Resumen
The idea of developing sustainable transport in Europe promotes ecological forms of transport. One of such solutions is the transport of trailers and trucks in rail traffic.

Increasing the competitiveness of intermodal transport, in particular the transport of trailers and trucks in Poland, may take place through a series of activities of an investment and administrative nature by the infrastructure manager of PKP PLK S.A. and of a legal nature by the authorities of the country.
