Rail signals
A modular concept for various customer applications
Flexible and modular
In order to meet various customer requirements, the different components can be built from a wide range of modular designs, allowing you to configure your own system as desired.
High availability and reliability
We offer proven, innovative, eco-friendly solutions for maximum availability, efficient operation, and cost-effectiveness fundamental to the smooth and safe running of railway operations.
Economical and virtually maintenance-free
Thanks to the use of LEDs and corrosion protection, maintenance is limited to the replacement of signal lamps and cleaning of optical components – thus further reducing operating costs.
A comprehensive range
The solution where space is limited
The Sigmaguard K140 compact signal can be operated wherever standard light signals with large dimensions cannot be installed due to space restrictions. This signal type is suitable for tunnel applications as well as for open areas with a reduced range of visibility.
Benefits
- Compact design for applications with limited space
- High versatility for different applications due to modular concept
- Easy access to the housing interior for maintenance
Efficient application of modular color light signals
The Sigmaguard S640 is a compact signal for mainline customers with varying degrees of signaling complexity. The high-grade steel housing with a width of 640 mm accommodates up to nine LED units of different diameters. The clear customer benefits also apply to compact signals of other dimensions.
Benefits
- Flexible and modular: both housing and LED units can be chosen from an extensive modular system
- Proven mounting elements for all common types of signal post and supporting structures
- High availability and optimized operating costs with proven LED components
Shunting solution for Deutsche Bahn
The Sigmaguard Ls-Signal is a proven product for shunting in Deutsche Bahn's portfolio. One of the key features is optimized close-range and phantom-light behavior. This results in enhanced signal recognition, and therefore, greater reliability and safety for the operator.
Features
- Flexible use due to variable arrangements
- Optimized electronic interface
- Robust and compact stainless-steel casing
- Extendable for use with ATO systems
Benefits
- Greater visibility due to greater brightness
- Improved close-range visibility
- Minimal light phantoms
- Reduced operating costs, as almost maintenance-free
- High reliability and availability thanks to long lifecycle
LED multiple indicator completes our global portfolio
The Sigmaguard MA480 indicator is used for additional signaling information, e.g. speed limits, route indications etc. It can display a maximum of four different symbols, each consisting of up to 20 pixels in white or green. Based on the stipulated clearance gage requirements and thanks to its design: the LED indicator features a maximum indication surface, optimizing the legibility distance.
Benefits
- Optimized legibility and visibility
- Display of up to four different symbols
- Reduced maintenance work and operating costs
High-performance LED units
Cost-effective operations management
Our LED units are the key optical component of all our signaling products. Compared to filament lamps, they provide significant advantages from both a technical and commercial point of view.
Benefits
- High availability and reliability
- Optimized operating and lifecycle costs
- Low maintenance requirements
Sigmaguard LED70
The Sigmaguard LED70 is designed for applications in tunnels as well as for open areas with a reduced range of visibility. The LED unit has a nominal diameter of 70 mm and is available in yellow, red, green, white and blue. It is preferentially used with the K140 compact signal.
Sigmaguard LED136
The Sigmaguard LED136 unit is made for larger luminous ranges, mostly in mainline or freight applications. The LED has a nominal diameter of 136 mm and is available in yellow, red, green, white, and blue. Besides its use in compact signals, such as the S630, it can also be operated in a single light unit with its own robust housing.
Sigmaguard LED210
The Sigmaguard LED210 unit is used for similar applications as the Sigmaguard LED136 and is available in the same colors. With its nominal diameter of 210 mm, it comes with its own housing conforming to a high protection class.
Sigmaguard SIO Basic – Savings all around
The LED units of the Sigmaguard SIO Basic are setting new standards in terms of economy, downward compatibility, and low maintenance. They are the first to feature the multiple use of several, separately controllable signaling signs in one diode. The resulting lower number of diodes leads to smaller signal backgrounds. An additional key feature is the implementation of optical sensors that constantly monitor the signal's light intensity, ensuring the required performance.
Benefits
- Intelligent monitoring of light intensity
- Optimized reliability and availability
- Reduced number of light points required due to multi-color LEDs
- No pre-determined lifetime limitation
Sigmaguard Pharos 8'' LED wayside aspect modules are fully AREMA compliant
The vital wayside 8'' LED Sigmaguard Pharos™ is created to meet the requirements of our mainline and freight customers on AREMA markets. The LED has the diameter of 200 mm (8 inches) and is available in medium (1/2 mile) and long-range (1 mile).The colors are red, yellow, green, and lunar white.
Benefits
- Vital light out detection via optical monitoring
- More than 50% reduction in retro-reflectivity (phantom aspects) with a patented four lens system
- The only LED that is fully compliant with AREMA chromaticity requirements
