Light Rail Vehicles: sailing smoothly through the traffic.

If cities wish to remain attractive places to live and offer cleaner air for their inhabitants, they need to implement alternative transportation solutions. Light rail vehicles are one such alternative – and Knorr-Bremse is helping to deliver these solutions. LRV lines are relatively easy to plan, take up very little space and are quick to build.

While all around them the traffic is at a standstill, quiet and zippy light rail vehicles sail smoothly through the congestion. Most important of all, these electrically-powered vehicles provide an environmentally-friendly solution. Light rail vehicles open up completely new development opportunities for urban planners. Well-designed routes can take over some of the important feeder functions of metro networks or provide rapid overground links between busy underground lines. Asian cities in particular have high hopes for this mode of transportation, which is comparatively new to their part of the world.

Overview

Take a look at our product portfolio!

Air Supply / Treatment

Compressor 'PistonSupply Eco'

Air supply systems supply the compressed air required by the braking system and other subsystems using screw compressors 'ScrewSupply' or oil-free compressors 'PistonSupply Eco', often in conjunction with adaptive control air dryer 'DrySupply Smart'.

Bogie Equipment

Bogie Equipment

In light rail vehicles, the brake force is generated by compact hydraulic brake calipers 'HydroAct Lever' and matching compact brake discs 'ProDisc Axle'. Electromagnetic track brakes 'MagnetAct Flex' and 'MagnetAct Rigid' allow the vehicles to operate in urban street traffic.

Friction Technologies

Friction Technology

Knorr-Bremse’s friction portfolio features the Propad Hydraulic brake pad, which has been specially designed for light rail vehicle applications.

Brake Control

Track Brake Control
Brake Control and Wheel Slide Protection
Magnetic Track Brake
'MotionLead family'

To achieve optimum braking, the optimal braking force must be applied to each axle and bogie. In light rail vehicles, this function is performed by electronic or hydraulic brake control systems, often in conjunction with the Modular Magnetic Track Brake Control 'MagnetControl'.

Hydraulics

Hydraulic Auxiliary Release Unit
Brake Caliper
Leveling Cylinder
Hydraulic Unit

Due to their limited installation space, light rail vehicles use hydraulic braking systems instead of pneumatic ones. These comprise electro-hydraulic control modules, hydraulic brake calipers, leveling cylinders, hydraulic auxiliary release units and hydro-pneumatic suspension systems.

Sanding Systems

Sanding System

Sanding systems can make a significant contribution to reducing light rail vehicle braking distances. The systems comprise sand boxes, sand dosing systems, sand pipe heaters, sand level monitors and sand flow sensors.

Wiper Systems / Wash Systems

Windscreen Wiper and Rainsensor 'VisionLead Electric'

Windscreen wiper and wash systems ensure that light rail vehicle drivers always have a clear view. Systems for light rail vehicles comprise wiper drives, arms and blades, control units, operating controls, washer water tanks, washer pumps and rain sensors.

Entrance Systems

Entrance System

Different entrance system configurations are available for light rail vehicle applications, depending on the application scenario and the operator’s requirements. The options include aluminum, full glass and stainless steel “sandwich” door leaves with obstacle detection. The systems also comprise door control units and door drives, ramps, gap bridges and sliding steps.
