Railway engineering is a multi-faceted engineering discipline dealing with the design, construction and operation of all types of rail transport systems. It encompasses a wide range of engineering disciplines, including civil engineering, computer engineering, electrical engineering, mechanical engineering, industrial engineering and production engineering.
The American Railway Engineering and Maintenance-of-Way Association (AREMA) is a North American railway industry group. It publishes recommended practices for the design, construction and maintenance of railway infrastructure, which are used in the United States and Canada .
Railroad terminology defines the following types of interlockings as either complete or incomplete depending on the movements available. Although timetables generally do not identify an interlocking as one or the other, and rule books do not define the terms, the terms below are generally agreed upon by system crews and rules officials.
The minimum railway curve radius is the shortest allowable design radius for the centerline of railway tracks under a particular set of conditions. It has an important bearing on construction costs and operating costs and, in combination with superelevation (difference in elevation of the two rails) in the case of train tracks , determines the ...
In railway engineering, curve resistance is a part of train resistance, namely the additional rolling resistance a train must overcome when travelling on a curved section of track. [1] Curve resistance is typically measured in per mille , with the correct physical unit being Newton per kilo-Newton (N/kN).
In civil engineering, cant is often referred to as cross slope or camber. It helps rainwater drain from the road surface. Along straight or gently curved sections, the middle of the road is normally higher than the edges. This is called "normal crown" and helps shed rainwater off the sides of the road. During road works that involve lengths of ...
Unimog pushing a "Spindle Precision Wrenching Unit" used for automatic and synchronous tightening and loosening of rail fastenings Mabbett Railway Chair Manufacturing Company share certificate (1867) A rail fastening system is a means of fixing rails to railroad ties (North America) or sleepers (British Isles, Australasia, and Africa).
The headstocks form part of the underframe of a locomotive or a railroad car. The headstocks of locomotives , railcars and cabcars also support headlamps and the hoses for air brakes , vacuum brakes as well as the cables for train control and head end power .
