UK Steam Adventures - Part 3 

Trains on the West Somerset and Swannage Railways. Of note are the
differences between GWR and SR engine designs. The sharp exhaust beat
of the GWR loco's versus the soft beat of the Bulleid. And you do have
to pity the GWR crew with that cab design, even though a year later
than the SR loco it still looks like something out of the 19th century.
