South Kerry TD Mr Jackie Healy-Rae has called on the Minister for Public Enterprise, Ms Mary O'Rourke, to deal immediately with "the massive problem of the rail strike" and its effects on the tourist season around the country.
Mr Healy-Rae is also calling on ILDA members to rethink their strike action. He said: "I call on ILDA to have a rethink and realise the massive hurt and damage they are causing to the entire people of this country."
Train drivers' problems can be addressed once they return to work, he added.
A spokesperson for the Minister said Ms O'Rourke is precluded from intervening in the dispute under a high court ruling.
Meanwhile, an action group has been formed in Killarney in a bid to help bring about an end to industrial action by ILDA train drivers.
"We are demanding an immediate meeting with Minister Mary O'Rourke to make it absolutely clear the huge social and commercial catastrophe this strike represents for Killarney and all of Kerry," said Mr Neilie Moriarty, the chairman of the Killarney Rail Action Group.
Getting together a pressure group at the height of a tourist season is a measure of just how badly Killarney is suffering.
"We all feel so helpless about this strike. But we have to do something," Mr Moriarty said. The Killarney group is made up of representatives from the urban council, chamber of commerce, tourist marketing groups, B&Bs and social groups.
Bed nights are being lost to hotels and B&Bs, coach tours are way down, bicycle hire has been cut in half, even the jarveys are way down.
The sick, with hospital appointments in Dublin, are suffering additional anxiety, a meeting on Friday night heard.
The newly elected chairman of Killarney UDC, Mr Sean Counihan, is adamant the 1990 Industrial Relations Act gives Ms O'Rourke the mechanism to sort this dispute out.
"If you dig deep enough into the legislation, essential services including public transport are covered. The Minister can put pressure on."
SIPTU members in hotels and restaurants are being asked to go on short time. "There's a comparison here with Arklow," Mr Counihan said.
"The feeling invariably is Killarney is fine. But Killarney is suffering." Mr Maurice O'Donoghue, an urban councillor, hotelier and a member of the Irish Tourist Board is not surprised the dispute has been allowed to drag on. "This is another clear case of total indifference to what happens in Kerry and the west."
There are deeper worries about the future of rail travel in Kerry if the dispute is allowed to continue indefinitely. Only the main arteries of the Kerry railway remain after widespread closures in the 1950s and 60s.
The Killarney Rail Action Group are asking the three south Kerry TDs including Minister for Justice Mr John O'Donoghue and Mr Jackie Healy-Rae to get behind them.
