Transformer crossing
In transformer stations, the transformation of electrical energy between two or more voltage levels takes place. This requires transformers that can weigh up to 500 tons. In order to move these transformers, some transformer stations have their own rail connection. Where the various tracks of a transformer station cross, our transformer track crossings are used. […]

Lay-on switch
Lay-on points, also known as climbing points, are auxiliary constructions that are mostly used at track construction sites. These points are placed on the existing track to temporarily redirect rail vehicles to another track. The ramp-shaped ends of the laying points allow the rail vehicles to drive onto the points and be diverted. We always […]

Rail scales
Static railway scales are used to weigh rail vehicles and are often found near loading tracks. In the case of railway weighbridges with a track interruption, the running rails in the area of the railway scales are on the wagon bridge and are separated from the rails of the connecting tracks. The critical points in […]

Side devices
Setting devices can be used in addition to switch locking systems (point and center locking). The setting device is used to hold the movable tongue rail of a point in the area of the narrowest passage groove at a defined distance from the stock rail (outboard tongue). On the opposite side, the tongue rail is […]

Switch locks
With their movable tongue rails, points enable uninterrupted switching between individual tracks. Our point locking systems ensure that points are set securely and that the tongue rail is in full contact when trains are running over them.

Rail support points
For long-lasting, low-maintenance and vibration-reduced use on bridges and solid road surfaces.

Fishplates
Fishplates are attached to the rail ends to transfer forces from one rail end to the other. Fishplates can be used to connect both the same and different rail heights. Fishplates are usually made of flat steel; however, it is also possible to make them from fishplate profiles.
Read moreTrack spacer
Rail spacers are used to ensure the correct distance between the rail and the edge of the platform. The various models are suitable for use with wooden, concrete and steel sleepers. The extension length can also be customized to meet individual requirements.

Cable crossing sleepers
The cable crossing sleeper offers a possibility to insert power, signal and communication cables and to protect them against the effects of the weather. Due to the fact that the weight and size of a standard DB sleeper are modeled, the cable crossing sleeper can be easily installed in the ballast bed. Accordingly, the installation […]

Drainage boxes
The use of track drainage boxes ensures that precipitation drains away quickly. This means that rainwater and dirt cannot affect rail traffic. With the help of the removable cover, impurities and dirt can be easily removed. Various: gauges, rail profiles, pipe connections, cover openings, load classes

Steel sleepers
The steel sleeper is one of the most durable and low-maintenance components in the superstructure and, due to the material properties, it is also the most versatile sleeper. The sleeper can be manufactured as a profile St82, Sbb1 and UIC28 or DS9 and is used as a main-track or turnout sleeper. Due to the low […]

Rail extensions
The rail expansion joints are used to compensate for the expansion in the movements (longitudinal forces) of the rail on bridges (e.g. braking and acceleration) and strong temperature influences. The expansion device is installed in front of and behind the structure and usually consists of two stock and tongue rails that can move against each […]
Read more
Safety and guiding device
Guide rails are used in particularly critical areas as derailment protection to prevent major damage to adjacent structures (such as bridges). For this purpose, another standard rail is attached to the sleeper next to the running rail as a guide rail. This creates a guide groove which ensures that the train is kept on track […]
Read moreBase plates for slab track
The steel base plate is used for rail fastening on slab track for optimal load distribution. The forces that occur are transmitted through the base plate to the elastic intermediate plate in this system.

Support trestle plates
Check rail plates are used to secure check rails in the frog area to ensure that the railroad wheels are guided particularly safely. We usually manufacture check rail supports in a welded design. However, for particularly large batch sizes, a cast or forged design is also conceivable.
Read more
Centerpieces
Centerpieces are among the most important components of points and crossings. They serve as a point of intersection where the running edges converge at an acute to right angle. In short, when the rails have to be interrupted to intersect, the crossing ensures that the wheel flange of a railroad wheel can pass through unhindered […]

Tongue roller devices
Tongue roller devices enable the tongue rail to be switched without lubrication and with little friction. The use of rollers eliminates sliding friction between the foot of the tongue rail and the surface of the slide chair or slide plate, replacing it with rolling friction. We offer our customers a range of slide chair plates […]
Read more
Sliding chair plates
Slide chair plates are used in the tongue devices of points with asymmetrical tongue profiles. Since there is a height difference between the stock rail and the lower tongue rail, the slide chair serves as a raised support and sliding surface on which the tongue rail can move and rest. We usually design the inner […]

Closure thresholds
Closure sleepers replace a standard sleeper in the tongue mechanism of a point and serve to integrate the point lock as well as the check and setting rods. These are thus protected against the effects of the weather and damage. Since the use of a closure sleeper eliminates the need to position the lock and […]

Check rail
In the area of frogs, railroad wheels must be guided separately and securely so that they can bridge the interrupted rail. We manufacture wheel guides in standard and special designs for vignol and grooved rail turnouts.

Ribbed plates
Ribbed plates serve as a connecting element between the threshold and the rail. The ribs on the plate serve as a lateral guide for the rail and as a fixing point. For this purpose, the head of the hook bolt is inserted into the dovetail-shaped recess between the ribs so that the shaft can be […]
