Blue Star fitted Mark 2s

[WatsonPD]

I know DRS has some mk2 and DBSOs fitted with blue star MW system for push-pull operation. Arriva Northern used some mk2s and two EWS Cl37s in Top and Tail formation, using blue star through coaching stock. BR Scotrail was using Cl27s and mk2s using blue star for push-pull before DBSO was a thing and I recently learned that Wessex Trains once used some mk2s with two Fragonset Cl31s in T&T - again using blue star.
So I'm wondering which mk2s coaches are fitted with blue star (number range) and are there any other push-pull operations using this method? Thanks

All the Mk2s used for Network Rail infrastructure monitoring trains have Blue Star through-wiring for use with top-and-tail class 37s, and the Network Rail DBSOs all use that standard for push-pull working with 37s. Off the top of my head (this is not a complete list by any means):

PLPR recording vehicles 72631, 5981, 1256, 72639
Track Recording Coach 999550
Track Inspection Coach 2 977974
Electrification Monitoring Vehicle 977983
Radio Survey Coaches 977868, 977983
DBSOs 9701, 9702, 9703, 9708, 9714
Structure Gauging trains 1 and 2 (each one recording vehicle plus permanently-coupled brake runner, don't know the numbers off the top of my head)
Assorted brake force runners, too many to list

I wasn’t aware that DRS had any Mk2/DBSO rakes left - the DBSOs have most/all been sold on.

I saw 37175 in Westbury (19/07/2023) with the following test train:
9714
62287
9808
6122
96604
I imagine these would be blue star fitted?
