The digits give the category of the train, for example 1-150 for year-round fast trains and 701-750 for high-speed trains. Trains to the north and east have even numbers, trains to the south and west have odd ones, and a train takes the paired number on the way back. The letter makes the number unique and relates to the railway of departure or arrival.",
