That's just plain wrong.
There's double track to Glounethaune, with single track for the 10 km to Midleton with a passing loop in Carrigtwohill. Trains can run every 15 minutes with this arrangement.
So they can double even the rush hour frequency. Add to that the ability to put on longer trains and you can have up to 6 times start-up capacity.
Even if it was the wrong decision, it will be a long time before we find out.
