Do you know what the linespeed for trolley wire is!!Good point.
If low power, moderate speed, low cost, lightweight 25kVAC overhead is an option for minor lines then a good place to try it out is needed. On such lines freight (if any) would be diesel hauled while passenger trains are electric.
Main line heavy electric trains could use such lines as an alternate route subject to severe power and speed limits.
The Middlewich branch would be another good place to experiment.
It is only used in depots,and slow speed routes.
As stated in many replies on this thread, including mine it is a total WASTE of time, there are many other routes that would come way above this route.
If Morecambe-Lancaster is electrified i will do it in just my hard hat, and will work for nothing.
