For the most part departmental renumbering is a thing of the past. Worth mentioning that the Track Recording Unit (950001) is not and never was a class 150.
If they are referring to the 'Yellow 37s" as they are fitted with ETCS for Cambrian working, the different cab layout and operation with the ETCS in Level 0 probably pushes them outside normal 37 competency.
Indeed, before the early 2000s, it was of course a Class 180. Bit of a change in numbering to go from that to 950.
Indeed, AIUI things like TPWS and AWS are handled through the ETCS interface so specific training is required.
If they don't sign them then they don't sign them.
The example I had in mind was when some 97s were just bog standard 31s and 40s and whatnot, just with dedicated uses. Oh, I do 31s but not 97s. Maybe that's why the research department 31 got renumbered back into the 31 series, I don't know.
Aye, and even when compared to ETCS-equipped Class 37s (Hitachi or Siemens), they'll certainly be very different.
Then it is the management responsibility to keep the paperwork up to date!
It sounds like an excellent idea as it also removes the need for loco-hauled RHTTs to be top & tailed, and it may be a lot easier to path transits where significant MU differential speeds are present.
