First Great Western has responded with new adjustments to timetables

Passengers had complained about overcrowding and a group of MPs from the Thames Valley described the situation as "commuter chaos".

Following a protest by hundreds of rail passengers the company apologised "for not meeting their expectations".

The new timetable will come into effect from 26 March.

'Alleviate problems'

Glenda Lamont, from First Great Western, said: "We recognised that some elements of the timetable had not met all our customers needs and we made changes earlier this year.

"I am today announcing further improvements including additional peak time services, extra seating capacity, and modifications to some timings to alleviate the problems experienced by some of our customers."

The changes will affect services in the Thames Valley, Kennet Valley, Oxford, and the Cotswolds.

A company spokesman said more than 750 seats will be added to morning services running through Reading and more than 500 seats would be added to morning services from Newbury.

He added that the changes would improve frequency and capacity from and to Henley, Oxford, Pangbourne, Maidenhead, Twyford, and Worcester.
