Whatever anyone thinks of the Civity's they are here to stay. Northern want standardization of the fleet (hallelujah) and the easiest place to start is the EMU fleets. Replacing like for like may be the best start (16 x 4 car to replace the 333's and 34 x 3 car to replace the 323's).
As for standardizing the diesel fleet here are some musings:-
Crayons out
- Can a bi-mode Civity be ordered? (diesel/electric with an option to convert to full electric should the knitting ever go up across the network). This would go a long way to replacing the entire diesel fleet.
- Also could the 195's be converted to bi-mode by extending the units by at least 1 vehicle and converting them from hydraulic transmission to electric.
- The battery idea is good but is still limited. Ideal for the likes of the Windermere branch and Newcastle - Metro Centre and even on routes which are largely off wires but have the range for that section (Leeds - Sheffield via Moorthorpe etc. as mentioned above for instance).
- Could a rural fleet of 3 car Civity diesel/electric bi-modes be produced internally fitted with either a better layout or if it were possible be based on the class 397 body with a class 331 style cab and still be able to work in multiple with the core fleet.
Crayons back in the box!
The above are all hypothetical questions and could be a possible way around standardizing the fleet and more importantly keeping it as green as is possible. Pure diesel has had its day and should have gone a long time ago.
Of course cost would be an issue but large orders generally garner more favourable rates as with everything in life.
I'm inclined to think that the simplicity of standardising on an entirely 3-car CAF fleet, run singly or as pairs, would have a considerable benefit.
If, for example, you could have everything on Castlefield running in that manner, you could mark door positions or even have pseudo-platform edge door fences which would help control the baying mob.
Basing the entire fleet around a short section of track in Manchester is daft. The North is so much more than that.
Adding 4 car units and even 5 car units into this would allow a much more flexible formation across the whole network so long as every service was diagrammed correctly.
