Class 313 EMUs to preservation on retirement?

[roythebus1]

Think about it logically, the 313 is a 3 car unit, motor coach at each end. Not a problem on 3rd rail, pick up shoes on the outer end of outer bogies. The transformer was in the centre coach. So under the overhead, how does 750v get from the transformer to the end coaches? There was a 750v bus line within the unit. There's no 25kv bus line as there is no need for one.

 

You may be confusing the unit bus line with the old style 4SUB bus line which was provided between units.

 

I know how old the 313s are, I was secondman at Kings Cross during the time the Northern City Line was being converted and later drove 508s at Waterloo.
