A second branch line in south west England has no trains today because of unscheduled engineering work. Trains between Exeter St Davids and Barnstaple have been replaced by ‘limited’ road transport, according to National Rail, while there will be no trains between Par and Newquay until after the weekend, because work to commission new signalling has overrun.

The first three of 54 new trains being built by CAF for the Docklands Light Railway have been withdrawn. Transport for London said there had been ‘an issue with braking performance during wet weather on one train’. The introduction of the B23s was delayed for over a year, because of difficulties in achieving compatability with the DLR’s control system.
