There you’re seeing the inertia of the planning and procurement system. For an idea of how bad this is, one of the commuter lines will initially be electrified with trains that run on _battery_ for part of their route, because extending overhead lines will take so long. Battery trains have their place on low frequency routes, but the northern commuter line will be every five minutes each way, and battery trains would ordinarily never be economic for that level of service. Diesels will be mostly gone, at least from the city center stations, over the next five to ten years or so, though a couple of intercities will linger on much longer. Ireland has a similar adoption rate of electric cars to France and Germany.
