L16 passes Neasden South Junction working train 546, an 0122 Ruislip Depot to West Hampstead via Harrow-on-the-Hill engineer's
train. Unusually, this worksite required possession trains to come alongside the northbound Metropolitan Line on the up 'Chiltern' Line,
hence why this train is running along Network Rail metals rather than on Underground metals.
