Lansdowne Road DART Station in Dublin will close temporarily during an international match next month as part of a trial run ahead of Euro 2020.
It will be shut between 5:30pm and 11pm for the Ireland v Denmark Euro qualifier match on Monday November 18th.
The exercise is to see how congestion and crowd control would work ahead of the four Euro 2020 matches at the Aviva Stadium next summer.
DART services will continue as scheduled during the trial, but passengers will have to disembark at either Grand Canal Dock or Sandymount DART Station during the closure.
The trail has been agreed by the FAI, local authorities and the Department of Transport, Tourism and Sport - with gardaí, Irish Rail and the National Transport Authority (NTA) supporting the effort.
According to the FAI, the Euro 2020 games in Dublin are set to bring a lot of supporters to the city - including some without tickets.
Officials are hoping that the access changes will "prevent ticketless supporters accessing the inner cordon of the stadium".
Cathal Dervan, FAI director of communications, explained: "The matches at Euro 2020 will have different profiles, requirements, mobility patterns, and ticketing systems to a normal game at Aviva Stadium.
"Ireland has never hosted an international event of this magnitude before and we are testing additional stadium access, mobility, safety and security measures, one of which is the temporary closure of the Lansdowne Road DART/train station.
"Following this trial, a joint review will be undertaken in advance of Euro 2020."
Euro 2020 is being hosted across 12 different host cities, with Dublin set for three group games and one round of 16 match.
