New trains which were taken out of service after problems hampered their first days in use, have been fixed. They were stopped on Wednesday with issues including water leaking from air conditioning systems on to commuters. On Monday, the first of the four Intercity Express Trains (IET) destined for Wales from London was cancelled. Great Western Railway said the faster and bigger trains, which are designed to run for the next 27 years, are working again after a software upgrade.
Four trains were removed from service on Wednesday due to glitches such as leaking air-con units.
