Crom, I think that picture was taken a long, long time before the Halford's fire. Probably at the time that they put in those traffic islands in front of the fire station, which was brand new, in about 1933. The pic below (postcard I bought in Woollie's, Lozells road about 1951) shows how it was before the building work started.
The tram in the picture was on either the Witton via Six Way route 3 (closed in October 1939 as a war economy measure) or the Perry Barr route 6, which closed on 31 December 1949 (I was on the last tram). I can't believe they relayed the tracks again between 1933 and 1949.
