40069
55019
50018
86101
There's probably scope here for another thread (or a sub-thread of this one) regarding personally most hated locos, but I won't stray there just yet ...
Just to expand a bit on my earlier post:
40069 was a York loco when I lived in York and first became interested in bashing. For some reason it seemed slightly stronger than some other class members - perhaps it was more recently overhauled at the time. So it was a strong performer, and a local engine, which could be seen working all manner of passenger and freight.
55019 I adopted after a stunning run on the Up Aberdonian in 1977, when we departed Darlington somewhat late and arrived York on time, having done the 44 mile run in under 30 minutes start to stop, with maximum speeds around 112 mph.
50018 was the only 50 I ever had out of Falmouth on a service train - the Saturdays Only Falmouth - Paddington in 1979, the last year it ran. Subsequently I had some good Resolutions.
As for AC electrics, I liked 87s, but had a particular liking for the 86/1s, which were really 87s in the guise of an 86 (or "Wolf in Sheep's clothing" as they were sometimes known). The subsequent reincarnation of 86101 as a Caledonian Sleepers loco was most welcome.Shame it's finished now. I also had a soft spot for the class 82s, but they were rare and unpredictable, so I couldn't claim any particular favourite loco.
I never chose any particular class 37. There's no such thing as a bad class 37. Conversely there's no such thing as a good class 31. (This thread hasn't exactly been overwhelmed by people proclaiming their love for their favourite 31, has it?).
I heartily despised several specific class 47s. In particular, the specimens which were the first to go through Cost Effective Maintenance (i.e. a main depot overhaul instead of sending it to the works) were utter nightmares. In this Hall of Shame I place 47470, 47478, 47578, and 47595. These leaky spluttering specimens could be guaranteed to fail if they turned up on the train you had to take for a short connection onto something better, or would work perfectly when you wanted them to fail so you could stand a chance of a rescue loco for haulage.
