Many tram systems built in the earlier yaers of the 20th century had lines that extended well beyond the limits of housing and industry at the time of construction.
Sometimes these were built to develop new areas, sometimes to serve recreational locations, and sometimes to serve burial grounds!
In an era when the socially approved Sunday activity was listening to the local preacher (something that I still find rewarding), shops, sports and commercial entertainment were usually not available on the Sabbath.
One option was a visit to the cemetery to pay your respects to the forebears, and Launceston's Carr Villa line was built to serve that traffic.
Mal Rowe - noting that the trams and the cemetery were both City Council enterprises.
