A rail system mounted on top of a SIG SG 550 A dovetail rail on a rifle receiver for mounting a sight. A rail integration system (RIS; also called a rail accessory system (RAS), rail interface system, rail system, mount, base, gun rail, or simply a rail [1]) is a generic term for any standardized attachment system for mounting firearm accessories via bar-like straight brackets (i.e. "rails ...
A cowcatcher, also known as a pilot, is the device mounted at the front of a locomotive to deflect obstacles on the track that might otherwise damage or derail it or the train. In the UK, small metal bars called life-guards, rail guards or guard irons are provided immediately in front of the wheels. They knock away smaller obstacles lying ...
It is an Open architecture system, as there was an explicit requirement for it to be interoperable between multiple vendors unlike in the case of Anti-Collision Device (ACD). [9] During 2014, the deployment of an initial trial system along a 265 km section of line commenced, upon with the first real world evaluations of Kavach were performed. [9]
Train-mounted trip cock, located on the leading bogie of a Siemens EMU. The train stop system comprises two basic components. One is the trip arm mechanism, mounted on the ground adjacent to the rail, which essentially consists of a spring-loaded arm connected to an electric motor (or pneumatic cylinder in electro-pneumatic systems).
The technology works by having the state of a track mounted shoe read by a receiver mounted to a truck on the leading locomotive or car. In the standard implementation the shoe is mounted to the ties a few inches outside the right hand running rail, although in theory the shoe could be mounted anywhere on the ties. [1]
The only significant difference between the MIL-STD-1913 rail and the similar Weaver rail mount are the size and shapes of the slots. Whereas the earlier Weaver rail is modified from a low, wide dovetail rail and has rounded slots, the 1913 rail has a more pronounced angular section and square-bottomed slots. This means that an accessory ...
In the United States, the General Railway Signal corporation introduced its Intermittent Inductive Automatic Train Stop system in the 1920s which made use of inductive loops in a "shoe" mounted outside of the running rails. This system was also of the acknowledgment type and was adopted by several railroads, continuing to see service as of 2013.
This is inadequate for detection of rail tracks separated by a distance of 10–15 feet (3.0–4.6 m). ACD does not even have DGPS, differential GPS that gives an accuracy close to 2.5 m, and hence had errors in track detection using their patented Deviation Count Theory that worked in block sections but failed in station sections.
