Within the ENYSE business areas, one of the activities is the implementation of Level Crossing Protection systems, with over 800 level crossings installed at various railway administrations.
Level crossing protection systems, with a tried and tested, robust and easy to maintain design, are fail-safe and SIL-4 according to CENELEC standards, allowing a range of wired and radio-controlled configurations and solutions to be installed.
- ENYSE manufactures, supplies and installs Level Crossing Protection systems type:
- SLA – Level Crossing Protection systems by light – acoustic signalling (in stretches of railroad tracks fully automated)
- SBA – Level Crossing Protection systems with Automatic Half-Barriers (near stations or in stretches of railroad tracks fully automated
- SBE – Level Crossing Protection systems with Interlocked Half-Barriers (commanded from the station)
All Level Crossings Protection Systems can be associated with the Pedestrian Protection System. Also related to this, object detection systems at Level Crossings are designed to grant the Safety of the railway and road traffics. However, they may be supported by other systems, reporting obstacles or undue detections at the intersections between rail and road.
In this environment, Enyse has developed the new ENYVODD Object Detection System using Artificial Vision Cameras. These systems will allow the gradual replacement of the current object detectors using loops by a new generation, more reliable state-of-the-art technology, which will also require less maintenance.
This new camera system is based in the use of video analysis technologies. At the Level Crossing area, a series of video cameras will be installed covering the intersection of the railway track with the vehicles’ road zone. The system continuously processes the images taken by the cameras and is capable of detecting the presence or absence of obstacles at the crossing and thus communicate its state to the railway Signalling logic.
For the contract execution, Enyse relies on the technical support in the field of artificial vision of ITERA TÉCNICA SL, a technological company with a wide experience offering specialized engineering services.
ENYSE supplies and installs this kind of railway wayside signals:
- Conventional spotlights signs: high and low.
- LEDs signals for specific indications, monoled and multiled.
- Fiber Optic Signs with dual lamps.
- Reflective mechanical signals.
ENYSE fits signals to the signaling systems of each country and provides all the necessary elements for installation and operation.
The Point Machines used by ENYSE in its facilities are of proven design, robust and easy to maintain. They may be installed on both sides of the track.
ENYSE supplies these kind of Point Machines:
- Electrical: Both single and three phase.
- Mechanical: The drives used by ENYSE suit the specifications of the Railway Administrations of each country.
Locking systems that may be installed include:
- Carter-Coussinet
- Claw-Lock mechanism
To check the point’s position at mechanical drives, ENYSE provides position detectors of the PAULVÉ type .
ENYSE supplies and installs detection systems based on:
- Jointless Track Circuits of the Audio frequency type
- ITE Track Circuits of high voltage pulses
- Conventional track circuits of 50 Hz – with electrical isolation joints
- Axle Counters. ENYSE has used and installed wheel detector type RSR122 / 180 with electronic axle counter type Frauscher ACS2000.
The ACS2000 axle counter is approved in ADIF by ENYSE since 2003. It’s currently installed in various lines of ADIF, former FEVE, as well as in Chile – with over 200 track circuits installed.
The ACS2000 is an axle counter for rail traffic, developed and specially designed for use in all types of railway lines, including high-speed lines and last generation trains.
The basic principles that have guided the design of the equipment ACS2000 are:
- Standardization. The ACS2000 is a device developed to meet the stringent regulations in Germany and in accordance with the Mü8004 standard, which was used as a basis for drafting the current CENELEC standards EN 50129.
- Compliant Standards EN50129, EN50128, EN50129, SIL / SSAS 4 and EN50159-2 Clase5
- Robustness and reliability in operating environments of this equipment both electrically and with different types of equipment on board on trains.
- Safe operation in accordance with the regulations of the German Mü8004 DB.
- Ease of Maintenance, based inter alia on modularity and non-use of active electronics on track, and ease of use with all kinds of old facilities as electronic interlocking.
- Ease of operation, both locally and remotely through independent inputs for each channel and potential free outputs.
- Ease of Integration with Signaling Systems and train detection systems, as security for transmission between stations for various applications such as automatic locking between stations, control and verification of distant elements or hub of information in stations recorders.
Regardless of the technology used to detect trains, are perfectly integrated with electronic or electrical interlocks and level crossings protection systems types: SLA, SBA or SBE.
ENYSE designs communication protocols for their systems under the strictest safety standards, using the latest media transmission technology based on FO, radio and cable.
This experience allows integrating technology solutions from different vendors, adapting our designs to customer requirements, such as:
- GSM-R system
- Operational Telephone Systems
- Digital Transmission Systems: Both PDH and SDH technology
- Communication Systems – Track to Train, as per the current technical specification in Spain
ENYSE integrates, supplies and installs these kind of Auxiliary Systems:
- Public Address Systems
- Passenger Information Systems
- Timing systems
- Control and video surveillance systems
During the installation phase ENYSE adapts auxiliary systems to the use of railway staff and passengers in each country.
