So, that's a electrification of the only bits of GW track that are in the South East then? And fuck Wales and the West presumably.
What's basically happening is the southeast bit up to Oxford and Newbury needs electrification because they will be getting the old electric trains from the thameslink area. The thameslink area will be getting a large amount of the new carriages that are being promised.
Wales and the West electrification is basically on hold until they've decided what type of train will replace the HST.
