Since March of 2016 residents have suffered from a noise problem arising from overnight track maintenance just north of East Finchley station. They have suffered an unprecedented 13 nights broken sleep due to hammering and drilling on this track generally starting at 2 a.m. and lasting till 4 a.m. The work seems to concentrate on the central track - this is neither the northbound nor the southbound track, but a rarely-used track used to turn the trains around. TFL has made no attempt to give residents notice of this work or tell them when it is scheduled to be completed. One resident emailed TFL's Freedom of Information office ([email protected]) on 15th November to try to find out when the work is due to finish, but they have not bothered to reply. Will you look into the issue and give a proper reply as to what has been going on, when this will stop and ensure fair warning is given to residents?
