I was thinking of Dundalk-Drogheda as the first 100mph section as there are far fewer non-revenue/freight movements. I know there are significant challenges especially up north but it would lay down a marker.
Given that the Mark 4 DVT is non-revenue, can a DVT set operate to both Central and Connolly with 8 revenue coaches properly on the platform, as Enterprise DDs do (albeit with both nonrevenue elements, DVT & loco, at the same end)
