I think that we'll have to agree to disagree here. what's needed on northern/TFW is a super-pacer.not a 195. due to the speed limitations on most lines there is very little requirement for a 40+ tonne per carriage,100mph capable unit with huge engines bombing around rural northumberland with 200 passengers peak load (it's overcrowded!) and 20 passengers off peak.at 2 cars with 150 capacity. there IS a market for a 30 tonne per carriage,85-90 mph capable unit with realistic sized engines(300bhp ish and double the mpg) with 3 cars...it should handle 200 at peak with maybe a couple standing instead of being stranded on a platform. It won't break the bank running it at low load either,especially if they can do eco mode and re-map /isolate the excess engine during times it's not necessary I don't think it's unrealistic at all for double fuel efficiency of the 195's let alone the sprinters,given 30 years of advancement in engine technology.I do think that the capacity and top speed needs improving though, as a lot of lines now have to factor in pathing for a mainline stretch of 100/125mph trains, which is a sizeable increase on the typical 90mph express of the 1980's. sounds like I have contradicted myself in this post ,I know, but a large chunk of rural routes also include a small mainline stretch,so a bit of versatility needs to be built in, just not as much overkill as the 195's do,but more than a present pacer or 150/156 has! (if they could make the 158/159 3 cars about 3m shorter per car,and 7.5t per car lighter,coupled up with a hybrid engine they would be ideal)..basically a turbocharged 150/2!
