Meridian exclusively can reveal the Government will announce an order for one billion pounds worth of new Japanese style bullet trains within the next week for First Great Western services in the Thames Valley.
500 new carriages will be built with the first in operation around 2016 or 2017, our Transport Correspondent Mike Pearse understands.
