For scenery and efficiency, rail is an excellent way to travel between Slovakia's major towns. The main Bratislava–Košice line slices west to east through the country, via Trenčín, Žilina and Poprad. Buy tickets and seat reservations online or at train-station ticket offices. The fastest domestic trains are Intercity (IC) or Eurocity (EC); SuperCity (SC) are also speedy and modern. Ryclík (R; 'fast' trains) take slightly longer, but run more frequently and cost less. Osobný (Ob) trains are slowest (and cheapest).
