A few not being used today again. Just sitting outside Longsight just before midday today. A daily occurrence now. You sense it's only a matter of time before they begin to be returned to Porterbrook.
I suspect when we get to 2020/21 and the 37 four-coach 350 Desiros are returned to Porterbrook, they might offer Northern a like-for-like deal so they can exchange the remaining 319s they have four years early. There isn't a great deal of demand for eighty-seven 350 Desiros down south. It would ensure a return on the 350s as they only 10 years old, whereas the 319s are now over 30 years old and you sense the grim reaper of the train world is sharpening his scythe.
As an addendum point, the 350s are far more suited to the longer distance inter-city network of services Northern are aspiring to create, particularly on the Liverpool to Crewe via Manchester Airport with inter-city seating layout, racks for luggage and faster acceleration. At the moment, the 319s as commuter trains on inter-city services aren't cutting it. If they persist with the dated 319s I see very little passenger growth in the North West over the coming decade. If they invest in decent, modern EMUs then patronage will increase.
