This is one of my favourite Loco’s that my dad has, when i was younger i was fascinated by the smaller wheels that the 8F locohad. It would pull and pull all day it could be laden down with a good 10 petrol tankers and still pull well.
Since the track was only laid down once or twice a year this is one of those locos that started of slow and needing warming up on first run and then it would be fine.
In my memory i think its been re magnetised once, they main issue is the solder gets weak that connectors the power tender to the loco and this often snapped.
I can’t remeber when or where my dad bought this loco or even how much it cost. but its still one of the best he has.
