1) 108: class 40 turbo
2) 133: bendy bogies- I have a note from the cl37lg committee that 37175 bore these, but also I see that 37133 was in doncaster works in 1984 alongside some 50s undergoing HGR and I wonder if this was when it had these. Gordon Sellers said it was 133 which had bendy fitted (articulated bogies, persumably like US locomotives have)
3) far north mixed freight-passenger
4) class 20 pilot WHL
5) end to end, Greenock to Aviemore: other end to end workings pre 1990?
6) 37/0s which became /1s upon repair
7) 37 296 reallocation before "fouring"
8) the proposed small diesel ETH generator in the wiki pdf on the D6700s
9) the pairs used to propell the APT on the non wired ECML
10) working the Flying Scotsman ( 1S45) in 1960 blip
11) tripples to Llanwern
12) doubles for swaps and run ins: more common than I rememeber on the WHL, the of course the georgemas junction loco and the 37/4 run ins.
13) unusual workings pre 37/4x/5 etc upgrades: glasgow QS low level, the sleeper through to Central etc. 1S81 and the whole thing
14) the 37/3s at ML * see below # 24
15) doubles in the West Country on high seped trains in the 60s/ 70s : failure? Better than d1000s?
16) lickey bankers, QS tunnel bankers...:other bankers??
17) THe early scottish allocation to Grangemouth
18) the glasgow edinburgh push pull trial of 37s
19) the use of 37s to replace 47/7s in july 1984- what happened?
20 ) routes which hardly ever saw thirty sevens in the 70s and early 80s
21) the converse;: routes the 37/4s etc came to run on frequently post 1986 which had never seen 37s before.
22) 37292s uprating to 2000hp
23) why the locos were chosen to become 37/4s and /9s.
24) Oddity: scotland chooses the reverse of welsh steel trains: ML depot trialled both class 56s and later 58s on the hunterston iron ore trains and coal fuel trains for Ravenscraig, and decided resolutely that a pair of thirty sevens out performed single 56s or 58s. Pt Talbot - LLanwern trains used pairs of 56s, and were of course faster than even the triple 37s. But maybe due to the diagrams, there was no advantage seen in going over to single type 5s. This could have been a little biased by MLs management having gathered good operating 37s over time and wanting to retain both head count in fitters and not burden them with a whole new set of training, failures and spare parts.
