RE: Northern Rail
Short forming means the service will have less coaches than it is supposed to have, so instead of being 4 coaches it will be 2, for example.

As a result of the incident at Allerton, there were three less class 319's in service than there would normally be, so their diagrams would be covered by a DMU. As there is very little spare, that DMU will have been found by borrowing a DMU from a diagram operated by two units.

This also causes other issues such as making sure the DMU gets to a fuel point at some stage, as an EMU doesn't need to.

Allerton is also home to the North West's class 156 fleet, which operate far and wide, so an incident at Allerton could have repercussions as far away as Carlisle for instance.
