They could just operate at all times in "series" - 375 volts across each
motor - they would probably be speed-restricted anyway. Only problem might
be whether the insulation can stand the continuous application of 25 %
higher voltage. And there is the problem of fitting them with pantographs,
or ensuring the overhead can cope with trolleypoles. Anyone know about the
latter - points would be the main problem. But they've done it in Melbourne!
(i.e operated trolley-pole trams on the 'light rail lines', which are set up
for pantos only.)
