One area where increased acceleration will cause additional energy loss is in the resistive losses in the overhead line. If you compare the same train accelerating at one rate with it accelerating at twice the rate (to make the sums simpler) then the harder acceleration will require twice the...

Reading the GA statement :- it struct me that what it did NOT say was that the signalling system was picking up old and new trains EQUALLY well/badly. It could be that although the old trains were being picked up less strongly than Network Rail (NR) would like it was still sufficient for the...
