As well as lamps, the Castle Class also has headboards which can be changed either during gameplay or in the Scenario Editor. Using the key combinations CTRL+6 and CTRL+5, the player can cycle through the headboards. Each headboard has a corresponding Train Reporting Number, one for the Up Direction (travelling towards London) and one for the Down Direction (travelling away from London).

For those creating their own scenarios, it is also possible to set the headboard by changing the 8th character of the locomotive number with the appropriate letter within the scenario editor.

For example, if the locomotive is to be numbered 4082 and it is a class A train with the Torbay Express headboard for a Up Train, then the value to set in the loco number is 4082a##2A. If the locomotive is to be numbered 5089 and it is a class A train with the Capitals United Express headboard for a Down Train, then the value to set in the loco number is 5089p*#DA.
