"DEMONSTRATION BEFORE MUNICIPAL TRAMWAYS CONFERENCE AT WEST HAM. The motive power is drawn from the overhead wires". Two engineers (one in work clothes and the other in smart dress) work on a section of rail observed by members from the Conference. A tram in the background can be seen with the name `Dalton'. Shots of a trackless tram car (more like a single decker bus) travels up and down a street in West Ham. The overhead wires can be seen in some shots as can the overhead arm on the tram. The tram travels along a road which has trams lines. Crowds of people watch the tram and the camera. Other traffic also passes, including a car and a horse cart.
