Buttons will not show if the current TOPS code was not in your last selection, or if you are at the beginning or end of the data set.
TOPS GENKOC: ?The first character of a TOPS code is known as the GENKOC and indicates the general type of rolling stock (e.g. 1xx are DMUs). 0 - Locos Overall ?This works on the overall TOPS code list without any filtering or sorting applied.
TOPS BRAKTY: ?The third character of many TOPS codes is the BRAKTY, indicating the type of braking equipment fitted (e.g. A indicates air brakes). * - Not defined by code
