Not wishing to doubt you, but did they really place an order?
I seem to remeber them (Northern) flying a kite about what might be available from China, but actually placing an order is a lengthy process that would have taken months.
I dare say parties of Chinese engineers would have been visible at Newton Heath running rulers over the existing rolling stock.
It is interesting to note by way of contrast that Hitachi were seen around the UK▸ railway for a couple of years before an order was announced.
Northern Rail decided on the length of the carriages (longer than 142s or 150s), that they would have 2+2 seating and that there would be a mixture of 2 and 3 car units built. The
DfT» made it clear that trains for use in Britain can not be built outside the
EU» , so blocked the proposals. I don't know exactly what stage the order was at when DfT blocked the proposals.
It was assumed at this stage that Northern Rail could get the majority of the 158s released from TP Express (when the 185s were released) and some from Central Trains (when the 350s were put on the Liverpool to Birmingham route, displacing some 170s, which in turn would have released 158s) meaning that most 142s would have been out of use by 2006, which obviously didn't happen. Part of the problem was the order of 185s being reduced meaning a number of 158s had to go to South West Trains in exchange for 170s. (170s were deemed better for the Manchester to Hull route than 158s or 185s due to weight problems on the line.)
So in 2004 the order being cut didn't seem too significant as it was assumed that around 50 142s would be removed from service by 2007, not 12 which would later be put back in to service with First Great Western.
