You are spot on with the answer I wanted Dek.
The Motor Bus shelter pictured here that stood outside the Co-op store was for the cross town Thompson Avenue route from Claregate. (No.14 I believe)
I would catch the returning bus sometimes from the stop in Vicarage Road (opposite Maxwell Road ) after a day at St Josephs School.
I can’t recall a bus going down Steelhouse Lane in the late 1940’s though, when I started at St Josephs our alternative was the Bilston bus from outside Weddell’s in Victoria Square, hopping off at the Horse & Jockey ,and racing (always late) up Steelhouse Lane.
Thank you and keep following…..
