HS2 Tunnel Boring Machine Supply Cable Works – Update 27th July 2019

Thanks to Cllr Richard Almond, who has attended meetings with representatives from HS2 Ltd., we have been updated about the proposed works through Pinner South to install a high capacity electrical supply cable from the Farm Avenue sub-station to Rushdene Road, and hence on to West Ruislip, to provide the power for the HS2 tunnel boring machine.

The route through Pinner South:

The trial holes along the route for these works will be approximately 1 metre square and will be dug and covered over in one day each in the week beginning 11th August 2019.  In Harrow borough they will be in Farm Avenue by the sub-station, Rayners Lane at the junction with Dukes Avenue, on the bridge over the Yeading Brook in Whittington Way, half way along St. Michael’s Crescent, and in Cannonbury Avenue near the entrance to The Croft.

The main work of trenching for the cable conduits is intended to begin in January 2020.  This work will be done in 50 metre stretches and several will probably be done at the same time with each taking about four days to complete. The trench will be about 1 metre wide and 1.5 metres deep containing a plastic pipe through which 2 cables (1 a back-up) will be pulled when the entire trench is complete.

It is intended to hold drop-in sessions for representatives from HS2 Ltd to discuss these works with residents in Harrow borough, and Cannon Lane Methodist Church Hall is a possible venue for these meetings.   Further information about any meetings will be posted as soon as this is available.
