Transport chiefs plan to link the proposed new Dublin metro with the DART and commuter trains at Tara Street.
It's in a bid to make the line accessible to more passengers in the city.
The Irish Independent says the re-route means a stop at the Mater is now expected to be ditched.
That's despite a station box worth 16 million euro already being built under the hospital.
Dublin Metro is a proposed rail line which will link Swords, the airport with Stephen's Green and Sandyford. A significant portion of the track will be laid underground.
The government has set aside 3 billion euro for it and the final version of the route is expected to be put out to public consultation soon.
If given the go ahead it's due to be read in in 2027.
