Thanks Tony, that's an interesting paper and (as you have said in the past) charging from overhead wires when available and running on stored energy for short sections of 'no wire' zones make sense.

One small note: Newcastle uses 'super capacitors' as their primary energy storage device.  The trams do have batteries as well but they are not the main energy storage device.

Mal Rowe in a city that just does not notice well designed overhead wires ... but does notice grubby looking trams!
