Unusual London Overground trips possible this weekend

Due to engineering works on the London Overground this weekend there’s a rare chance to travel over a bit of railway that the trains don’t usually see passengers.
On both Saturday and Sunday 15th-16th July, the usual service between Richmond / Shepherds Bush and Gospel Oak won’t be running. To partially help, they are laying on a special service that will run between Willesden Junction (Low Level) and Stratford calling at Kensal Green, Queens Park, Kilburn High Road, South Hamp
