>>1348231Early years. Freight tram operations started in 1910, passenger tram had existed since 1901. Note the twin trolley poles, I believe this was because of the high currents being used, as the electric system was shared with the passenger tram which used normal trolley poles. Poles were replaced with bow collectors and/or pantographs in 1915, just like on the passenger tram.
