Hi Lyn.
The onlt reference I can find for Wheeler Street & Great Hampton Row these lines was opened on the 25th Oct. 1886 and were operated by steam trams,leases ran out 1906 and services stopped.
On the 30th June 1911 Birmingham Corparation took te then disused since the withdrawal of steam trams Great Hampton Row line, I don't think it operated again.
Wheeler St to Villa Cross opened on the20th Nov 1912.
Thats all I can find.
