SUW 2000

SUW 2000 is a type of variable gauge system that allows a train to travel across a railway break-of-gauge.

The SUW 2000 design is manufactured by Polish company ZNTK Poznań for Polish State Railways (PKP). It is used at three border stations, enabling trains to Lithuania, Belarus and Ukraine to proceed without the need for lengthy bogie exchange.

Similar, but incompatible, systems are produced by Talgo (Talgo-RD) and Construcciones y Auxiliar de Ferrocarriles (CAF-BRAVA). The SUW 2000 is interoperable only with the German Rafil Type V systems (built by the Radsatzfabrik Ilsenburg).[1]

As of February 2007, a single SUW 2000 bogie cost the equivalent of $42,000.[2]

Routes

The following interchange and break-of-gauge locations were fitted with a SUW 2000-compatible track gauge changing facility, allowing trains crossing those routes to be fitted for gauge-changing, rather than bogie-replacement:

Installed 1,435 mm (4 ft 8 1⁄2 in) - 1,520 mm (4 ft 11 27⁄32 in)

The SUW 2000 method of variable gauge system was designed by Ryszard Suwalski.[6]

gollark: No they don't. Just guess.
gollark: Some of them are basically just static images which do not change per-visit, so they probably aren't.
gollark: I think generally they're required to say so, or come from some terrible company like Google.
gollark: REALER men connect the Ethernet cable to a really fast LED and some switches.

These axles are required for replacement during the maintenance inspection and during the exploitation in case of defects, as production of one wheel-gauge usually takes 6 months. The price of acquisition of one SUW 2000 amounts to about 115 thous. Lt. The total sum, needed for acquisition of wheel-gauges, would make up 0,92 mill. Lt
