Crossrail train extensions?

With regards to the Greenford shuttle once crossrail is up and running it might not have much of a effect on passengers numbers since a lot of people do seem to be traveling into central London  so chaging at West Ealing might be more attractive instead of changing @ Paddington.

I do personally think the greenford branch should be wired along with the other thames valley branches and a 2 or 3 carriage emu deployed  to work the shuttles.

This would free up a few additional class 165's which could possibly be cleared elsewhere providing they can be cleared on certain stretches of line such as around the Trowbridge area.

Something else I wanted to raise regarding crossrail is  possibility of Henley on thames loosing direct trains to Paddington during the peaks once crossrail is operational,the concern I have is that will some people be put off using the branch trains if they dont go direct to London?

I don't think that the Greenford services should be withdrawn.  In fact I could see the shuttle service becoming quite popular, certainly popular enough to warrant a 2-car Turbo in the peaks. With direct Crossrail connections from central and east London to West Ealing being speedier than the Central Line, and with a shuttle service from West Ealing to Greenford then a 20-minute interval service could operate with two units (increasing to every 15-minutes during the peak if they can be timed to connect well), rather than the 30-minute interval through service at the moment. 

The journey time would compare well from Canary Wharf with whatever you could achieve by using the Central Line (for example 38 minutes is allowed for a journey on the Central Line from Liverpool Street to Greenford, and of course the density of housing in by Drayton Green and Castle Bar Park means there are no shortage of folk living by those stations and nowhere near to the Central Line stop at Greenford.
