While many of Toronto's trams are 2-car, several also run as single car units. Here the front panel has been slid back to reveal the coupling mechanism underneath. The network is electrified on 600V dc and runs to a 4' 11" gauge. I could not get any information about the car builders though. (Toronto, Canada, Nov.2015)
