In Limehouse in east London, the bridge over Commercial Road near the T-junction of Lowell Street. The bridge is maintained and painted and looks immaculate but can never be used again because new buildings block the route. I don't know why the bridge is maintained so diligently instead of being dismantled and removed.
That's puzzled me for years, as the viaduct leading to the bridge was severed at one point a long time ago, and more bits of it have been removed over the years. I don't know when the east curve at Stepney East (Limehouse) fell out of use, but it must have been 40 years ago if not more. There's no way that it could be brought back into railway use without the demolition of several recently-built buildings (not that there's much purpose in having a physical connection between the line to Fenchurch Street and the Docklands Light Railway).
Is there any chance of the rail connection off the West London Line to the scrapyard near Willesden Junction being used again? The last time I saw it, a few months back, there was shredded scrap all over the sidings.
Has anybody used the rail depot at Keresley, near Coventry, in recent years?
