The mainline sets are very impressive, cost per coach is upwards of 400,000 EUR. The dynamics of the UK market make such expenditure worthwhile. They basically have turned a Mk3 into an Irish Rail Mk4.

Inside the coaches are very similar to the Irish Rail Mk4, the disability access regulations mean the layout more or less has to be the same.
At 250-300,000 EUR per coach IE's overhaul was deemed uneconomic so ICR's were got instead as the cost per km was almost 50% less.

Not sure, for instance, that the cost of operating a six-car railcar from Dublin to Galway would be cheaper than a six-car Mk3 push/pull. Mind you it is fairly academic now as we have a railcar railway with virtually no freight. Not that long ago it was possible to occupy locomotives on an almost 24 hour basis (with obvious operational efficiencies) but there is very little opportunity to gainfully employ railcars between about 2200 and 0600. The current ICR fleet is to a considerable extent a product of the Celtic Tiger era and a fair portion of it was purchased using funds that the NRA couldn't burn up quickly enough. Had the normal rules of economics applied I somehow suspect that Mk3s would still be in traffic, refurbished, and with a good ten to fifteen years of life remaining. I hope the ICRs last the pace and deliver the economies you suggest because it is likely to be a long time before capital is available for replacements.

Its cheaper to operate an ICR, 3, 6 or 9 coaches all good for 100mph, no need for a guard and the fuel consumption per mile is less.
ICR reliability is running at about twice Mk3+201. While the refurbishment looks cheaper, the projected cost to overhaul the Mk3 push pull fleet came to over 25million!

Due safety limitations Mk3 needed 8 coaches to operate at 100mph to make the braking distances.
So while a Mk3+201 is actually fuel efficient when in 8-9 coach length few if any trains in Ireland require such capacity

As regards Mk3 formations there were indeed restrictions on train speed for short formations - can't remember the number but it certainly wasn't as high as you suggest - closer to five vehicles if I recall correctly. |

As someone who reads a lot of their stuff, take anything Metrolinx say with a large pinch of salt or at least look for corroborating studies. These are the guys who stood over a study of 10-12 car EMU trains to replace loco+9/11 duplex trailers+duplex DVT by using conjugated 3-4 car EuroEMUs (Coradia) as a comparator rather than the more similar train consists operated in places like Chicago. (see p29 of this PDF)
