That Eolas piece appears to have been written by Irish Rail! I'd have liked some critical analysis rather than a IE press piece.
There are new trains allegedly on the way - in a few years. Our government knows that rail investment is needed, but is doing everything it can to kick the can down the road.
If we know that new trains are coming, and that electrification will be the future, why not start work on the electrification of the Maynooth, Kildare and Drogheda lines now? Some of the new trains will be dual mode diesel/electric, but the sooner electrification starts, the more rail can contribute to emissions reduction. Does it make any sense to delay the project till new rolling stock arrives?
