What is the DB/NR working?

[Crossforth]

Anybody know which the two 67s were that were top and railing the (what I assume to be an NR mark 1?

One 67 was in W&S colours and the other in DB red.

I saw it in Marsh Lane cutting outside Leeds

A mark 1 that will run at 125mph?? Can't be many of them about!!

1Q17, I believe this is running vice the NMT which normally does Derby RTC - Heaton T&RSMD SO. The 125mph shown is the timing load and does not neccessarily reflect the actual consist working for a given day. However, the test stock that normally substitutes for the NMT tends to be Mk2s.
