Pneumatics for track machines - cylinders, valves and replacement components
We supply power and control pneumatic components for track machines, tamping machines, maintenance trains and rescue trains. We manufacture catalogue components, replacement components and custom-engineered designs adapted to the existing machine installation.
Where does pneumatics operate in track machines?
In track machines, pneumatics is responsible for actuator movement, control of working functions, locking and protection of assemblies and cassettes. Components operate under the vehicle and near the frame, in dust, moisture, vibration and variable temperatures. That is why they are selected differently than components for light automation: durability, environmental resistance, repairability and compatibility with the existing installation are critical.
CPP PREMA supports maintenance departments, repair facilities and users of special-purpose machines. We supply catalogue components, and where a standard product does not fit or the component is unavailable, we manufacture a replacement component or a custom-engineered design.
Machines and applications we support
CPP PREMA components operate in maintenance trains used for overhead contact line repairs, operated by companies involved in the maintenance, modernisation and construction of railway infrastructure, as well as in track machines and rescue trains.

Can you not see your machine listed? We also select components for ballast regulators, ballast cleaners and rail welding machines - based on a photo, drawing or sample component.
Pneumatic products for track machines
Special pneumatic cylinders
Rod-type, compact and round pneumatic cylinders, including special versions such as stainless steel piston rods, modified strokes, stronger magnets and reed sensors. They are used for driving and protecting assemblies and cassettes.
DTE series solenoid valves
Solenoid valves for remote cassette control and travel direction selection in maintenance trains. A replacement can be manufactured for a component that is no longer available on the market.
Directional control valves and check valves
Dedicated manually operated directional control valves and check valves - for controlling the direction and sequence of cylinder operation, pressure locking and movement control.
Filters and filter-regulators
Dedicated compressed air filters and filter-regulators - protecting valves and cylinders against contamination in demanding machine operating conditions.
Hydraulic cylinders
Hydraulic power where high force and rigidity under load are required - as a complement to the machine's pneumatic systems.

| Rolling stock and machine facility | Special compact cylinder, sub-base mounted valves and filters - returning customer | D50x35 cylinder, 24.0401.4312 SPM valve, 58.0001.12 filter |
Replacement components and regeneration of track machine components
Some track machine components are no longer manufactured or have non-standard mounting. We manufacture a replacement component that is functionally, dimensionally and mounting-compatible - without rebuilding the entire system - and we analyse the regeneration of worn cylinders and valves. The full scope is described on a separate page.
How to select a pneumatic component for a track machine?
- Component function Movement, control, locking, position holding or protection of an assembly or cassette.
- Medium and working pressure Installation parameters or a photo of the nameplate of the existing component.
- Operating conditions Installation location, dust, moisture, vibration, temperature and service access.
- Mounting and geometry Maintaining the plate, hole spacing, ports and stroke so that the component fits the installation.
- Behaviour after pressure loss What should happen to the lock, cassette or assembly - critical for safety.
- Service Availability of a repair kit and regeneration option to reduce downtime.

FAQ - pneumatics for track machines
What pneumatic components are used in track machines?
The most common components are special pneumatic cylinders, directional control valves and check valves, DTE series solenoid valves, as well as filters and filter-regulators. They perform drive, control, locking and protection functions for assemblies and working cassettes.
For which track machines do you select pneumatic components?
Among others, for UNIMAT and CSM tamping machines, REM 80 machines, PUN P9301 and WM-15P00 and PS00.M maintenance trains. We also select components for ballast regulators, ballast cleaners and rail welding machines based on documentation or a sample component.
Does CPP PREMA manufacture replacements for tamping machines and other track machines?
Yes. We manufacture replacement components that are functionally, dimensionally and mounting-compatible with the existing component, also for discontinued parts, without the need to rebuild the entire system.
Can a special pneumatic cylinder be ordered based on an existing component?
Yes. We manufacture special pneumatic cylinders based on standard designs - with modified stroke, piston rod, seals, magnet or mounting, adapted to the machine application.
Do you regenerate cylinders and valves from track machines?
We analyse the possibility of regenerating worn components and preparing a repair kit. The scope depends on the technical condition of the component after verification.
Do you have railway qualifications?
Yes. CPP PREMA has ISO 9001:2015 (TÜV), a certificate from the Rail Vehicles Institute “TABOR” and a CNTK qualification certificate accepted by the German Federal Railway Authority (Eisenbahn-Bundesamt).
