That's GBP1-1.5m per train, or GBP150-200k per carriage. Doesn't
sounds a million miles out...
For a couple of electric motors!!!!
About 10% of the cost of a new carriage to replace the whole drive
system? Sounds pretty reasonable to me...
Why "the whole drive system" ? I still think GBP50K for an electric
motor is a bit steep.
You can't run AC motors using electronics designed for a DC system.
Though why they feel the need to change the traction package on
perfectly servicable still fairly new trains is another matter. I
can't imagine them saving 100M in electricity bills before thr trains
are life expired.
