The first use of the Scharfenberg coupler was for the Manila MRT Line 3 in 1999. Meanwhile, the first use of the Shibata coupler was for the LRT Line 2. In the future, Shibata couplers are also expected for use on the MRT Line 7, the Metro Manila Subway, and the North–South Commuter Railway (NSCR). The NSCR is so far the only PNR line that ...
The Schwab coupler is an automatic coupler manufactured by Schwab Verkehrstechnik AG, Schaffhausen, the legal successor to the Railway Coupler Division of Georg Fischer. The coupler automatically makes the mechanical, pneumatic and electrical connections. The mechanical locks are located on either side of the pneumatic ports.
A 10 dB 1.7–2.2 GHz directional coupler. From left to right: input, coupled, isolated (terminated with a load), and transmitted port. A 3 dB 2.0–4.2 GHz power divider/combiner. Power dividers (also power splitters and, when used in reverse, power combiners) and directional couplers are passive devices used
The diagram from Beard's 1897 coupler patent [1]. Janney couplers were first patented in 1873 by Eli H. Janney (U.S. patent 138,405). [2] [3] Andrew Jackson Beard was amongst various inventors that made a multitude of improvements to the knuckle coupler; [1] Beard's patents were U.S. patent 594,059 granted 23 November 1897, which then sold for approximately $50,000, and U.S. patent 624,901 ...
Norwegian coupler, also known as chopper or Jones coupler; pin and cup coupler (WABCO N-Type) SA-3, also known as SovietAuto-3, AK69e, CA-3, Russian or Willison coupler; Scharfenberg coupler, also known as Dellner, Schaku or Voith coupler While different Scharfenburg couplers may be mechanically compatible, they may be electrically incompatible.
Type H Tightlock couplers on a California Car cab car with separate air brake and head end power connections. Type H Tightlock couplers are a variety of Janney coupler, typically used on North American mainline passenger rail cars. They have mechanical features that reduce slack in normal operation and prevent telescoping in derailments, yet ...
Digital automatic coupling (DAC) is a type of railway coupling developed in the 2020's to replace the English buffers and chain couplings, initially in Europe.. It resembles the Scharfenberg coupler with extra contacts to join electrical circuits (power, detection and control) and air hoses.
The dual couplers are mounted to a pivot, allowing both to swing. Different types of railroad rolling stock have different couplers depending on the purpose and type of equipment being used and its intended destination. European rolling stock tend to use buffers and chain couplers while American rolling stock uses a Janney coupler or "knuckle ...
