The US and Canada departed from UK practice wherein a semaphore blade is devoted to each route (Route Signaling). General North American practice is to group routes by speeds and use a single blade for, say, "medium speed" regardless of the number of routes involved (Speed Signaling). The primary exception to this situation is in the field of ...
A unit (US) A BNSF Railway A unit A diesel locomotive (or more rarely an electric locomotive) equipped with a driving cab and a control system to control other locomotives in a multiple unit, and therefore able to be the lead unit in a consist of several locomotives controlled from a single position [9]
INTERBUS is a serial bus system which transmits data between control systems (e.g., PCs, PLCs, VMEbus computers, robot controllers etc.) and spatially distributed I/O modules that are connected to sensors and actuators (e.g., temperature sensors, position switches). The INTERBUS system was developed by Phoenix Contact and has been available ...
Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems.
Once a route is set and a train is given a signal to proceed over that route, all switches and other movable appliances in the route are locked in position until either the train passes out of the portion of the route affected, or; the signal to proceed is withdrawn and sufficient time has passed to ensure that a train approaching that route ...
The AS-Interface has been an international standard according to IEC 62026-2 since 1999. AS-Interface is a networking alternative to the hard wiring of field devices. It can be used as a partner network for higher level fieldbus networks such as Profibus , DeviceNet , Interbus and Industrial Ethernet , for whom it offers a low-cost remote I/O ...
The Western Railway (abbreviated WR) is one of the 19 zones of Indian Railways and is among the busiest railway networks in India, headquartered at Mumbai, Maharashtra. The major railway routes of Indian Railways which come under Western Railways are: Mumbai Central – Ratlam , Mumbai Central– Ahmedabad and Palanpur –Ahmedabad.
Multibus is a computer bus standard used in industrial systems. It was developed by Intel Corporation and was adopted as the IEEE 796 bus. [1] The Multibus specification was a robust industry standard with a relatively large form factor, allowing complex devices to be designed on it.
