Level crossing protection systems: barriers and other devices

Our company offers solutions in full compliance with global railway regulations and based on the specifications issued by the RFI (Italian Railway Network), an organisation recognised internationally for its high safety standards.

These are necessary to ensure the safety of motorists crossing the railway crossing and of train passengers. When a train approaches, the level crossing systems receive the close command from the detection sensors and, at the same time, the road lights and bells are activated, indicating that the barriers are about to close. When all these operations are completed properly, the train proceed signal light comes on.
The passage of the train over the crossing is monitored by an axle counter system that guarantees the command to reopen the barriers in less than two seconds, only after the entire train has passed. These are critical steps that require reliable and safe solutions.

Focus on safety and quality

Thanks to our know-how, WEGH Group is able to offer modular and configurable products, ranging from individual components to complete systems for level crossing protection. We offer complete systems for level crossing protection for railways and tramways.

The eLCSP (electronic Level Crossing Safety & Protection) system

To ensure total safety of crossings, WEGH Group has introduced the eLCSP (electronic Level Crossing Safety & Protection) system. This is an electronic command and control system which, through electronic components (PLC, Programmable Logic Controller) in 2oo2 configuration, is able to safely guarantee the automation of the closing and reopening sequence of level crossings, controlling the barriers, the audible and light signals on the road side, and the light signals on the train side. Its operating logic can be configured to manage different scenarios, without making complex hardware changes: a feature that ensures a high level of flexibility.

eLCSP is supplied already configured for the application chosen by the client, the relative software modules are installed upstream, taking into account the specifics of the crossing. Furthermore, the eLCSP system does not require any special maintenance, because there is a diagnostic system that operates through ad hoc sensors that can predict the state of deterioration.

eLCSP has railway SIL (Safety Integrity Level) 4 certification, i.e. the highest level of safety integrity, defined as the level of risk reduction guaranteed by a safety function, or specified as a target level of risk reduction. An example of the characteristic quality of all our group’s electronic level crossing systems.

eLCSP

eLCSP (acronym for Electronic Level Crossing Safety & Protection) is a comprehensive safety and protection system for the level crossing area. The control logic is managed by electronic components (PLC). This system implements standard UNI 11117 and provides for a safety level equal to SIL4, as required by standards IEC EN 50126, 50128 and 50129. It is extremely modular and configurable and it has many options available.

LCSP

LCSP (acronym for Level Crossing Safety & Protection) is a comprehensive safety and protection system for the level crossing area. The control logic is managed by electromechanical components (relays). This system implements standard UNI 11117 and the EU standards IEC EN concerning railway applications. It is modular and easy to adapt to different installation contexts.

BARRIER MACHINE FOR LEVEL CROSSINGS TD96/2

The barrier machine TD96/2, which was approved by RFI (Italian Railway Network) in 2006, is the ideal solution for Italian railways with over 9,000 operating units installed along the line, achieving a reliability index equal to 98%. Distinguishing features of this machine also include safety, robustness and easy maintenance.

HYDRO-ELECTRIC TRAIN DETECTOR P70

The hydro-electric train detector P70 is designed to detect transiting trains and it is the ideal solution to control safe level crossing clearance. It is made of a detector installed under the rail and an amplifier placed on the side of the track, both of which are conceived to prevent any form of accidental activation. The time for the release of the electrical contacts can be set up.

LED LIGHT SIGNALS

WEGH Group designs and manufactures LED light signals for level crossings to be installed on both the road and the railway side, in different configurations.
