HYUNDAI Rotem has signed a five-year framework agreement with Knorr-Bremse to supply hydraulic braking systems, doors, and heating, ventilation and air-conditioning (HVAC) systems for LRVs built by the manufacturer.

The framework agreement has a contract value “in the mid-double-digit-million euros range,” according to Knorr-Bremse, and it will be the first time that it has supplied all three key subsystems for this type of LRV. Starting in 2023 and continuing until at least 2028, Knorr-Bremse will supply equipment for over 200 LRVs for customers around the world.

Knorr-Bremse’s electro-hydraulic braking system features sanding gear and magnetic track brakes. The weight-optimised, low-maintenance entrance door systems will be supplied by the company’s IFE brand, while the modular, scalable, energy-efficient HVAC systems will come from Merak.

The new agreement, which includes contract extension options, follows previous successful cooperative ventures between Hyundai Rotem and Knorr-Bremse in the light rail sector.

“Knorr-Bremse is geared towards providing future-driven solutions for local mass transit services,” says Dr Jürgen Wilder, the Knorr-Bremse executive board member responsible for the Rail Vehicle Systems division. “South Korea, with its reputation as an innovation hub and trendsetter in modern transportation, is a highly relevant market for Knorr-Bremse.”

 “Apart from the purely technical advantages, this framework agreement provides opportunities for further synergies that will benefit both companies in the long term,” Wilder says.

Alstom order

Meanwhile Alstom has signed a framework agreement with Knorr-Bremse for the company to equip 130 regional trains for Germany with braking, door, climate control and toilet systems.

The contract has a value in the lower three-digit-million euro range, says Knorr-Bremse and is the company’s largest multi-systems order to date. The 130 Coradia Stream high-capacity EMUs have been ordered by the German state of Baden-Württemberg, and will operate in and around Stuttgart.

The contract, which will begin in 2023 and continue through to 2029, is for Knorr-Bremse to supply entire braking, door and heating, ventilation and air-conditioning (HVAC) systems for the trains.

It is also the company’s first contract in Europe to supply integrated toilet modules from its Evac brand, acquired in in 2021, to a major rolling stock manufacturer. Three toilet modules from the Evac SanSys range will be installed in each train.

The electropneumatic braking systems for the new trains will include PistonSupply Eco compressors, flexible braking control systems from the FlexControl Modular family, SysControl brake electronics and SandGrip sanding systems.

Knorr-Bremse will also be supplying pressure-tight, weight-optimised and low-maintenance doors with sliding steps from its IFE brand, and modular, scalable, energy-efficient HVAC systems for the double-deck trains from its Merak brand.

The order was placed under a long-term framework agreement concluded between Alstom and Knorr-Bremse in 2021 under which Knorr-Bremse is supplying equipment for all Coradia Stream trains ordered until 2025.
