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.

## One car of resin, four bays, four trucks.

When a car is ready to unload, the Planning agent splits it across trucks that each stay under a legal payload, and spaces them so the customer's dock takes one at a time. The car closest to its last free day goes first.

## From release to the siding, in words your team already uses.

A car's own events arrive as railroad shorthand. Roadmark turns them into a plain trip: where the car is, who has it, and whether it's actually spotted or just been promised a spot.

## Transload fees, storage and demurrage pass-through, on one invoice.

Billed per truck or per ton, with any storage and the railroad's own demurrage carried through at cost, the same way the siding actually charged for the car.

## 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.
