Bogie exchange

In 1944, the LMS re-gauged a pair of "Jinty" 0-6-0 tank locomotives – originally built to UK 4 ft 8+1⁄2 in (1,435 mm) standard gauge – for use on its 5 ft 3 in (1,600 mm) gauge Northern Counties Committee (NCC) lines in Northern Ireland; re-designated as Class Y, they largely undertook shunting work on dockyard lines in Belfast.

Diesel locomotives have bogies like wagons and carriages, only with more cables for the traction motors and take a little longer to convert.

[3] Charles Tisdale patented a system of ramps and moving supports for lowering the trucks out from under a railroad car in 1873.

[4] George Atkinson patented a hoist and transfer table arrangement in 1882; this dropped the bogies from under a car and shift them to the side.

[5] Ramsay's apparatus patented in 1884 used hydraulic jacks to support the car while lowering the track with the bogies out from under it.

[6] Between 1961 and 1995, Australia had five bogie exchange centres, which opened and closed as gauge conversion work proceeded.

The centres were: The busiest facility was that at Dynon, in a typical year (1981–82), 24,110 wagons were bogie exchanged, an average of 66 per day.

[12] A bogie exchange station exists in the Port of Turku with a short stretch of 1,435 mm (4 ft 8+1⁄2 in) gauge railway.

In 1898, Emil Breidsprecher, a director of the Marienburg–Mława railway and a future professor at the Königliche Technische Hochschule zu Danzig,[13] invented a system that allowed to change wheelsets in wagons that travelled across a break of gauge, without the need to unload them first.

[15] Known locations, in addition to Iłowo, are Łódź (then an industrial centre served by both standard and broad gauge railway lines) and Novoselytsia (then Austrian-Russian border).

[16] A bogie exchange station in the port of Mukran serves train ferries that go to and from Russia, Latvia, and Lithuania, which have 1,520 mm (4 ft 11+27⁄32 in) broad gauge.
