at 5:00 you mention considering using heat from the motor for inside the tram. i think ozone is created at electrical contact points so not a good idea for not just reasons of dust. on the other hand there might be a heat exchanger that could make the heat useful. 12:50, just like randwick. were melbourne trams taken to sydney to be scrapped? 17:17, i was also thinking how pissweak the bodies were. just like trabants. fascinating stuff.
Yes, heat from starting/braking resistances was a ‘free’ form of heating. Until the modern tram era in Australia, trams were not heated and passengers just had to suffer the cold which generally was nowhere near as cold as Europe.
@@kevinschroder322 Hi. I will have to check again how it ends, but you may be able to help get a lot more Leipzig video from those days onto TH-cam. I have plenty more to publish, but need somebody with local knowledge who can identify locations. Would you be prepared to give it a try?
Well the scrapping of the spare Tatra cars would have counted as something extra besides just the controller maintenance. Something which I am pretty certain that I have is video of the very last staff car to operate from the workshops to take workers home at the end of the day.
@@tressteleg1 Sounds very interesting. I filmed a lot in Leipzig 20 years ago. I have these videos in my online shop. The name is World of trams. I also have a channel here on TH-cam (worldoftrams) with the respective trailers.
Looks like the ALLEN WEST "VAMBAC" controller used in the Blackpool Coronation cars. These used a Paxolin tube as the frame, and an arm with two magnets to operate the contacts. Burnt contacts and unreliabilty meant the cars were soon scrapped or converted to normal control from scrapped older still cars. The contacts were too big, and tended to burn, and the resistor grids would then overheat and go open circuit. Absolute junk. Have a look at SALVAGE SQUAD, TRAM, on here, and you'll see them try to get the last one, now number 304 in the fleet. The contact had burned closed circuit on that, cooking the resistors and setting fire to the Paxolin. Blackpool cars had a joystick type gear stick - like controller handle. Pull it one way, it'd motor, push the other, rheostatic braking came in. These too had resilient wheels. They weren't fitted with blowers either. I once saw a pic of an American Pennsylvania RailRoad "Pioneer III" EMU car. Like the Vambacs, this too had right-angle drives, and puny motors. Two were preserved, but were later scrapped.

Czechoslovak T3SU/T3SUCS trams actually used the excess heat from the controller to heat the passenger compartment.

Part II ?
@@kevinschroder322 That is all I took of the rebuilding process. Was there something else you expected to see?
@@tressteleg1 The ending gives the impression that there will be a second part. Best regards from Leipzig.

Nice to see you comment again after quite a break, R.H. Interesting info on the Vambac controllers which will interest some people I know. Thanks.
