North Eastern Railway ES1 BO-BO electric loco
The Newcastle Quayside branch was about a mile long and connected the Newcastle Quayside to Trafalgar Yard near Manors East Station. As it had a number of tunnels, making steam operation very difficult, it was decided to electrify the branch when the Tyneside suburban lines had been electrified.
Two Bo-Bo electric locomotives (Nos. 1 & 2) were built to operate the branch in 1905. They operated from overhead wires in the open, but from a 3rd rail in the tunnels as there was limited headroom.
They continued in operation until diesels took over in the late 1950s, and fortunately one loco was saved for preservation, and is now part of the national collection.
Requires chassis, wheels etc
