The RSC would have sign off as a whole different set of engineering rules apply above 165kph

On paper Mk4 stock is the only be design allowed to 200kph. The track relay on the Dublin Cork is/should be 200kph spec

Long held investment plan was for 200kph and this sounds like a putting it out there for funding

Reasonably light 200kph locomotives are now possible.

You might be able to squeeze the ICR to 175kph through an approvals process (like the 110mph Siemens class 350 in the UK) but beyond that it lacks the power to weight ratio for sustained 200kph running
