Just to be clear, I wasn't arguing for air conditioning to be
fitted, but I still think you are mis-estimating the effect of
regeneration on the total energy consumption and heating for the
new trains. The whole point of regeneration is to reuse the energy
which used to be 'wasted' in resistor banks on the trains (with the
original rheostatic train brakes). My understanding is that little
of the recovered energy goes back to the lineside equipment, if the
current rails are not receptive, then the spare energy goes to
resistors, like in older stock. The extra big lineside equipment is
purely because more current is needed in the first place.
What happened to the test of trackside rotating cylinders designed to
store the energy from regenerative braking?
That was just spin.
ROFSE!
