After a wait in South West Sidings to allow another train to pass, 66719 takes the curve through Willesden Junction towards Mitre Bridge Junction with the 6O72 Colnbrook to Grain aggregates empties. The main line to Euston curves away to the left with the BT Tower on the horizon. The trains just visible through the catenary on the left are parked up in Willesden Traction Maintenance Depot.  Another grey day in north-west London with the rain imminent.
