The planned improvements to the service on the Richmond branch currently proposed by CLRL are enabled by investment in other areas of the District line. Capacity in the central area is the current pinch-point to operating improved services to any of the branches. As this investment will continue irrespective of the decision on Crossrail, the Richmond branch would continue to benefit.A moderate improvement to the signalling and track would mean peak scheduled service levels from Richmond would improve from 8.5 minutes to 8 minutes by around 2011.D-stock trains would certainly be refurbished irrespective of the decision on Crossrail. .
