The 317 motor vehicles cost 12.87p per mile compared to the 13.58p per mile that a 319 motor vehicle costs. The total 317 cost per mile is 27.3p so while removing DC equipment make persuade Network Rail to lower the cost, the difference probably isn't significant.

I asked earlier on if someone could give a typical Northern 323 annual mileage so the difference could be put in to prospective.
In another thread someone talked about 200,000 miles per annum not being untypical for a Northern Pacer (which are less intensively used than the EMUs) so if we say 250,000 miles per annum then a 319 will cost £68,975 in track access charges per annum compared to the £42,950 a 323 would cost. That would mean the difference between Northern getting the 26 x LM 323s and getting 26 x 319s would be £676,650 per annum in track access charges.
OK you might say £676,650 per annum isn't a lot in prospective when Northern have outgoings which are hundreds of millions but when the consultation document was talking about reducing ticket office hours which would probably save a lot less than that it isn't something which should be ignored.
Two comments:
a You are looking at track access charges but what about vehicle lease costs - do, as I suspect, 323s cost more than 319s to lease?
b The LM 323s are there currently under a legally binding lease between LM and the vehicle owners -
i What makes you think, at least without some serious compensation and/or replacement with suitable vehicles (would 319s be any more suitable for West Midlands stations than those in the North?), that LM are going to just release them in order to suit an economically shaky premise?
ii What makes you think the vehicle owners will be content for them going to Northern (which has a dire record for looking after assets) without perhaps receiving a lease premium?
