24 February 2022 became not only the symbolic date of the escalation of the Russian-Ukrainian conflict, but also the beginning of an unprecedented international logistics operation aimed at transporting refugees from the border crossings in Przemyśl and Dorohusk to the entire territory of Poland and to neighboring countries. In a short time, it was necessary to implement extensive organizational activities, including the cooperation of all categories of rail carriers – domestic (long-distance and regional), local government, private and international (from the Czech Republic, Germany, Lithuania, Austria, Switzerland, among others). The coordination of the entire undertaking was entrusted to PKP Intercity, which on the day the conflict broke out established a crisis team responsible for coordinating the transport of refugees using the rolling stock of all available rail operators. These activities were carried out in cooperation with provincial and local government authorities in the country and in agreement with international partners. The involvement of rail infrastructure managers in Poland and neighboring countries was also crucial, which made it possible to maintain the current timetable despite the significant increase in the number of connections launched. In addition to regular passenger transport for refugees, special sanitary and humanitarian connections were also launched – these trains created a transport convoy for the wounded and deliveries of humanitarian aid to the border crossings with Ukraine. In parallel, a rail freight transport operation was launched, including deliveries of humanitarian and military support.
