Gday Tony
Assuming arab maintainence, probably a lot
Filing and lubing fingers and segments would have taken place every day
I hope they also had line breakers, which with the controllers
probably had a short unhappy life.
Still, a running tram is better than none
There is no way known Id put the key into neutral after applying 4th
before the tram had stopped
Cheers, Mick
