tram, and in which section of a particular route (North Balwyn). Police then interviewed regular commuters and discovered the identity of a man whom, they believed, had recently travelled to London. This led to the arrest and conviction of the murderer. Decades after the event, the M&MTB were still citing the incident in training courses as a reason for tram conductors, etc., to keep proper and efficient records. In popular culture Tram modelling Model trams are popular in HO scale (1:87) and O scale (1:48 in the US and generally 1:43,5 and 1:45 in Europe and Asia). They are typically powered and will accept plastic figures inside. Common manufacturers are Roco and Lima, with many custom models being made as well. The German firm Hödl and the Austrian Halling specialise in 1:87 scale. In the US, Bachmann Industries is a mass supplier of HO streetcars and kits. Bowser Manufacturing has produced white metal models for over 50 years. There are many boutique vendors offering limited run epoxy and wood models. At the high end are highly detailed brass models which are usually imported from Japan or Korea and can cost in excess of $500. Many of these run on gauge track, which is correct for the representation of (standard gauge) in HO scale as in US and Japan, but incorrect in 4 mm (1:76.2) scale, as it represents . This scale/gauge hybrid is called OO scale. O scale trams are also very popular among tram modellers because the increased size allows for more detail and easier crafting of overhead wiring. In the US these models are usually purchased in epoxy or wood kits and some as brass models. The Saint Petersburg Tram Company produces highly detailed polyurethane non-powered O Scale models from around the world which can easily be powered by trucks from vendors like Q-Car. In the US, one of the best resources for model tram enthusiasts is the East Penn Traction Club of Philadelphia and Trolleyville a website of the Southern California Traction Club. It is thought that the first example of a working model tramcar in the UK built by an amateur for fun was in 1929, when Frank E. Wilson created a replica of London County Council Tramways E class car 444 in 1:16 scale, which he demonstrated at an early Model Engineer Exhibition. Another of his models was London E/1 1800, which was the only
