Good morning all
Hoping someone can help with solving a problem that I’m having regarding the position of the negative rail.
Now we all [should!] know that L.U. is standard gauge which is 1435mm between the running rails and that the negative traction current rail is always inbetween the two running rails.
The question I’ve got, is is it in the dead centre I.E. the middle is 717.5mm from each rails, or is it skewed slightly to one side?
I’m guessing there will be some tolerance allowed, but there must be a defined point from which the tolerance can be calculated?
