Re: [OT?] PCC controller video

I was the one who guessed Washington. For Montreal, somebody must have regauged the trucks somehow.

The trams did not look too bad at that time, especially the Duwags ex Copenhagen which were then more or less in original condition. The control gear for them would not have been too complex for their workshop staff to maintain.

Unfortunately I have no photos of the K35 type controllers, but if my memory is correct, they were mounted leaning backwards to make it easier for the driver sitting in the PCC seat to reach the handle.

Perhaps most interesting at that time were the double deck/single deck coupled sets, probably both cars powered but the trolley poles were both on the single deck car of each set to have more vertical clearance from the overhead.

Unfortunately getting photos in Egypt at that time was difficult. I think they were still somewhat edgy from the 6 day war which was 8 years earlier.

Photos were almost certainly taken by me ex-wife as I was running the move camera.

January 1975.
