Helenvale Street is still there. The northern end of it comes out onto Tollcross road, a matter of yards from Parkhead Cross. The Parkhead Forge Steelworks, which used to be situated in the Parkhead area, used to employ lots of men until after world war two, and a shopping centre now occupies that position and is named "The Forge" in memory of it. If Andrew Wright was an engineer or fireman and might have worked in a steelworks and was living in either Helenvale St or nearby Camlachie, it is quite possible he was working at the Forge. The old Forge was very large and sprawling, belching lots of smoke from chimney stacks - heavy industry!
.... I remember there was a narrow-guage, single railway line that crossed Duke St just about two hundred yards down from Parkhead cross. If you were going along Duke St up to Parkhead on a tram or a bus, a barrier would sometimes come down right across the main road, and everyone would then watch for the tiny little train crossing the road, from one side of the Forge works to the other. Everyone was familiar with this, and kids loved to see the dainty wee train.
At one time, around the first world war, I think it was, the Forge was the largest steelworks in Scotland employing 20,000 men.
