South West Trains' announcement it's to spend £40 million upgrading its fleet of trains could be a major boost for jobs, says our Transport Correspondant Mike Pearse.
The 455's that run on routes to London will have new motors and electrics fitted to make them more reliable.
Mike said: "The carriages already break down less than any others in the country. They will also have a new system fitted that allows them to use less electricity."
The move will benefit commuters across Weymouth, Bournemouth, Southampton, Portsmouth and Reading.
The work will be carried out at Eastleigh over the next three years and will be paid for by SWT and the Government.
