To perform a bogie exchange, a car is converted from one gauge to another by removing the bogies or trucks (the chassis containing the wheels and axles of the car), and installing a new bogie with differently spaced wheels.
A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies).

Bogie exchange is a system for operating railway wagons on two or more gauges to overcome difference in the track gauge.
At the border, each carriage is lifted and its bogies are changed.

This method was used at Dry Creek railway station, Adelaide.
First opened in 1856, the station was rebuilt in 1982 and a bogie exchange facility opened when the Adelaide-Crystal Brook line was converted to standard gauge.

SA3 coupler

Also, China and ex-soviet countries use the different type coupler (Janney and SA-3).
Since bogie-changing technology has progressed, this allows for cars with SA-3 coupler to regularly operate on the standard gauge tracks.

After World War II, in an attempt to overcome the difference in gauges and speed up traffic, a bogie exchange device lifted freight wagons and carriages allowing workers to refit rolling stock with different gauged wheel-sets.

Bogie exchange was used between and gauge on the Ferrocarril de Antofagasta a Bolivia Railway.
In the meantime, the railway became proficient in changing bogies on freight cars between gauges at interchange points.

Terra Transport

Significant time was lost at Port aux Basques, where standard-gauge railway cars from mainland North America were lifted off their bogies and onto narrow-gauge bogies for use on Newfoundland.

Train ferry

A bogie exchange station in the port of Mukran serves train ferries that go to and from Russia, Latvia, and Lithuania, which have broad gauge.
Bogie exchanges take place in Mukran.

Brest, Belarus

* Brest, Belarus – between gauge and at the border to Poland
Because of the break-of-gauge at Brest, where the Russian broad gauge meets the European standard gauge, all passenger trains, coming from Poland, must have their bogies replaced here, to travel on across Belarus, and the freight must be transloaded from cars of one gauge to cars of another.

Newfoundland Railway

New railcar-capable ferries were introduced; mainland standard-gauge railcars were ferried to Newfoundland, where their standard-gauge bogies were replaced with narrow-gauge bogies in Port aux Basques.

The railway has no fixed connection with the mainland, and rail cars coming from the mainland port of Vanino on the Vanino-Kholmsk train ferry (operating since 1973) have their bogies changed in the Sakhalin port of Kholmsk.

By the mid-1960s, new railcar-capable ferries such as the MV Frederick Carter permitted the exchange of standard gauge railcars, requiring further expansion at the Port aux Basques terminal facilities.

The break-of-gauge point is several hundred meters inside Finland at Turku and the bogies are exchanged in a specially-equipped depot; this procedure can be achieved in 10 minutes and involves jacking up each wagon.

Track gauge conversion

Bogie exchange is a system for operating railway wagons on two or more gauges to overcome difference in the track gauge.
Where vehicles move to a different gauge, they must either be prepared for bogie exchange or be prepared for wheelset exchange.

In railroad industry, the Ramsey car-transfer apparatus (Ramsey transfer) was a device to replace bogies on railroad cars to permit transfer of a train between railroad lines with different gauge.

Variable gauge

Variable-gauge axles in an automatic track gauge changeover system (ATGCS) is a newer development and is faster than bogie exchange.
Although several alternatives exist, including transferring freight, replacing individual wheels and axles, truck exchange, transporter flatcars or the simple transshipment of freight or passengers, they are impractical, thus a cheap and fast system for changing gauge would be beneficial for cross-border freight traffic.

A bogie exchange station exists in the Port of Turku with a short stretch of gauge railway.
The tracks in Stockholm and on the ferry itself were standard gauge, with a short section of standard gauge in the harbour area to enable hauling the wagons off the ferry before the gauge of the axles was altered using bogie exchange.

SUW 2000

The SUW 2000 ATGCS requires a changeover track about 20 m long, with a shed if snow is around compared to a small marshalling yard required by bogie exchange.
It is used at two border stations, enabling trains to Lithuania and Ukraine to proceed without the need for lengthy bogie exchange.
