SUW 2000

SUW 2000 is developed in the centers ZNTK Poznań for Polskie Koleje Państwowe an early 1990s Umspurtechnik, with the specially adapted to this Umspuranlage wheel sets the type SUW 2000 can automatically change gauges of rail vehicles.

The gauging is necessary where two railway networks or stretch to meet with different track gauges. If rail vehicles to pass from one to the other network, a number of precautions must be taken, the most evident is the adjustment of the drive.

As the countries east of Poland use a different gauge, the engineer Ryszard Suwalski developed the automatic Umspursystem SUW 2000. Thus at times direct trains were equipped to Lithuania and Ukraine, which brought together a large time savings.

Here, the wheel discs are unlocked on the rigid axle, moved into the respective end position and then locked again. This process may, depending on the type of Umspuranlage in both wheel discs of a wheelset occur simultaneously (symmetrical system ) or firstly at the wheel discs one and then made ​​the other side ( asymmetric unit). Asymmetric systems require a longer distance for the Umspurung as symmetric systems.

The lane change is completed during the slow ride through the plant. When driving the system with about 15 km / h, opened by actuation of the release mechanism of the chassis rails, so that the wheel disks of guide rails can be adjusted to the new track.

When Umspursystem Talgo, the vehicles are worn during the Umspurvorgangs of side-mounted slide rails so that the wheels are relieved during the Umspurvorgangs. Thus, the wheels do not aufklettern on the rails during the adjustment of the gauge, the gauge may be changed only slowly in these systems. The equipment for the systems SUW 2000 are longer than the Talgo gauge changeover system, since the wheel discs are moved under load and therefore the ratio of track change has to be smaller to Umspurstrecke.
