Former Sheffield Tramway on Google Maps

A Google map I've created shows the routes of the former Sheffield trams about mid-1900s, a decade or so before the system was closed.

The map is based on one found on Wikipedia, plus some old street maps. The main routes should be mostly accurate, though the terminus of each line may be a little out. I didn't have enough information to put depots and stops on the map. If I had that information, along with the actual routes served, then a neat system map would be doable.
