Ballastless Track – RHEDA CITY

METRO

Metro systems form the backbone of urban mobility. They connect different parts of a city quickly, safely and reliably, placing high demands on both infrastructure and track systems. In underground environments in particular, robust, low-maintenance systems are essential to ensuring consistently high availability. This is where RHEDA CITY comes into play.

Ballastless track is therefore becoming increasingly established in modern metro construction. Its long service life, low maintenance requirements and efficient construction processes make it the preferred solution for many operators. With RHEDA CITY, RAILONE offers one of the most established systems for this field of application. Continuously developed over nearly three decades, it now covers all typical applications in tunnels, on bridges and on other engineering structures.

TRAM

Trams are among the most popular modes of transport in urban areas. Compared with buses, they offer greater transport capacity and better environmental performance. As a result, many cities have rebuilt or significantly expanded their tram networks in recent years, repeatedly choosing the versatile RHEDA CITY ballastless track system.

Today, ballastless track is a proven and cost-effective solution for tram systems and has become an established alternative to ballasted track. RHEDA CITY is based on tried-and-tested technology and has been further developed in close cooperation with public transport operators to meet the specific requirements of urban environments.

With more than 25 years of operational experience, RHEDA CITY is one of the most widely used track solutions for tram systems. It can be flexibly adapted to different structural conditions and multimodal traffic areas, providing a high level of reliability across a wide range of applications.

THE CORE COMPONENTS OF RHEDA CITY

The RHEDA CITY system is based on a simple, standardized design comprising two main components that can be adapted and supplemented depending on the application. This clear structure simplifies planning, construction and tendering for public transport operators.

The core system components are:

• Bi-block sleepers with lattice girder reinforcement: for simple, cost-effective and precise rail positioning during installation, construction and operation
• Load-bearing cast-in-place concrete track slab: designed to accommodate traffic and rail loads while providing a high degree of adaptability, particularly in confined urban environments

BALLASTLESS TRACKS: ARCHITECTURE FOR THE URBAN ENVIROMENT

Ballastless track systems integrate seamlessly into traffic flows and the urban landscape, whether used for tram, suburban rail or metro lines. Systems covered with asphalt or paving can also be shared by buses and private vehicles. Green tracks offer an attractive alternative by adding valuable green space to the urban environment.

Ballastless track systems also provide outstanding ride comfort, high levels of safety and low maintenance requirements. In every application, they enhance Urban Transit and improve infrastructure quality. The future of urban mobility starts here!

RHEDA CITY - MAXIMUM FLEXIBILITY FOR DIFFERENT RAIL PROFILES, TRACK GAUGES, FASTENING SYSTEMS, TURNOUTS AND SPECIAL DESIGNS

Thanks to its versatile design, the system can be adapted to virtually all grooved and Vignoles rail profiles, track gauges and fastening systems. Continuous rail support is also possible.

For covered track, rail encapsulation systems and various chamber filling elements can be used depending on the specific requirements. This allows even stringent requirements for stray current control and noise protection to be met.

RHEDA CITY also provides solutions for different types of turnouts and special applications, including multi-rail systems. For sensitive urban areas, the system can also be designed as a mass-spring system with elastic support of the concrete base slab to specifically reduce noise and vibration emissions.
