Delays happens, thats life. The risk of a delay when a steam train is around is vastly more
1. They breakdown, vastly more often per mile operated
2. They get stuck, steam/coal issues
3. They trip the hot axle box detectors
The very least we should expect a diesel locomotive to be dragged along as insurance if something goes wrong.
This is the land of transparency, will Irish Rail apply the network access statement charges and charge for the full cost of the rescue locomotive and the delay minutes, doubt it. Will Irish Rail charge for the siding space in Inchicore etc.
The fare paying passenger should not be contributing a single cent here, nor should the NTA
