Transport experts are divided over whether the new commuter rail system will bring an economic boost or be a burden on local residents.
The Government has said the new route will benefit “every household” but it has faced criticism for the fare hikes.
In the long term, the cost could be borne by local residents, but for now, there are doubts whether the fares will make a big difference to the region.
One of the main criticisms is that the scheme will not make the region more competitive, and will instead be an expensive way of getting people from one part of the country to another.
However, there is evidence that many families will benefit from this new service, and a recent study by the University of Limerick has found that families who travel between the two cities have higher living standards than those who commute to Dublin and Cork.
In 2016, the regional transport authority, the RTE, said it had a study on the impact of the new service on families travelling to Cork.
A report from the Department of Transport found that while the cost of the scheme is high, families who live in the region will be “slightly more prosperous and are less likely to suffer from long-term housing costs”.
It said the increase would be passed on to the regional economy.
But the Department also said that the increased fares would not be passed down to families on the regional side.
“The effect of the fares is passed down the line to the families and the regions’ housing stock, but there will be no impact on the price of housing,” it said.
The report also found that there is “limited evidence” to show that the regional cost of living would be impacted by the fare increases.
However the Rte said that there was “no evidence that the impact on housing prices will be negative”.
Transport Minister Shane Ross said he wanted to make the journey easier for people.
“Our aim is to make it as affordable as possible for people to travel to and from the regions,” he said.
“That is what we are trying to encourage.””
The study by Limerick University found that the increase in the fares for commuters from the Dublin and Limerick regions would cost €9,000 per year per family. “

The study by Limerick University found that the increase in the fares for commuters from the Dublin and Limerick regions would cost €9,000 per year per family.
The study said that, in the long-run, the effect on the region would be minimal, but it would be borne “almost entirely” by families who are in the Dublin region.
However some members of the public have suggested that the fare increase is an unnecessary burden.
One resident, Clare McLeod, said that “a lot of people” would pay more for the journey and that she was “very disappointed” that the price was going to be so high.
She said that she is worried about the impact the extra costs will have on families who do not have the means to pay.
The RTE said the study found that “more than 60% of households in the RTS region would not pay more than €10 per month for the rail service”.
A spokesperson for Limerick City Council said that people would be “likely to pay more per journey” and said the council had no evidence to suggest that families would be less likely “to use it as a means of transport”.
“This will make it more difficult for families to access a wider range of transport services,” the spokesperson said.
However this is not the only region that has been affected by the cost increase.
A study published by the Institute of Public Policy Research in June 2016 found that it would cost the regional authorities up to €50m per year to maintain the rail network.
The research found that regional authorities were likely to be “disadvantaged in terms of funding” due to the costs.
