class 20 & 31

[TDK]

For anyone iterested I saw 6 class 20's today at Ruilsip LUL depot and a class 31 on the back of the NR train with a yellow 37 on the front at Shrewsbury, the 31 was in BR blue. The 20's, 4 were blue and 2 of them green

The blue 31 would be 31106, the blue class 20s would be DRS 20/3s used on the Underground S-stock movements.

And the yellow 37 will be one of the 97/3s probably on ERTMS testing, though sounds like NR are a bit short of their 97/3s for some reason or another, as they usually run in pairs, t-n-t, but for some reason in this instance a 31 is standing in.

It was 97301 which isn't fitted with ERTMS.
