I don't see why it should become National Rail, especially as it's a TfL scheme, rather than a Network Rail one. In fact, the Waterloo and City line was BR, but then came under an official LUL service.
The ELL is going over to NR operation and will be incorporated into a new TfL run franchise for Silverlink Metro. This new franchlise (ELL, NLL Mainline, NLL GOBLIN, WLL and Eus-Wat local) will be assumed on the 11th November 2007.
This will be much like the present arrangements with the Merseyrail system in Liverpool, whereby the PTE specifies the franchise requirements and companies bid for that franchise as per any other rail franchise.
However it is not all bad news as although the ELL is leaving LUL, stations between Harrow & Wealdstone and Watford Junction will rejoin the LUL network as the Bakerloo Line wll be extended back to Watford Junction!! Taking over from the present Euston- Watford all stopper trains run by Silverlink.
"This station is Stratford. Change here for the Jubilee Line, Docklands Light Railway and National Rail services. This is a Central Line train to Woodford via Hainault. Stand clear of the closing doors."
It always is a Woodford via Hainault train... except when you actually want one!
So if the East London Line is going over to NR operation, what rolling stock will run on it? Current Silverlink trains, or the Metropolitan Line "A" stock currently operating on it? Rolling stock can't be shared between the Metropolitan Line and National Rail.
"Four companies - Hitachi, Siemens, Bombardier and Portabrook - have put in bids to supply trains for the East London Line extensions. The first three would build new stock, and Portabrook, an existing rolling stock leasing company which leases trains for use on the national network, would supply existing trains adapted for use on the ELL."
But what we don't know is whether they will be third/fourth rail or if they will use overhead cabling.
