Drawings of GWR Locomotives
4 Coupled Tanks
The variations in the 19th Century classes create a positive
minefield for modellers: a locomotive could go into the works for a
heavy overhaul and come out looking as if it were of a different
class. The 517s and Metros listed here are particularly notorious for
endless variety. Whilst bunker and cab shapes are the most common
variations even things like the axle box design varied over the
years. Working from a photograph of an individual locomotive is
highly recommended.
The drawings are in roughly
chronological order.
If you can look at these drawings and gain a
greater understanding of how these locomotives evolved over the years
then I will have achieved my aims with these sketches, but if you use
them for anything beyond the simplest "plastic bashing"
representational modelling then I have done you a disfavour by
creating them.
The drawings are arranged so they can be opened in
individual tabs of a tabbed browser and flicked between to look at
the changes. Whilst they are to a consistent scale, I deliberately
haven't shown the scale because of the various caveats noted above.
