TOPS Code/Class: AB21 Previous Next
TOPS Category: ?This is my own (unofficial) means to categorise TOPS codes based on what they relate to and whether they are long (4 characters, i.e. including sub-codes) or short (3 characters) LC - Long Code, Coaching Stock In selection ?This works on your last-used TOPS selection, including any filters and sort orders. 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). A - Passenger-carrying coaches 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
