Rail vehicles have been used to transport goods and people for over a century. Due to population growth in metropolises and the transport revolution, rail transport has developed rapidly worldwide and now links cities all over the world. Enclosure systems from ROSE are used here to protect safety and functionally relevant technology in order to guarantee trouble-free operation. This makes them an important part of the railway industry.
We have been a system provider and development partner to the railway industry for many years and are very familiar with the requirements of the sector. We offer technical enclosures for a wide range of applications, which we customise depending on the area of use:
ROSE enclosures for railway technology withstand a wide range of external factors and environmental influences:
The robust die-cast aluminium enclosures are ideal for the installation of electromechanical components.
Glass fibre reinforced polyester enclosures are used in many industrial areas.
Stainless steel is becoming an increasingly important material in many areas of application.
Aluform enclosures are die-cast aluminium enclosures for I&C and automation technology.
The ROSE aluminium enclosures have been specially developed for use in harsh environments. They offer the following features:
The Aluform enclosure series, a further development of our standard aluminium enclosures, combines robust materials with a high design standard. This type of enclosure is particularly suitable for customised visualisation and input solutions in the visible area.
ROSE’s polyester enclosures for the railway industry meet the requirements of EN 45545 (fire protection in railway vehicles).
Corrosion-resistant, robust, durable: ROSE stainless steel enclosures are primarily used by our customers on tensile roofs or in underfloor areas. Here, the material proves particularly effective against external influences such as rain or stone chipping.
The quality and reliability of our products are particularly important to us. This is why ROSE enclosures are tested in external test laboratories in accordance with railway-relevant standards in terms of shock and vibration resistance as well as fire protection. This enables our customers to integrate our products into their systems with confidence and to rely on the technical properties and functionality in the various areas of application such as railway communication, vehicle construction or at railway stations and signal boxes. In accordance with the DIN EN 45545 test (fire protection in railway vehicles), our enclosures are suitable for use in areas with the requirements of hazard class HL 3.
EN 45545-1 is a standard for railway applications on the subject of fire protection in rail vehicles and contains the basic definitions and general rules according to which rail vehicles are categorised into operating and construction types. It also regulates the fire protection objectives.

EN 45545-2 describes requirements for the fire behaviour of materials and components.
These – as well as the paintwork – are subjected to the following four tests, among others:
This standard specifies the requirements for fire protection and the protection of human life for underground, above-ground and elevated fixed rail transport and passenger transport systems. The fire test according to the American standard NFPA 130 includes 2 individual tests:
In this method, there are special limit values for the optical smoke density, which are recorded after 1.5 and 4 minutes:
| Parameter | Limit value | Result PG 01 | Result PG 62 |
|---|---|---|---|
| Specific optical smoke density (Ds1.5) | 100 | 0 | 0 |
| Specific optical smoke density (Ds4) | 200 | 1 | 4 |
The limit value for this method is 35.
| Parameter | Limit value | Result PG 01 | Result PG 62 |
|---|---|---|---|
| Flame spread index | 35 | 0,7 | 2,2 |
All tests of product group 62 (and powder-coated metal enclosures) with regard to the paint structure were passed with flying colours.
