Transfer of lading means moving a shipment from one railcar into another while it is still in the railroad's hands. It happens when a car can't safely finish the trip: the load shifted, the car is overloaded, the blocking broke, or the car itself failed. The car gets set out, the lading gets transferred or adjusted, and someone gets a bill. Who gets that bill depends on why the transfer was needed.
This guide covers what triggers a transfer, how each Class I railroad handles it, what it costs under the current tariffs, and how to tell a fair charge from one you should push back on.
What Transfer of Lading Means
Transfer of lading is the work of unloading a shipment from the car it was billed in and reloading it into a different car, mid-route, so the freight can keep moving. "Lading" is just the freight in the car. The railroad tariffs usually lump transfer in with two related jobs: adjusting the load (re-blocking, re-bracing or reducing weight in the same car) and repackaging it.
BNSF's rules book calls the item "Transferring, Adjusting or Repackaging of Lading." Norfolk Southern describes the same work as re-blocking, re-bracing or transloading to another railcar. CSX talks about "a weight reduction, load transfer or load adjustment." The names differ, but they all cover the same thing: freight that can't stay in the car it's in.
It's different from a planned transload, where you move freight between truck and rail at a terminal on purpose. A transfer of lading is unplanned. It's an exception, and it's billed like one.
Why Railcar Loads Get Transferred
Most transfers come down to one of two problems: the load or the car. Here are the common triggers:
- Shifted or broken securement. Coils roll, lumber bundles slide, crated machinery walks off its blocking. Once a load moves enough to break the car's clearance or balance, it can't go on as is.
- Overloads. A car over its load limit, or over the weight limit of track on its route, gets stopped. Sometimes the fix is taking weight off into a second car. See our guide to overloaded railcar charges for the weight side of this.
- Unbalanced loads. Freight loaded heavy to one side or one end. CSX's tariff treats an unbalanced car as unsafely loaded.
- Leaks. A hopper gate that won't stay shut or a tank car valve that weeps. Fixing the car may mean emptying it first.
- Mechanical failure of the car. A bad-ordered railcar with a cracked sill, failed truck or damaged door may not be repairable with the load still inside. The freight goes into a replacement car.
- Wreck or derailment damage. If the car is damaged in an accident, whatever freight can be saved gets transferred.
The first four are loading problems. The last two are equipment or carrier problems. That split decides who pays, so keep it in mind.
What Happens When a Car Is Set Out
When a crew or car inspector finds a car that can't move safely, the car is set out of the train and held. The railroad then notifies the shipper. From there, the tariffs follow a similar order:
- The car is set out and placed in a held status. UP calls it "improperly loaded status." The car sits until there's a plan.
- The railroad notifies the shipper. If your contact details at the railroad are stale, this notice goes nowhere and the clock runs anyway.
- The car is moved to a work track. The railroad picks the spot. You pay the switching to get it there and back.
- The shipper arranges the work. NS states plainly that it won't furnish any personnel, equipment or machinery. You hire the contractor, and on BNSF that contractor has to meet BNSF safety rules and you sign a release of liability before work starts.
- The deadline runs. UP gives you 48 hours from notice of the car's location to adjust the load. CSX wants a written correction plan within 48 hours. BNSF uses "a reasonable time" decided case by case.
- If you don't act, the railroad does it for you and bills the cost plus a markup.
- The car moves again once the railroad has the fix confirmed and has power and crews available.
Demurrage or storage usually runs the whole time. NS and CSX say so in the same item, and BNSF points to its demurrage tariff. A car that sits a week waiting on a contractor costs real money before anyone touches the freight.
What Each Railroad Charges
Each railroad charges a fixed penalty when it finds an improperly loaded car, then bills the actual work on top. Here is how the current tariffs compare:
| Railroad (tariff) | Flat charge | If the railroad does the work | While the car waits |
|---|---|---|---|
| BNSF (6100-C Item 3030) | None if you do the work yourself in time | $5,225 plus actual cost plus 20% | Switching per BNSF 8005, demurrage or storage per BNSF 6004 |
| UP (6004-C Item 8001-A) | $4,000 per improperly loaded car | Shipper pays all costs of moving and adjusting | 48 hours to adjust after notice |
| NS (8002-A Item 5040) | $4,000 per car; all penalties doubled after the shipper's 3rd improperly loaded car in a calendar year | Shipper pays all costs of re-blocking, re-bracing or transloading | $250 per day from notice that the car is ready for adjustment |
| CSX (8100 Section 1.3.3) | $5,000 first offense, $10,000 second, $15,000 each after | Contractor cost plus a 15% handling fee | Demurrage until corrective action is done |
| CPKC (Tariff 2 Item 52) | Major adjustment: cost plus 25%, $1,000 minimum per car ($2,000 for hazmat or residue) | Transfer trailer, if mobilized: $5,000 per day | Other applicable charges also apply |
Three details in these items matter more than the headline numbers.
The extra car is not free
If part of the load has to go into a second car, CSX bills that car at the same rate as the original, as if it were moving over the originally billed route under the same price. You pay two line hauls for one shipment. Ask early whether the freight can be adjusted in the original car before agreeing to a split.
