Workings on Route 607, 27/04/12

At times when I decide to go northbound via Southall to various places, I use the 607. Today, I found an odd working on it:

 First London VNW32412 (LK04 JBE) on Route 607, Hanwell Broadway (it is an operational spare, I think)

And, a normal working:

First London DN33518 (LK08 FNC) on Route 607, Southall Police Station
