A TRAIN service will come under the control of the Mayor of London tomorrow morning.

The North London Railway, currently run by Silverlink, will be taken over by Transport for London as part of plans to amalgamate underground and overground services.

The launch party for London Overground will be tomorrow at Hampstead Heath Station at 10am.

It will go through Wembley Central, North Wembley, South Kenton, Kenton, Harrow and Wealdstone, Headstone Lane and Hatch End.
