For the benefit of forum members, I have quoted the article in question:
Is it normal for the original builder of the train to contribute to the refurbishment of a second hand unit?The investment comes from Siemens, which built the trains, and Porterbrook which owns them.
Or is is this because the Siemens Desiro Verve is likely to be on Northern's candidate list for its upcoming orders?
Or am I being overly sceptical?
