Exhaust Extraction Systems for Train Maintenance Depots

Industriestraße 13,
86405 Meitingen,

Blaschke exhaust extraction systems help to effectively protect employees from hazardous diesel exhaust emissions while maintaining and servicing diesel locomotives and railway vehicles.

For more than 40 years, Blaschke Umwelttechnik has been successfully designing and manufacturing exhaust extraction systems to control engine exhaust emissions from diesel powered railway vehicles in maintenance and repair depots. More than a thousand solutions have been installed across the globe.

Bespoke railway exhaust extraction solutions

An effective way to ensure clean air in train maintenance facilities is to capture the exhaust fumes directly at the source and to remove them before they are emitted into the environment.

Blaschke always finds an optimum solution adapted to the client’s specific needs and constraints. Each exhaust extraction system is individually projected and built so that it fits any type of service facility and diesel engine.

Stationary train exhaust systems

Blaschke offers three basic lines of exhaust extraction systems that may be transformed in an unlimited number of unique solutions.

A stationary system is an economical and space-saving local solution when only one diesel engine type or a specific train configuration is regularly serviced. The extraction unit is usually attached to the roof structure and the extractor hood may be lowered over the exhaust pipe at the predefined position using a remote control or a touchscreen panel.

Swivel arm systems for effective exhaust extraction

Mobile or stationary rotating exhaust extraction jib arms are designed for single or multi-track maintenance depots. The wall-travelling, wall-mounted or free-standing swivel arms reach up to 12m and are very flexible solutions. With the mobile or telescopic extraction units travelling along the jib, it is possible to service various engines at different places. The swivel arm systems can be used even in halls with built-in overhead crane systems or overhead lines. If required, a special safety mechanism precluding the simultaneous use of the exhaust extraction system and the overhead catenary is supplied. The height-adjustable and custom-built hoods guarantee that exhaust emissions are safely removed in any case.

Crane bridge exhaust systems for diesel railway vehicles

Overhead exhaust extraction bridges are a suitable choice where there are one or more very long rail tracks with various diesel engines being serviced at the same time. Blaschke exhaust extraction bridges are provided as a fixed or travelling system. The mobile, individually designed extraction trolleys moving along the bridges and across the rail tracks ensure a secure control over the length and width of the entire installation. A duct system supported by a suitable number of fans discharges the contaminated air to the atmosphere and makes sure that employees are not exposed to harmful diesel engine exhaust emissions when working.

Easy-to-operate train exhaust extraction systems

No matter if the exhaust extraction systems are manual or fully automatic, stationary or mobile, rotatable or moving, Blaschke Umwelttechnik focuses on ensuring that they work reliably for a long time and are easy to operate and maintain. Every single system is made to order and is produced by qualified and experienced staff according to international and German safety and quality standards. Blaschke’s client list includes world-renowned public and private railway companies.


The stationary RailPoint Exhaust Extraction System with vertically adjustable extractor hoods has proved itself through simplicity, reliability and the highest price-performance efficiency.


A wall-guided MobileSwivel-Arm Exhaust Extraction System is the ideal solution for very long maintenance and repair depots of diesel-powered railway vehicles and when various diesel engines must be serviced at one time.


With the RailBridge-System, Blaschke Umwelttechnik is providing a practical and universal overhead solution to keep workers safe as required under many health and safety standards and regulations.


The RailBridge-Crane Exhaust Extraction System is suitable for providing large buildings with crane systems.

German Blaschke Umwelttechnik Presents Modern Solutions for the Extraction of Diesel Exhaust Fumes at InnoTrans 2016

At InnoTrans 2016 in Berlin, Blaschke Umwelttechnik presents new solutions for the extraction of diesel exhaust fumes. The modern extraction systems protect employees in train maintenance depots reliably against the harmful emissions from diesel trains and locomotives. At booth 607 in Hall 23, the Germany based company also provides information about its entire product range.

Blaschke Launches Revamped Website for its Exhaust Extraction Systems

In the future, Blaschke would like to inform you more quickly and comprehensively about its products and projects. Therefore, we have revamped our website technically, visually and in content to provide a modern appearance; larger, more numerous pictures; and simpler contact options.
