Roger Smith OO LINE19 GWR & BR 3-Character Train Descriptions

3-character train description numbers as used by the GWR and BR Western region during the steam era. These numbers were carried on the smokebox front of steam locomotives and front of the early Warship diesels, allowing signalmen to identify the approaching train and have the correct route set for it, especially important on busy west-of-england summer saturdays when trains could easily get out of sequence.
