I started at Hornsey as a cleaner in 1961,there were only two roads inside the shed,1&3? with the other two roads terminated at the entrance..
Both roads had full length pits, but i think they were shorter than steam days holding two diesels on each.and floor area was concreted over its full length.
I cant recollect their being any internal fuelling carried out as the fuel sidings were on the Hornsey Carriage Sidings side of the footbridge.and returning locos usually refuelled on arrival at the shed,
Equipment inside was minimal, i remember a couple of mobile maintenance platforms and water hoses but not a lot else,
Shed staff at that time were a charge hand foreman in charge of labourers and cleaners,and i think two mechanical staff on a day shift who did routine checks,anything else was attended to at Clarence Yard ,they had a cabin at the bottom of number four rd,
The roads number 5-8 were unchanged,
I don't think the building had any doors.
Happy days!
Don.
