There can be all sorts of fantasy solutions at Limerick Junction. The ideal is something that looks like Amsterdam Sloterdijk, with lines being grade-separated and platforms that can incorporate trains to every one of Dublin, Cork, Limerick and Waterford at the same time, with all being a through train from one of the others.

However, that has to be offset by some reality. Every solution has a price that it needs to justify and then there will also be the thought of the future of the line. That means that priority will go to Dublin-Cork improvements, then to Limerick improvements, and then finally Waterford improvements.

I would say, let the Cork-Dublin platforms be built.

Then persuade Irish Rail that Waterford will definitely stay open and needs investment.

Then it may be possible to consider a short platform, linked to the Cork-bound platform, alongside the line to Waterford.

Others on here will know better the operational problems with stopping a train in a location where it is about to cross another track, but I would suspect that it would have to be stopped at the platform before any Cork-Dublin or Dublin-Cork services have pulled in. The Limerick bay doesn't suffer from this and it could be possible to put in a terminating platforn off the Waterford line, but that would preclude through running without manoeuvres.
