This update covers a couple of shifts of work, all shown in the photos below. The compressor mountings have been welded in after plenty of iterative design changes. The compressors and the stand which supports the top compressor are direct from the donor loco with a couple of minor alterations to suit the revised location. The block one of the door to the cab from the engine room (former radiator corridor actually) but this makes no material difference as the new way into the engine room is through the middle door (formerly into the radiator fan compartment).
