"By 2050 it is expected that the majority of medium-distance passenger transport will be by rail". Thats the reason why the current generation should not make the same mistake as some of the previous political generation in IRE in dismantling rail infrastructure. The ideas that are coming for rail in the future are lighter and greener but having the permanent way in place is a huge advantage which in IRE is already the case like the Western Rail Corridor.
