Rail carload and transload software
Every car on your siding, and how long before it costs you.
Cars get ordered, placed, loaded and released, and demurrage starts the day free time runs out, whether anyone is watching or not. Roadmark draws your siding the way the railroad sees it and colours every car by the free time it has left.

Questions
Questions about cars and demurrage.
Does Roadmark track a railcar's free time and demurrage?
Yes. Roadmark draws the siding the way the railroad sees it and colours every car by the free time it has left, so it's clear which cars are already running demurrage and which are close to their last free day.
How does Roadmark plan a transload?
When a car is ready to unload, it splits the load across trucks that each stay under a legal payload and spaces them so the customer's dock takes one at a time, starting with whichever car is closest to its last free day.
How do you track where a railcar actually is?
Roadmark turns the railroad's own shorthand status messages into a plain trip: where the car is, who has it, and whether it's actually spotted or only constructively placed.
How is transload billing calculated?
It's billed per truck or per ton, with storage and the railroad's own demurrage carried through at cost, the same way the siding actually charged for the car.
Thirteen modes, one platform.
Every mode runs on the same customers, loads and invoices, so a company that runs more than one sees them together.
