatory qualification, ad valorem taxes filed in every state the car operates, registry administration, and the cost of shop time and the days lost to it. The monthly rate is lower, sometimes dramatically. Whether it is actually cheaper depends on whether you have a mechanical function and the appetite to run one.
The honest way to compare them is to add an all-in maintenance and compliance estimate to the net quote before you look at either number. If you do not have a defensible estimate for that, full service is buying you certainty, and certainty is worth paying for. Our railcar lease rate reference is a starting point for what current ranges look like by car type, and the lease vs. buy calculator puts leasing next to ownership on the same footing.
The Terms That Move More Money Than the Rate
Shippers negotiate the monthly rate hard and sign the rest. That is backwards. On a multi-year fleet lease, the clauses below routinely swing more money than the rate difference between two lessors.
- Return condition and cleaning. The single biggest end-of-lease surprise. Who cleans the car, to what standard, who disposes of the residue, and what happens if the lessor's inspector disagrees with yours. On a lined tank car this can be a five-figure item per car.
- Maintenance exclusions. "Full service" never means everything. Damage from your loading practice, lining failure attributed to your product, appendage damage, and interchange damage billed under AAR rules are typically outside the bundle. Read the exclusion list, because that is where the real scope lives.
- Mileage allowance. Railroads pay an allowance to the owner of a private car under defined conditions. Whether any of it flows back to you is negotiable and is frequently left on the table.
- Remaining qualification life. Ask for the due dates on every car offered. Cars delivered with a required inspection coming due soon are cars you will lose to a shop shortly after they arrive, and you will still be paying rent.
- Positioning cost. The freight to move cars from wherever they are idle to your loading point is usually yours. On a fleet, this is a real number and it belongs in the comparison.
- Storage. When your cars are idle — a turnaround, a lost contract, a seasonal trough — where do they go and who pays? Some lessors will store on their own tracks at a rate. Others leave you to find space.
- Renewal notice and holdover. Miss a notice window and you can auto-renew for another term, or drop into a holdover rate well above the contract. Calendar it the day you sign.
- Assignment and sublease consent. If your volume disappears, subleasing is the escape hatch, and nearly every lease requires the lessor's written consent. Negotiate a workable consent standard up front, and see our railcar sublease guide for how that plays out.
- Casualty value. The stated schedule you owe if a car is destroyed. Check that it declines sensibly over the term instead of holding near new-car value on an older car.
How to Run a Lease RFQ Across Several Lessors
Write the spec first
Car type, AAR or DOT class, gross rail load, capacity, lining, fittings, quantity, term, and the window you need cars in service. "We need some covered hoppers" is not a spec, and it gets you a slow, expensive quote. Our rail car types guide covers the vocabulary if you are still narrowing it down.
Decide full-service or net before you call
Ask for both if you genuinely might go either way, but ask every lessor for the same two structures. Mixed structures across a bid list produce a comparison you cannot read.
Quote at least four sources, from different tiers
Two majors, one mid-size lessor or dealer, and the sublease market. Confirm the majors are actually independent owners after the last few years of consolidation.
Ask for the terms, not just the rate
Request return condition, maintenance exclusions, mileage allowance treatment, storage, positioning, and remaining qualification life with the quote. A lessor who will not put those in writing before the lease draft is telling you something.
Normalize everything to all-in dollars per car per month
Rate, plus expected maintenance and compliance on net deals, plus taxes, plus positioning amortized over the term, plus expected storage. That number is the only one worth comparing.
Check the quantity against your cycle time
Fleet size is loading time plus transit plus unloading plus return plus a buffer, divided into your volume. Lease too few and you starve the plant; lease too many and you pay rent on parked steel for years. Run it through the rail fleet calculator before you commit to a car count.
When a Leasing Company Is the Wrong Door
Three situations where signing a primary lease is the expensive answer to the wrong question.
