Prefabricated narrow-gauge crossing
A prefabricated structure designed for rapid installation in locations critical to transport operations, while taking into account the specific characteristics of narrow-gauge infrastructure.
About the product
Prefabricated narrow-gauge crossings
The CONTRACK prefabricated narrow-gauge crossing is a crossing surface system designed for installation at intersections of narrow-gauge railway lines with public roads, internal roads, and pedestrian routes.
The solution has been developed with the specific characteristics of narrow-gauge infrastructure in mind, including varying track gauges, geometric constraints, and the operational requirements of tourist, heritage, and industrial railway lines.
Construction
Dedicated construction
CONTRACK prefabricated narrow-gauge crossings are individually designed, taking into account the track gauge, rail type, road category, and expected operational loads. The use of high-grade concrete and appropriately selected reinforcement types (traditional, hybrid, or composite) ensures a structure resistant to long-term эксплуатация.
CONTRACK technology enables:
-
production of a single prefabricated slab up to 17 meters in length;
-
adaptation of crossing slabs to the local geometry of the track layout, e.g. prefabrication on curves or with cant;
-
the possibility of manufacturing slabs with integrated intertrack areas;
-
integrated installation of rails and fastening components;
-
the possibility of adapting the surface finish (e.g. asphalt, paving blocks) to the road function;
-
compatibility with the prefabricated track surface technology system along the entire section.
Product advantages
Advantages of prefabricated narrow-gauge crossings:
- adaptability to various narrow-gauge railway track widths,
- rapid installation and reduced traffic closure times,
- installation of slabs without the need to dismantle overhead traction wires, using the PWP gantry system,
- reduction of the scope of works carried out on-site,
- reduced risk of execution errors in high-load zones,
- the possibility of local replacement of individual elements without interfering with the entire crossing structure,
- the possibility of phased execution of works while maintaining road traffic flow.
Modernization and maintenance
Prefabricated railway crossings designed with future operation in mind
CONTRACK technology is particularly effective in modernization projects, where minimizing interference with existing infrastructure and completing installation as quickly as possible are key priorities. Rails embedded in the prefabricated crossing slab can be replaced without dismantling the concrete surface, extending the structure’s service life. Rail replacement can be carried out in weekend mode, without interfering with the slab structure.
The system has been designed to reduce the scope of maintenance works and lower operating costs throughout the entire life cycle of the infrastructure.
Durability and Quality
Durability and Quality
The prefabricated elements are manufactured under controlled factory conditions, ensuring high geometric accuracy and repeatability of strength parameters.
The use of proven material technologies
(including solutions supported by SIKA) results in:
-
high resistance to dynamic loads and changing weather conditions,
-
increased durability of both the pavement and track structure,
-
long-term geometric stability during operation,
-
reduced risk of subbase degradation and deterioration in rail-adjacent zones,
-
high system tightness.
In addition, the system design enables efficient maintenance works without the need to interfere with the entire crossing surface.
