London mayor pressing ministers on 鈥榰nacceptable鈥 use of London Overground to connect to HS2

London mayor Boris Johnson has called on transport secretary Justine Greening to look again at proposals to use the capital鈥檚 rail network to link the High Speed 1 line (HS1) with the proposed HS2 route.

At a meeting in February, London Assembly member Navin Shah raised concerns over the effect on London Overground services posed by a junction involving the North London Line in the Camden Town area.

In his recently-published response, Johnson agreed that 鈥渢he proposed connection between HS2 and HS1 is unacceptable and alternative options must be identified that do not adversely impact on London鈥檚 rail services鈥.

Mr Johnson said the proposed link between the HS1, which terminates at St Pancras International, and HS2, which will terminate at Euston, would largely use existing tracks and - under current proposals - would 鈥渁dversely impact on London Overground capacity and performance鈥.

He said: 鈥淚 have asked the secretary of state to consider alternative options which include more dedicated infrastructure for HS2 services.

鈥淚 am pleased that the secretary of state has acknowledged this issue and TfL will work closely with HS2 Ltd to examine all options.鈥

The answer is contained in the updated minutes to the meeting, and can be found in Section 8.
