Instructions written to be rubbed out.
Also known as: Wagon chalk marking, Shunting chalk mark
The chalk marks written on a wagon or a carriage recording its destination, condition or required work.
Record a rail vehicle's destination, condition or the work it requires.
Contexts: Public information
Written to be erased, so the marking always describes the vehicle's present task and never its history — the medium was chosen because the information had a short life.
Contexts: Public information
Sits alongside painted markings that are permanent, so a wagon carries a fixed identity and a changing instruction in two different media on the same panel.
Contexts: Public information
Letters, numbers and simple figures chalked on the side or the solebar of a vehicle, wiped off and rewritten as the vehicle's task changes.
