The first of Great Western Railway's (GWR) new high speed trains failed to run on time this morning due to a train fault.
The Hitachi train was meant to carry passengers from Bristol to London Paddington this morning at 6am, but left 26 minutes late.
Our reporter on scene was told staff had difficulty coupling the carriages.
93 new Intercity Express Trains are expected to replace GWR's existing services by the end of 2019.
The upgrade project was reported to have been delayed and over-budget, but the new trains are expected to ease overcrowding.
