I've never understood public transport undertakings buyingRemember that these trams were built in the 1920s, a very different era from today. The H type were built in 1929 for a converted rail line with good patronage. They needed the capacity at the time, hence their size (64 seated, 170 crush load, capable of running in multiple sets). And steel was becoming more available and more popular than wood, hence the weight (23.1 tons). Most of the line was on reserved track, meaning faster travel was safe, hence 4x60hp motors. They were quite suitable when they were designed.
needlessly heavy vehicles. There's no way the H class needed to
weigh more than 20 short tons and it probably could have weighed
significantly less and achieved good performance with smaller
motors.

How long is your running track, Peter? Is it all single track? AnyI don't have an exact figure for the length of the track, but it is in the order of 2km. I'll scan the layout map and put it on the web site in the near future. We have a 5 track depot fan merging to a single track run with an automatic (sprung points) passing loop about 60% of the way along. I'll have to check on the length of the passing loop. It know can handle two trams provided one is a four wheeler. There is one stop along the route, at the St Kilda Adventure Playground, at about 90%. The terminus is at "St Kilda Beach", which is nothing like the Melbourne version :-).
passing loops? Is there room for expansion?
