Tram infrastructure
Prefabricated tram crossings
CONTRACK large-scale crossing plates are part of a system technology for dedicated crossings – long (up to 17 meters), double, or curved. They are designed for the efficient implementation and reliable operation of road and tram connections exposed to very intensive, heavy use.
About the product
Prefabricated tram crossings
The CONTRACK prefabricated tram crossing is a ready-made construction system in which the track and surface elements are prepared in advance in controlled production conditions and then delivered to the investment site for quick integration.
Unlike traditional methods, where the crossing is constructed in stages on site, here the key elements are pre-engineered and fitted as a whole. The reinforced structure accommodates intensive use, including heavy vehicular traffic.
Design
Dedicated Construction
Prefabricated CONTRACK crossings are manufactured in the dimensions and shapes specified in the design, adapted to the local track and road system. Advanced construction with traditional, hybrid, or composite reinforcement and a carefully formulated concrete mix ensure the durability of the monolithic structure, even under heavy use.
CONTRACK technology enables the construction of:
- up to 17 meters of length of one prefabricated slab
- adaptation of crossing slabs to the local geometry of the track system, e.g. prefabrication in a curve or with cant
- possibility of producing plates with integrated track spacer
- integrated mounting of rails and fastening elements
- the ability to adapt the surface (e.g. asphalt, cobblestones) to the road function
- compatibility with the prefabricated pavement technology system along the entire section
The entire system is designed as a coherent infrastructure element that eliminates problematic interfaces between different technologies.
Advantages of the product
Prefabricated tram crossings enable
- possibility of using lubricators in accordance with the design assumptions
- efficient implementation of development in critical infrastructure points
- laying the slabs without the need to dismantle the overhead lines using the PWP Gantry system
- obtaining a uniform surface along the entire length of the crossing and connection with the prefabricated section of the track using an inter-system insert
- limiting the scope of work carried out on the investment site
- high repeatability of prefabrication quality and precision of execution
- better traffic organization during works
- reducing the risk of execution errors in high-load zones
- quick replacement of worn-out track sections without damaging the reinforced concrete slab structure
Modernization
Prefabricated systems designed with future use in mind
CONTRACK prefabrication technology is particularly effective in modernization projects, where it's crucial to minimize disruption to existing infrastructure and complete construction as quickly as possible. The rails embedded in the prefabricated crossing slab can be replaced without damaging the concrete surface, extending its lifespan. Rail replacement can be performed on weekends, without disturbing the slab's structure.
Durability and quality
Durability and initial quality
Production under controlled conditions ensures high quality workmanship and repeatability of design parameters.
The use of proven material technologies (including solutions supported by SIKA) translates into:
- high resistance to dynamic loads
- durability of the track surface and structure
- geometric stability during operation
Additionally, the design enables effective maintenance work without the need to interfere with the entire crossing system.
Location
Prefabrication for key communication points
CONTRACK tram crossing prefabrication technology is best used in places of high communication importance, where traffic organization and infrastructure reliability are crucial, and where any intervention in the infrastructure directly affects the functioning of the city:
- railway and road intersections in city centers
- crossings with heavy car and tram traffic
- key journeys for efficient transport of materials for the operation of local enterprises
- transfer hubs and areas of intense urban traffic
- modernized infrastructure sections in dense development
