I don't think that's been the case since May 2018. The Morecambe shuttle starts and ends its day at Blackpool and is in a cycle with Ormskirk/Colne/Blackpool South diagrams. So Newton Heath units. Cumbria is still Heaton units as far as I know.I believe that the Morecambe branch services, alongside the Cumbrian coast services are worked by Heaton based units, however, Heaton no longer has any Pacers and the returning Pacers will be based out of Newton Heath.
Never a 150. Barrow crew don't sign them.That’ll explain why the shuttle was a 156/150 most of the time early this year.
