The order for extra cars for strengthening ICR sets makes a lot of sense. However given the cancellation of the 2700 and the 201 loco projects, I would not count the chickens yet.
The intention to order 480 vehicles from 2023 onwards begs a large question: the extent of intended new electrification. Maynooth looks fairly certain and also perhaps Connolly to Hazlehatch. What about the line to Pace? What about the Northern line to Balbriggan, or Drogheda?
More important the sheer numbers of vehicles would imply something much more radical: intercity electrification (probably 25kv, necessitating dual voltage capability).
Given ambitions to go over to electric cars, surely railways are much more amenable to electrification. Do we have any coherent and detailed plans for all of this?
