They'd also need to consider whether to go for a standard DMU order for local routes or to go for a more costly DEMU option which is either dual-powered or can be converted to electric at a later date.
I think there is a very strong case for bi-mode units with the ability to run at 100mph/110mph under 25kV but at a more sedate pace on diesel. There are many regional lines where this capability would be useful.
