Dual gauge

A dual gauge railroad track has three or four rails, allowing vehicles of two track gauges to run on it.

Triple-gauge for metre (1000 mm), standard (1435 mm), and Russian (1524 mm) gauges at Škoda's facility in Plzeň, Czechia. Numbering rails 1 to 5 from left to right at the top of the image and A to D at the bottom, the metre-gauge track uses rails 2/3 and B/C, the standard-gauge track uses rails 1/4 and B/D, and the Russian-gauge track uses rails 2/5 and A/C. This changeover allows to change which common rails are used by which gauges, transitioning from 4 rails to 5 rails. The metre-gauge track is configured for tram wheelsets, as can be seen by the smaller gap between rail 3 and its check rail.

The Gorton Foundry of Beyer, Peacock & Company was typical of locomotive and rolling stock manufacturers that exported to many countries. This track of four gauges traversed two turntables, requiring the rails to be centralised.

Standardised containers have revolutionised rail, road and sea freight transport. Although mechanisation has sped up handling, moving containers from one train to another because of different rail gauges is costly and inefficient.
Gauntlet track

Gauntlet track, also called interlaced track or gantlet track is an arrangement in which railway tracks run parallel on a single track bed and are interlaced in such a way that only one pair of rails

…tunnels or other constricted locations. Such configurations, when they revert back to standard parallel lines as soon as room is available, are termed "gauntlet track" (US: "gantlet track"). Four rails must be placed identically on either side of the central axis of dual-gauge turntables (and six rails on triple-gauge turntables) so that…

Triple gauntlet track at Kaufungen, Germany. Wider mainline trains go down the centre; narrower trams switch either to the left, or right, to be closer to the appropriate platform. Beyond the station, the rails return to single track.
