We are continuing to carry out ground investigation work along the Chiltern line from West Ruislip. We will be working at two locations next to the railway, one near the River Pinn and the other at West Ruislip Bridge.
As this work is taking place on operational railway property we have to do the work at night when no trains are running. For more information on these works please see our notice sent to residents here .
