Yes, virtually all passenger trains in Poland are equipped with toilets, though the quality and style vary significantly based on the type of service. On the high-speed EIP (Pendolino) and the modern EIC and IC (InterCity) trains operated by PKP Intercity, you will find modern, vacuum-style toilets that are generally clean and well-maintained, equipped with liquid soap, paper towels, and baby changing tables. On the older "TLK" (Twoje Linie Kolejowe) budget long-distance trains, the toilets are often older "gravity" styles that empty directly onto the tracks (meaning you are strictly forbidden from using them while the train is stopped at a station). Local regional trains (Polregio or Koleje Mazowieckie) also feature toilets, though they may be more basic. In 2026, Poland has invested heavily in "Newag" and "Pesa" modern rolling stock, so most travelers will experience clean facilities. It is always a good idea to carry a small pack of tissues or hand sanitizer just in case, especially on longer journeys through rural areas. Unlike some European stations that charge a fee for restrooms, the toilets on board Polish trains are always free of charge for passengers to use throughout the duration of their journey.
