Work to erect overhead electrification cables on the Great Western Main Line has begun.
Network Rail is using a
specially-designed factory train called Brunel which works at night so
trains can keep running during the day.
The train works up to five times faster than conventional gangs of track workers. The
team will work westwards at one mile a night, reaching Oxford, Newbury,
Swindon and eventually Bristol and south Wales at the end of 2016.
Hitachi High Speed Trains have been ordered for the newly electrified line
