There are two train stations in the city: the north one and the largest, Iași Railway Station, which serves internal routes from and to other cities in Romania, and the southern one, the International Railway Station, which also serves international routes to and from Iași.
For all routes, you can either buy tickets directly inside the train stations or online. For internal routes, trains are much more frequent and you can purchase tickets here. If you’re traveling to Iași from abroad, tickets are available here.
From the North Railway station you can take a taxi (as there are many of them right in front of the building), bus or tram. Both transit stations are right outside. Or you can order an Uber or Bolt because the waiting times are usually very small.
