You might see from some other posts that there have been a couple of muggings (not a large number, but enough) around the alleyway between Sunderland Rd and the top of Trilby Road. You'd probably want to be careful walking alone along this unsighted alleyway after dark (the problem is you can't see what is at the end) and then you can do as we/others do and stick to the south circular/Stanstead Road approach (or go along Perry Vale) - depending on where you are it is probably a couple of minutes extra. We're in the same area. I walk home from the station most nights and it isn't a problem.
