If you are rebuilding a car to that extent, why are they using
Westinghouse PCC replicas and not a DC chopper drive ?

The chopper drive would be so much more power efficient and need a whole
lot less maintenance.

Other 'heritage' cars have been rebuilt with chopper drives - like
Melbourne's W8 program.
