What did for the 45s?

[hexagon789]

Off topic but if a pair of 37/4s are used does the ETH index available remain at 38 (that of one loco) or 76 (that is the two combined can provide ETH together)?

Only one loco can provide ETH in a pair.

Pairs of 31/4 provided sufficient ETH index, whereas a single 37/4 didn't; and in the mid 1980s, the 37/4s were allocated to Eastfield and Inverness depots and to Cardiff Canton depot for services in those areas. I can't recall if any 37/4 allocated to Bristol Bath Road.

No 37/4s were based at Bath Road. The allocations, pre-Sprinterisation, were:
37401-413 Eastfield
37414-421 Inverness
37422-425 Eastfield
37426-431 Canton

Thanks @43096 that ties exactly with my memory.

You mean from Stranraer? Dont think they were cleared for that route anyway. The data in the photo implies it is on a Carlisle service. The photo and time add up. There was a 1240 in 1981 service to Carlisle, stopped at Dunlop and Stewarton as well as the other GSWR suspects.

A 40 made it there!

A 40 made it there! View attachment 184697

What is their RA? I think then the route was RA8 it is now maybe RA5?

 

[D1511]

40s were RA6

Well, yes.
Not my photo.

I am fairly sure that I have read of 40s being used on the longer trains to and from Stranraer.

Was it not the case when 40s were replaced on the sleeper by 47s the latter required a pilot engine during bad adhesion due to not having sanders fitted - the 40s had a much lower axle load than 47s hence a wider route availability.

Extract from Scottish Region Sectional Appendix:

CLASS 37/4 LOCOMOTIVES
General
ETH wiring on Class 37/4 locomotives is rated at 150 amps as opposed to 600 amps on other locomotives and shore
supplies.
The train supply jumpers must never be coupled at both ends of a Class 37/4 locomotive unless when two locomotives
are working a train and the other locomotive is also a Class 37/4.
A Class 37/4 locomotive must never be coupled to a shore supply.
Hauling of 'Dead' Locomotives
A Class 37/4 can be utilised to work a train with a dead ETH locomotive of another class on the train providing the ETH
index of the train does not exceed 30 or the ETH is switched off.
A Class 37/4 must not be hauled dead on a train worked by any other class of ETH locomotive which is providing ETH
power to the train.
Failure to comply with these instructions may heat the ETH cabling which could cause permanent damage to the
locomotive equipment.

The bogies were always a problem with 'Peaks' - prone to cracks. I remember the Power Controllers at Euston House ran the Midland Lines ones in two fleets, and the ones with cracks were restricted to freight while they built up the miles to a General, with the very worst on 'ballast'. An area of Derby Works used for storing condemned locos also always contained a number of tired Peak bogies, presumably there was a float. On a visit to Horwich Works, long after all the 1-Co-Co-1s had been built, there were what seemed to be newly-built 1-Co bogies, though I'm not sure if they were for "Peaks' or EE4s. They may well have been new sideframes re-using all the other components, but they were immaculate.

Interesting, I'd always been informed/read that loco sharing of ETH wasn't possible; hence the few air-con workings 37/4s did operate being restricted in length.