Signing the bill of lading doesn't shift the risk
UP's item says that signing Section 7 of the Uniform Straight Bill of Lading does not relieve the shipper from the improper load charge. Railroad acceptance of the car doesn't waive anything either. If you loaded it, the loading is yours. Our post on shipper load and count vs carrier load explains why.
Damage during the transfer can land on you
NS's tariff says any damage to the load caused by the re-blocking, re-bracing or transloading is the shipper's responsibility unless it was caused by NS's gross negligence. If a coil gets dented coming out of the gondola, that's your loss, not a claim against the railroad.
Who Pays: Shipper, Car Owner or Railroad
The shipper pays when the transfer is caused by how the car was loaded. The private car owner's side pays when its equipment failed. The railroad pays when it caused the problem. The tariffs say this pretty directly:
- Loading and securement: BNSF puts every transfer, adjustment and repackaging cost on the shipper, including cleaning up spilled or astray freight, "except on proof by the shipper of BNSF negligence." It ties the shipper's duty to Rule 27 of the Uniform Freight Classification.
- Private equipment failure: BNSF's same item extends that responsibility to transfers "made necessary by the failure of privately-owned rail equipment" and other owner-responsibility situations listed in AAR Interchange Rule 96. If you lease the car, read the lease to see whether the lessor covers this.
- Railroad fault: NS states that it pays for the re-blocking, re-bracing or transloading when the shipper fully complied with the loading requirements and the problem was caused solely by NS.
Note who carries the proof. Under the BNSF wording, the shipper has to prove railroad negligence. Under NS, you have to show you fully complied with the loading rules. That means photos at loading, a written securement plan and the AAR figure or approved drawing you followed. Without them you have nothing to argue with.
When a transfer happens after a wreck or a rough-handling event, ask about weights. UP's tariff (6004-C Item 5030) says that when lading has been transferred en route, after an accident, or for other reasons where there is evidence of loss in transit, the carrier will weigh or reweigh the car when possible. NS has a similar rule. Compare that reweigh against your origin weight. If freight was lost or damaged in carrier hands, that's a rail freight claim, which has its own deadlines.
Illustrative Example: A Gondola of Steel Coils
This example is illustrative. The tariff charges are real; the scenario and timeline are made up.
A service center ships a gondola of hot-rolled coils on NS. Partway through the trip, an inspector finds two coils have rolled off their chocks and broken the blocking. NS sets the car out and notifies the shipper on a Monday.
- The shipper gets hit with the $4,000 handling charge under NS 8002-A Item 5040 as soon as the car is flagged.
- The shipper needs a crane contractor who can work at the set-out location. Finding one and getting it scheduled takes until Friday. At $250 per day from notice, four days add $1,000.
- The contractor finds one coil has a damaged edge and the car's floor is gouged. The coils go into a different gondola. The contractor's invoice, the replacement car arrangement and the damaged coil are all the shipper's cost.
- This is the shipper's second improperly loaded car this year. One more, and every NS penalty on later cars doubles.
Before the contractor's bill, the shipper has already paid $5,000 on a car that may have cost less than that to move. The fix was a few dollars of better chocks and a securement plan built on the AAR figure for coils in gondolas.
How to Avoid a Transfer
Transfers are mostly preventable, because most of them start at the loading dock. A few habits cover most of the risk:
- Load to the AAR rules for your commodity and car type. All five tariffs above point to them. Our guide to AAR loading rules for breakbulk covers the common figures.
- Weigh before release. Check the stenciled load limit against your scale, not an estimate.
- Photograph every car before release. Blocking, bracing, doors, gates and seals, with the car number in frame.
- Inspect the empty car you're given. Reject cars with damaged floors, doors or gates before you load them, and write it up.
- Keep railroad contact lists current so a set-out notice reaches someone who can act the same day.
- Line up a transfer contractor in advance on your main lanes. Under a 48-hour deadline, you don't want to start making calls after the notice arrives.
If a car is already stuck, our managed rail service handles the exception for you: talking to the railroad, sourcing the contractor and checking the bill line by line. It's the same work described in our guide to railcar exception management.

Frequently Asked Questions
What is transfer of lading in rail shipping?
Transfer of lading is moving a shipment from the railcar it was billed in to another railcar while it's still in the railroad's possession. It happens when the original car can't safely continue, usually because the load shifted, the car is overloaded, or the car broke down.
Who pays for transferring a railcar load?
The shipper pays when the transfer is caused by how the car was loaded or secured. BNSF's tariff also puts costs on the shipper when a privately owned car fails. The railroad pays when it caused the problem, but the tariffs make the shipper prove it.
How much does a railroad charge for an improperly loaded car?
UP and NS charge $4,000 per car, with NS doubling penalties after a shipper's third improperly loaded car in a calendar year. CSX charges $5,000, $10,000 and then $15,000 per offense. BNSF charges $5,225 plus cost plus 20% if it has to do the work itself.
How long do I have to fix an improperly loaded railcar?
UP gives the shipper 48 hours after notice of the car's location to adjust the load. CSX wants a written correction plan within 48 hours or it may fix the car itself. BNSF allows a reasonable time decided case by case. Demurrage or storage usually runs while you wait.
Do I pay freight on the second car if my load is split?
Usually yes. CSX's tariff bills the extra car at the same rate as the original, as if it moved on the originally billed route under the same price. Ask whether the load can be adjusted in the original car before agreeing to split it.
