Posted by David Fairthorne on Tue Sep 12 14:18:32 2006, in response to Re: London Overground, posted by Fytton on Tue Sep 12 06:30:51 2006. you are conflicting ... with national rail trainsI agree with you, Fytton, but only if it's essential to segregate the Bakerloo extension from Network Rail. I was assuming that the Bakerloo extension could share tracks with National Rail south of Loughborough Junction, where the Bakerloo would split into two branches each having about 12 tph max. But I admit that it would be quite a squeeze. The flat junction at Herne Hill would have to be grade-separated. There might not be enough capacity via Denmark Hill, in which case you could send more trains via Herne Hill. Beyond Herne Hill and Tulse Hill there is a choice of shared routes. Then of course the power and signalling systems are different. But I don't think those problems are insuperable. It seems to me that whatever they plan for the East London Line extension could, in principle, be done for the Bakerloo extension. Extending the Bakerloo in tunnel would conflict with nothing; but I was looking for a cheaper solution. |
