Two shots of 37 411, taken a couple of years apart. Opposite sides of the loco, but both of no. 2 end. Spot the difference.
37680, yet another horn move plus a repair patch.
Two shots of 37697, different variations on the black headcode at each end - different locations but taken around the same time.
I'd almost forgotten about this one, 37704 pretending that it hasn't been rebuilt.
Lastly 37707 with the full number between the markers.
ps The shot of 37138 a few posts earlier is at Newport.
