Sighthill East only had railways and grass wasteland around it. Can't remember how I got there. It was the junction for St Rollox works or Sighthill loops
Mention of Sighthill East box brought to mind a similar 'isolated' case in the Salford/Manchester area at Brindle Heath Junction.
Brindle Heath box wasn't necessary isolated in the out-of-the-way or hard-to-access way - more in the sense of being located in a psychologically hostile and vulnerable environment for staff who had to work there.
As with
@cadder toad's example, Brindle Heath Junction at one time had been in the middle of a busy railway environment, with an adjacent steam MPD, plenty of goods sidings, controlling lots of signalling ironmongery, plus with the Atherton fast lines flyover nearby.
In the box's later years, most of that infrastructure was dismantled, leaving the signal box controlling a simple two-track junction and stuck squarely in the middle of lots of vacant railway land, encroaching vegetation all around, and a somewhat notorious 'socially troubled' district of Salford just beyond the railway boundary. See, for example,
this link, dated 1973.
I've read accounts of the poor bobby at Brindle Heath, working alone in his dimly-lit, elevated perch late at night, having the windows pelted with lumps of ballast by gangs of the local 'yoof' who were lurking unseen in the surrounding darkness. This may have been one of those boxes which was manned 24/7, despite having no rail traffic during night-time hours or at weekends, simply to avoid severe vandalism.
Brindle Heath Junction closed on 10th May 1987 when the Agecroft Jn connecting line was closed and the route between Windsor Bridge and Walkden signal boxes was converted from absolute block to track circuit block. The redundant box immediately became a magnet for vandals who had set it on fire by the end of that month.
