[article] Iarnrod Eireann urged to reopen tunnel

Personally, I don't think running IC trains through the Interconnector would be practical from an operational viewpoint, since the whole point of the KRP is to give DART a fully segregated line through the city. If IC trains were to use it, they would have to be electrified.

There's no problem for diesel (and let's not forget, it was built for steam trains) using the PPT, as it is a much shorter tunnel, and trains do not stop at stations within the tunnel.

I believe it would be possible to build an Interconnector that could take diesel trains, but it would have to have a lot more ventilation. However, if there is a need to run trains between the Heuston and Connolly networks (for example, a Cork-Belfast service), these should use the Park tunnel.
