I went to a Northern event today for invited stakeholders concerning new and refurbished trains. It was presented by the Head of New Build and the Head of Train Refurbishment.
Some of this is not strictly relevant to this forum, but is included for interest.
Concerning corrosion, class 150 and 155 are the worst, with 155s more a problem because the Leyland drawings no longer exist. 158/319 are generally OK. I don't remember 156s being mentioned, but I think they are also OK.
Corrosion is the responsibility of the ROSCOs, and most of the delay has been caused by the need to determine extent, negotiate contracts for rectification with a view to a further 10 year life, and to do the work.
150276 has got an entirely new roof.
The seats for the new trains have been decided. On being asked if they would be thick and soft, the answer I thought was evasive, and although assured they would be comfortable, they seemed from photographs to be slightly more padded ironing boards. We will see.
156 & 158 are to get these new seats.
150s are to get seats refurbished to the new style. Some seats ex 156s are to be refurbished in that style and put into 150s.
150142 is to go to Crewe next week and will be the first to receive the new style refurbished seats. The next 155 will also get these.
Luggage space on 156/158 to be increased.
150s ex LM & GW will arrive Dec 17 to Feb 18. Earlier work should mean they do not have corrosion issues.
12 150/1s are to be converted to 3 car by the addition of a coach ex 150/2.
8 158s ex Scotrail to begin to arrive Jan 18
16 170s ex Scotrail to arrive from Feb 18, the first ones to Leeds. Later will work Leeds - Southport/Chester.
11 769s on order instead of 8. First to be tested on the GCR in Feb 18, then to Allerton. Expected use on Stalybridge-Southport, Barrow and Windermere services.
156s to transfer from Allerton to Newton Heath.
158s with Perkins engines to go to Heaton for the Carlisle service.
The first of the 98 new trains will be factory tested in Nov/Dec 17, track tested at Velim Jan-Mar 18, UK testing Jun-Oct 18, into service from Dec 18. All have 2+2 seating and A/C. The diesels will have 750hp MTU engines.
Any of this could of course change and it was made clear to us that route allocation of types of stock is far from decided.
The impression given is that these events are now being managed by very keen and experienced staff.
