Siemens is the leading supplier of complete rail automation products and solutions for all kinds of railway systems be it Mainline or Metro.
Various products offered in this category include
1. Automation for Mainline and for Metro Projects
Siemens modern signaling systems are designed for safety, speed and economy. A high standard of technical reliability and operational safety are ensured by incorporating proven design and latest components technology. Siemens Signaling and Control Equipment offer many advantages such as a Remote Control System in which all the operations, dispositions and statistical data are centrally processed and automated. It can handle the traffic with speed and safety. It is available for any range and size of operational requirements.
This can be operated by a operator by pressing two buttons or by computerized programming schedule which will enable setting of safe train routes and automatically eliminate all conflicting moves. At the same time, the operating conditions are continuously indicated on the control panel.
Siemens K50 Relay is failsafe, non fault prone and a positive function. It is a vital component used in Railway Signaling circuits. Its series contact layout serves optimally in case of contact rupturing or breaking reliability. In addition to this, contact performs a wiping and a self cleaning action, providing sufficiently long friction action and consequently positive contact making.
3. Audio Frequency Track Vacancy Detection
Audio Frequency Track Circuit is designed as a track vacancy detection system for main line as well as metro, urban, and suburban railways. The isolation between two tracks is achieved by means of electrical separation joints.
Siemens FTGS is a state-of-the-art track circuit equipped with extensive operating state indicators that allow additional information to be transmitted via rails to the train by means of external control circuit. Its remote fed and led indications gives number of advantages, i.e. high reliability, high availability and easy maintenance.
4. Axle Counter
Track vacancy detection systems provide reliable information on the clear and occupied states of track sections, thereby making the railway operations smooth.
The AZ S 350 U system of Axle Counters offers high economic efficiency by low initial cost, high reliability and high availability by fault- tolerant evaluation of the pulse count through multiple axle counting method, space saving compact design, easy reconfiguring using DIP switches, and interfacing with all interlocking types via parallel relay interface.
BPAC provides all safety requirements of absolute block working between two stations: Track vacancy detection and failsafe block information transmission by Axle Counter system of SIEMENS Az S 350 U, safe communication protocol by using the hamming distance of 9 and all safety circuits wired using K50 Relays having extra features such as rigid contact carriers with double break contact arrangements.
6. Auxiliary Warning System
The Auxiliary Warning System is the economic solution for safer and more flexible operations; A solution for running more trains in any time interval. The information is transmitted from the line to the train by this equipment. It continuously monitors the maximum authorized speed and the braking procedures. Driver gets operating information for the section ahead and also receives optical and acoustical warnings in advance.
The system introduces service braking to control the speed with reference to the signal aspect and helps applying emergency braking in a dangerous situation.
7. Point Machines
Point Machine is an electrically motor operated device, which throws a point of railway track in one direction or the other. The Siemens S 700 K Point Machine is used to throw points of all types and gauges. It can be used for all points with external locking. Even derailers and locks, e.g. on lift and swing bridges or lock gates can be operated with this point machine.
8. Thermo Flasher
Mercury Flasher is used for generating a flashing source from a steady input for flashing indications on the relay interlocking control panel or cabin.
