But the aluminium trains are heavier and use more power
than their steel predecessors.
The PEP-derivatives (Classes 313-315, 507 and 508) are aluminium
bodied and as light as anything around, though they are quite old now.
But aren't the latest Electrostars much heavier? Of course, they're
air-conditioned, faster, safer and quieter, but exactly the same could
be said of modern vs old cars. And at least some modern cars haven't put
on weight (eg, the Jaguar XJ which I cited).
