Train services between Limerick and Sligo could be reintroduced.
Lobby groups are calling for major upgrades to all railway lines across Ireland.
One of the suggestions includes increasing speeds, so trains can travel up to 125 miles an hour.
The Oireachtas transport committee is meeting today to discuss changes to our railway infrastructure.
One of the other main topics to discuss is extending timetables, ensuring some services run through the night.

When it comes to specific routes, many have called for the Western Rail Corridor to be restored.
The route travels from Limerick to Athenry via Ennis, and then from Collooney to Sligo.
Colman Ó Raghaillaigh from West on Track is one of those asking for the line to be reintroduced.
He says that the regions would reap the 'multiple social, tourism and business' benefits from its revival.
"The route links three city regions, four major hub towns," he said.
"It also affords the possibility of further linking northwards to Letterkenny and Derry."