You need cars for months, not years. Major lessors price short term at a premium because they carry the remarketing risk when you walk away. A sublease from a shipper with idle cars, or a per-diem deal from a dealer, usually beats it. The railcar marketplace exists for exactly this.
The railroad will furnish the equipment. Not every commodity requires private cars. For some traffic the carriers still supply equipment through car-supply and shuttle programs, and leasing on top of that is paying twice. Ask your serving carrier what they will furnish before you sign anything — a question our rail strategy course module walks through as part of building the program.
Someone else in your supply chain already has cars. On plenty of lanes the supplier or the receiver already runs a fleet and would rather control the equipment than the freight. One phone call can make the entire sourcing exercise unnecessary, and it costs nothing to ask.
And the largest question sitting underneath all of it: whether you should be leasing or owning. Leasing buys flexibility and a known monthly cost. Owning buys a lower long-run cost and full control of the equipment, along with every maintenance and compliance obligation attached to it. Our breakdown of what a railcar costs new and used runs both cases with the numbers that decide it.
Frequently Asked Questions
Who is the lessor in a railcar lease?
In a railcar lease, the lessor is the company that owns the railcars and leases them out; GATX, TrinityRail, and Union Tank Car are the largest examples.
Who is the lessee in a railcar lease?
The lessee is the shipper or other user who pays a monthly rate to use the cars without owning them.
Who is responsible for maintenance under a full-service lease vs a net lease?
Under a full-service lease the lessor carries maintenance, repairs, ad valorem taxes, and usually regulatory compliance, and recovers those costs through a higher monthly rate. Under a net lease the lessee takes on maintenance and taxes in exchange for a lower rate. How running repairs and wheel sets are split varies by contract, so read the maintenance clause before comparing rates.
Who are the largest railcar leasing companies?
The largest lessors by fleet size are GATX (which now also manages the former Wells Fargo Rail fleet under the GABX mark), TrinityRail, Union Tank Car (with Procor in Canada), Greenbrier, AITX (which absorbed the former SMBC Rail and American Railcar Leasing fleets), and First Citizens Rail (formerly CIT Rail), followed by Modern Rail Capital, a group of mid-size lessors, and a long tail of dealers, brokers, and remarketers. Fleet rankings shift with acquisitions, so confirm current ownership before assuming two names are separate desks.
What is the difference between a full-service lease and a net lease?
A full-service lease bundles maintenance, regulatory compliance, and usually property taxes into the monthly rate, so the lessor handles shop time and inspections. A net lease is closer to a finance product: you get the car and take on maintenance, compliance, taxes, and administration yourself. Net rates look lower per month and are not automatically cheaper once you add the work back in.
How do I know who owns a railcar?
Read the reporting mark stenciled on the side of the car. A mark ending in X means the car is privately owned rather than railroad-owned, and the prefix identifies the owner: GATX for GATX, TILX for TrinityRail, UTLX for Union Tank Car, PROX for Procor. That is often the fastest way to learn which lessor already serves a facility you are shipping to.
How long is a typical railcar lease?
Primary leases from the major lessors are usually multi-year commitments, and the largest fleets and best rates are quoted against longer terms. Shorter deals exist, but they come from the secondary market, dealers, and shipper-to-shipper subleases more often than from a major lessor's primary desk, and they carry a premium per car per month.
Do railroads provide railcars, or do I have to lease them?
It depends entirely on the car type. Tank cars are essentially all privately owned, so leasing is the only path. For some commodities the railroads still supply equipment through car-supply and shuttle programs, and in those cases leasing may be unnecessary. Ask your serving carrier what they will furnish before you sign a multi-year lease.
Can you negotiate with a railcar leasing company?
Yes, and the negotiable items go well beyond the headline rate. Return condition, cleaning responsibility, mileage allowance, maintenance exclusions, storage, positioning cost, and renewal notice windows all move real money and are all negotiable. Quote the identical package to several lessors and compare the terms, not just the monthly number.
