    4.75 * 25 = 118.75.

    The 4.75 m is in GB pounds per mile. That is €3.5 m per km, or €87.5 for 25 km.

    Indeed I got the decimal point wrong. Edited original post.

    Most structures were altered for OHLE during the dualling. They would likely bundle the level crossing work and the extra EMUs in any figure though.

    Well, if they electrified the line first, and used Dart stock for off-peak and 29000 units for peak, that might get over the initial problem. Perhaps they could go with Dun Loaughrie to Maynooth on 20 minute spacing, with Bray to Malahide on 20 minute spacing, with Howth served by a shuttle. Alternatively, GCD to Maynooth on 20 minute spacing. Alternatively, change the requirement for ALL Darts to stop at ALL stations during peak operation.

    Is it time to start splitting trains live? Say, split the 8 coaches at DL and run 4 coaches to Bray/Greystones. It appears that off peak, 4 coaches would be sufficient.

    We need new thinking.
