During work in the next few weeks on the Clapham Junction branch of the Overground the short stretch from Wandsworth Road to/from Clapham Junction will be replaced by being terminated at Battersea Park instead. May be worth checking out, on the other hand maybe not. CJB.

Looking at the forthcoming track closures PDF, I presume the Wandsworth Road to Battersea Park diversion would be on Sunday 28 July 2013 and Sunday 10 November 2013.
The forthcoming track closures PDF also suggests a possible diversion from Kilburn High Road via Primrose Hill to Camden Road (instead of Euston) on Sunday 09 June 2013, Saturday 15 June 2013 from 19:15, Saturday 09 November 2013 from 19:15, and Sunday 10 November 2013 until 12:00 and after 21:00, unless the plan is simply to terminate southbound Watford Junction to Euston trains at Kilburn High Road.
