LU_fan Posted May 22, 2018 Share Posted May 22, 2018 Not sure this is where it belongs, but here goes. I actually found this thanks to a surprising eBay find. Anyway, in this threads opening post, the third picture seems to show a Class 50 hauling a 4-TC, or possibly a Class 421 or 423. Was this something that happened regularly, or is this a special working? Being a fan of the Hoovers and slightly odd train consists, I thought it might be fun to recreate in model form.

Bomag Posted May 22, 2018 Share Posted May 22, 2018 On various visits to Clapham Junction and Salisbury in 1988/89ish I saw a few 50+4TC - AFAIR they were only used on the Salisbury services. Anything going further west were normally MK2 stock. 1 Link to post Share on other sites More sharing options...
LU_fan Posted May 22, 2018 Author Share Posted May 22, 2018 Ok, so they were actually regular services? Cool. But am I correct in assuming that the 50 could not be controlled from the 4-TC? Link to post Share on other sites More sharing options...
Bomag Posted May 22, 2018 Share Posted May 22, 2018 But am I correct in assuming that the 50 could not be controlled from the 4-TC? The 4TC was used as normal hauled stock - they had normal ETH and drawgear (in addition to buckeye couplings and rubbing plates for being propelled by 4Reps or 33/1s) Link to post Share on other sites More sharing options...
LU_fan Posted May 22, 2018 Author Share Posted May 22, 2018 Being a bit tired, I was just about to say that that didn't quite answer my question, only to realize that it actually did. "4TC was used as normal hauled stock" answers it perfectly. But was that only during NSE days, or did it happen prior to that too? Link to post Share on other sites More sharing options...
RMweb Gold The Pilotman Posted May 23, 2018 RMweb Gold Share Posted May 23, 2018 Stick “Class 50 4TC” into Flickr and that'll bring up a few pictures including one at Exeter St. David’s. 1 Link to post Share on other sites More sharing options...

It was a regular pairing during mid 1989 as 50s took over the Salisbury turns from 33/1s but there weren't enough Mk.2s available initially to replace the TCs. 1 Link to post Share on other sites More sharing options...

manna Posted May 23, 2018 Share Posted May 23, 2018 G'Day Folks As a Guard at Eastleigh, in the mid to late 80's (86-88) there was a regular turn, where we worked a class 50 and a 4TC from Salisbury to Basingstoke weeknights all stations, arriving about 11-1130pm, the 50 was at the front and we awaited time at every station. manna 2 Link to post Share on other sites More sharing options...
LU_fan Posted May 24, 2018 Author Share Posted May 24, 2018 Kind of a follow-up question, but perhaps better suited in its own topic. When used as regular hauled stock, did the 4-TC's ever run with any other kind of stock? Like Mk.1 or Mk.2 coaches? Link to post Share on other sites More sharing options...

LU_fan Posted October 28, 2018 Author Share Posted October 28, 2018 Sorry to dig up an old topic, but this past Friday I was told that at least some of the 50's were rebuilt so they could actually operate a push-pull service with the 4-TC sets. Would anyone happen to have any more information about that? First of all, could anyone confirm if that really did happen? And if so, which locomotives were rebuilt?

Like Mk.1 or Mk.2 coaches? If this did happen, and I have no idea if it did or not, the additional stock would need to be air-braked, as the 50s were the first class not fitted with vacuum brakes or even a through pipe; they could only work with air-braked stock. There were certainly air-braked BGs and GUVs, though. Link to post Share on other sites More sharing options...
RMweb Premium keefer Posted October 28, 2018 RMweb Premium Share Posted October 28, 2018 Class 50s had dual brakes, IIRC the first locos to be air only were the 87s. 1 Link to post Share on other sites More sharing options...

Nearholmer Posted October 28, 2018 Share Posted October 28, 2018 There were a few (six, maybe) buffet (restaurant?) cars that were wired for working between pairs of TCs, but they were considered part of the EMU fleet, rather than "ordinary hauled stock". If you google for pictures of an excursion called the "Thames-Tamar Express" (c1976/77), that was composed of a two TCs, with a wired buffet, and a Class 33 each end ...... I know, 'cos I travelled on it. There was a similar excursion a year or two earlier, billed as the "Atlantic Coast Express", which went to more interesting places, but blowed if I can recall if that was the same formation.

RMweb Gold russ p Posted October 28, 2018 RMweb Gold Share Posted October 28, 2018 Were those fitted with EP brakes Kevin? Not sure how s conventional distributor fitted vehicle would behave in a train of EP stock being worked in EP mode rather than dragged in triple valve mode Link to post Share on other sites More sharing options...
Nearholmer Posted October 28, 2018 Share Posted October 28, 2018 (edited) Very good question, to which I should know the answer, but don't. My guess would be that they were EP fitted. You've made me think of a similar question, related to MLVs and TLVs, the latter of which were also what might be called "loose EMU stock", and I'd guess also EP fitted. The MLVs certainly had a 'proportional valve', which yielded a proportionate brake application between the MLV itself and whatever stock it was pulling, and I think they might have been able to haul both air and vacuum-braked stock, and act as a 'translator' in either direction. The worrying thing about the valves on the MLV is that I can remember where they were, but not exactly what they did ...... bit of a while ago! And, I can't check any of this, because I threw away all my "brakes course" material about two house moves ago. Hopefully there is an RMWebber with a better memory than mine! Edit: This website seems to have the answers to some of the questions http://www.bloodandcustard.com/bournemouth1966.html#PushPull and reminded me that the MLVs had vacuum exhausters.

Bulleidnutter Posted October 28, 2018 Share Posted October 28, 2018 Also, you would have had to change the ETH/ compressor fusing to accommodate a Cl 50 working a TC set as they were fused for 750v, for use with 33s and EDs rather than the 1000v Cl 50s.
