Arriva North West - Birkenhead Depot

RE: Arriva North West - Birkenhead Depot
Arriva have transplanted engines themselves. A St Helens Pulsar also recently visited an external contractor for a new engine though. As has been mentioned, it could quite simply be down to the engineering department being too busy with other work to replace an engine within the required time frame so an external contractor becomes the only choice.
