  1. Yes the TDM equipment was removed, the cupboard is still in brakevan. Bluestar was added on so we have a jumper cable and throttle pipes, also note the MK2s have had to have these additional fitments added as well.

    Excludes the possibility of 37/4 push-pull working in the 1980s; but not, necessarily, of them pulling sets of push-pull stock. That’s not something I ever saw, but I remain curious as to whether anyone else ever saw that?

  2. DBSO is worked via a Blue Star arrangement and they have been retro fitted with a control pipe and blue star equipment. A 37 controller has been installed instead of the old unit type controller. If I remember right the NR versions use a 31 controller.

    Previous use on Intercity services was via the Time Division Multiplex (TDM) using the RCH cables.

    Thanks, so the modification required for the DRS workings was to the DBSO, rather than the 37/4?
  3. I was hoping that I might be able to ask a few questions about the capabilities of Class 37/4 locomotives to work with Mk2f DBSOs. I am aware that DRS has been operating these on Cumbrian coast services in recent years, but I am wondering when and how these locomotives acquired a push-pull capability?

     

    The main questions that I have are:

     

    1. What push-pull equipment is fitted to the 37/4s (i.e. were these locomotives retrofitted with suitable equipment to ensure compatibility with the DBSOs; did they already have the capability through blue star multiple working equipment; or is there another technical explanation)?

    2. If they had to be retrofitted with push-pull equipment, when was this done?

    3. If the push-pull capability existed from the outset using multiple working equipment, is anyone aware of any occasions when 37/4s substituted for 47/7s on the ScotRail Express services between Edinburgh, Glasgow and Aberdeen in the 1980s, making use of push-pull working?

    4. If they did not have push-pull capability when initially rebuilt as 37/4s, is anyone aware of them working sets of ScotRail Express push-pull rolling stock on a pull-only basis (as occasionally happened with Class 47s in the event of unavailability of a 47/7 or a fault in the push-pull equipment)?

     

    Any information is very much appreciated!
