Without knowing the details, one might be forgiven for wondering if investment might have been better spent on track and signalling infrastructure back in 2007-2012 rather than an entire fleet of new rolling stock (i.e. ICRs), when the mk3s could have been operated for another 10 years (i.e. overhauled like UK fleets) and a dozen youngish 201s seem to be rusting away unused in sidings.
There is no doubt the new ICRs must have brought operational cost savings due to track rationalisation, reduced man power, turnaround times, reliability, etc, but there was a very substantial capital cost which may or may not earn enough cost savings over time, especially if the track and signalling has a backlog of maintenance and upgrades due.
Combine that with our new motorway network, then it does look rather bleak for some rail routes.
