Last night LU took it upon themselves to work on the tracks just outisde
Harrow on the Hill tube station. They started sometime after 12am and
finished after 3am - our flat faces the track, rendering sleep
impossible etc.

Does LU have any complaints procedure for such cases? Has anyone got any
experience in dealing with them in such cases? Isn't drilling/ sawing/
hammering at such times breaking the law i.e. noise pollution at
unsociable hours?

Any advice greatly appreciated

Isaac
