I have recieved some great news in the form of 158840 now being sat inside Crewe LNWR with the ambition to refurbish the interior! Last I heard they were still debating the seating because of lining up with the windows?
Is 840 going to be a test unit to see if all works out? Are they going the full way with the refurbishment or 75% like they have with the 175's?
