Border Crossings: Poland - Slovakia

(Muszyna -) Leluchów PKP - Čirč ŽSSK (- Plaveč)
[E] The 2024/25 service remains two pairs winter/summer SSuO between Poprad-Tatry and Muszyna worked by ŽSSK that run between 28 December 2024 and 23 February 2024, and 14 June to 14 September 2025.
Serious flood damage washed away a bridge north of Muszyna on 4/5 June 2010 so the line was completely closed until 17 January 2011 but initially only freight traffic resumed. A summer only SSuO passenger service recommenced on 29 June 2019 until 1 September and then a winter SSuO skiing service was added from 28 December 2019 to 23 February 2020 and Covid suspensions excluded, this pattern has continued. PKP also works freight to Plaveč.
