2. Railway air brake - Wikipedia

   en.wikipedia.org/wiki/Railway_air_brake

   A railway air brake is a railway brake power braking system with compressed air as the operating medium. [1] Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. [2] The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's ...

3. Dual gauge - Wikipedia

   en.wikipedia.org/wiki/Dual_gauge

   The signalling system detects the gauge of the approaching train and puts the signals to stop if the route is set for the wrong gauge. In Queensland , there is a section of 1067 mm ( 3 ft 6 in ) and 1435 mm ( 4 ft 8 + 1 ⁄ 2 in ) dual-gauge track between the rail freight yards at Acacia Ridge and Park Road station , which is utilised by both ...

   A mechanical scale or balance is used to describe a weighing device that is used to measure the mass, force exertion, tension, and resistance of an object without the need of a power supply. Types of mechanical scales include decimal balances, spring scales, hanging scales, triple beam balances, and force gauges.

5. Railway coupling - Wikipedia

   en.wikipedia.org/wiki/Railway_coupling

   A coupling or coupler is a mechanism, typically located at each end of a rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train.

   A well car, also known as a double-stack car (or also intermodal car / container car), is a type of railroad car specially designed to carry intermodal containers (shipping containers) used in intermodal freight transport. The "well" is a depressed section that sits close to the rails between the wheel trucks of the car, allowing a container to ...

7. Rail gauge in Australia - Wikipedia

   en.wikipedia.org/wiki/Rail_gauge_in_Australia

   The three main railway gauges in Australia are narrow: 1,067 mm (3 ft 6 in), standard: 1,435 mm (4 ft 81⁄2 in), and broad: 1,600 mm (5 ft 3 in). A slow progression towards unification to standard gauge has taken place since the 1930s. [3] About 4,000 km (2,500 mi) of 610 mm (2 ft) light railways in Queensland support the sugar-cane industry.
