Currently used technologies of adjusting rolling stock wheel sets to different track gauge widths in freight transport are very unsatisfactory. Such factors as environmental protection, difficulties in goods transport and a vast area necessary for the process, as well as high costs of reloading equipment must be considered. In case of transport of hazardous materials such as: chemical materials, oil-derivatives and gases, currently used technologies can be a threat to the environment. An original construction of gauge adjustable wheel set - SUW-2000 has been developed in Poland. It can be used in passenger wagons with an axle load of 200 kN/axle and velocity of 100 kph. Basing on the idea, the prototypes of freight bogie cars with gauge adjustable wheel set SUW-2000 II working at higher capacity (axle loads increased to 225 kN) and higher speed (120 kph) with lower tare weight ratio as well as prototype of an automatic new generation track gauge-changing station and transport management and operation of the stations situated at the changing points between 1435 mm and 1520(1524) mm railways were developed in Poland. The above mentioned components are elements of the new technology in freight transport which has been developed in the beginning of the new century in Poland. INTERGAUGE - the new transport technology allows to limit the time required for the train to move through a border crossing with gauge-changing station as well as to minimize environmental hazards. The purpose of the paper is to present scientific problems which were solved during the realization of the project aiming at the development of freight movement technology INTERGAUGE.
