Plenty of photos & videos exist. In the '60s/70s Fort William trains from Glasgow (inc. sleepers) were often 27 + 20, the 20s used had a through steam pipe to avoid having to turn the locos. Edin-Inv trains were double headed with 24/26s (or 24+26) and sometimes had an extra 24 added. Other trains in the WTT were diagrammed for 25/27 (or 25+27). I think these were done like this, as each combination was matched i.e 24 & 26 were 1160hp and 75mph, 25 & 27 were 1250hp and 90mph. Though, if needed, no doubt any available working combination would be used. Link to post Share on other sites More sharing options...

RMweb Premium Davexoc Posted November 29, 2020 RMweb Premium Share Posted November 29, 2020 Delving through 1983 Modern Railways Pictorials this afternoon found some oddities. 25+40 came up several times, BOC tanks and track recovery from Woodhead, plus a 2x25+40 25+45 on a St Pancras - Derby passenger working 3x33 with 2 in multi and the other in tandem 2x31 assisting a 58 which had failed, but the 31s were inside, with the 58 leading 2x20 but in nose to cab formation 1 Link to post Share on other sites More sharing options...

The Ravenscraig ore trains were usually 3 x 37, but the third loco was sometimes a 26, being added for the climb to Holytown. Was told the reason for a max of three was due to a combination of volt drop through the jumpers and air pressure loss the reg air side, however when we asked the instructor who told this what about the Edinburgh Glasgow push pulls, he looked a bit bemused. 2 Link to post Share on other sites More sharing options...
Zomboid Posted November 30, 2020 Share Posted November 30, 2020 I believe the MU gear on 45s at least was removed pretty early. An MU arrangement on a peak (or a 40) would mean that the front loco and half rear locos tractive effort is transmitted by the rear bogie bearing on the second loco, which i think caused problems. That and the need to multi type 4s was pretty limited anyway. 1 Link to post Share on other sites More sharing options...

DRS 37s have worked along with NwR 37s on test trains for example. I think its only a different connector - IIRC that it is a more reliable as well! (no doubt Russ will confirm/deny). Not quite locos, but the Network Rail RTOVs and the DRS DBSOs are Blue Star, as is 975025 Caroline.

It was thought that there was nothing could move it if it died, especially on a bank. I am not sure that was the case, as I understand it they did not need three locos for tractive effort, but speed where horsepower is king. The ore trains ran on the main line between HSTs, and they needed to accelerate the train quickly to its 60mph maximum speed, and keep it there or thereabouts in order to complete the run without delaying the following HST. I believe that a pair of 37's could haul the train over the route without difficulty, just not fast enough! 1 Link to post Share on other sites More sharing options...

Firecrest Posted December 3, 2020 Share Posted December 3, 2020 The nose end of 131 is quite intriguing - seems to have had a pair of nose end doors from a disc fitted loco added at some point - note the holes for the marker lights... 127 was the same but kept the discs Link to post Share on other sites More sharing options...

It was also quite common to have Class 20s as pilots between Stranraer and Ayr with 47s so in tandem rather than multiple. Pretty sure I've seen them used with 40s and 27s on that line too, but photos are eluding me at the moment 2 Link to post Share on other sites More sharing options...
