Gauntlet track

Frog gauntlets are also commonly used when a rail line's capacity is increased by the provision of an additional track, but cost or other factors prevent the widening of the bridges.

Gauntlet tracks are also often used at weigh scales so that locomotives can bypass the equipment to avoid accidental damage.

At a small number of locations on single track lines in Britain, interlaced loops had been provided where sprung catch points were required because of the steep gradient.

In Melbourne, broad (1600 mm) and standard dual gauge gauntlet track is located within the passenger yard of Southern Cross station, and in platforms 1 and 2.

The northern section of the Upfield line, between the Ford sidings and Somerton, is also dual gauge gauntlet track.

In Brisbane, standard and narrow (1067 mm) dual gauge gauntlet track is located on platform 2 of Roma Street station.

The Toronto Streetcar System includes a very short section of gauntlet track on Queen Street East, at Coxwell Avenue.

[11] A loop allowing southbound cars to return northbound on Coxwell Avenue briefly interlaces with the westbound track on Queen Street, due to turning radius limitations.

Other similar stretches were removed or re-organised, since according to the standards, gauntlet tracks on tram lines are only permitted as a temporary measure.

[14] Similar arrangements exist on the approach to Kaliningrad, where 1435 mm (4 ft 8+1⁄2 in) track extends from the Polish border with some sections of dual gauge.

This happens at the southern terminus of the Seattle Center Monorail at the Westlake Center in Downtown Seattle, Washington, where the station was rebuilt in 1988 with the dual tracks only about 4 feet (1.2 m) apart in order to allow for a narrower station, which led to a collision in 2005 that suspended monorail service for several months.
