Railway technology products from Arnold
Arnold specializes in technologically complex assemblies that are used for
- trains,
- buses, and
- special/commercial vehicles.
This includes housings for power converters, batteries, and hydrogen engines as well as crash protection and design elements.
Engineering for railway technology products
Safety is a top priority when it comes to transportation products for passenger and freight traffic, and keeping the manufacturing costs low is a close second. So it is very important to emphasize cost effectiveness and competitiveness already during the development and design of your railway technology products.
Not only is it important to select the right materials, but also suitable manufacturing processes. Because even in production, the focus is always on cost savings in addition to the various DIN/EN standards and regulations.
Components for the interior and exterior of passenger and freight transport vehicles
As a system provider, Arnold realizes products that
- are installed in interior areas and have high design requirements,
- are integrated in machine rooms,
- are attached from the outside,
- and meet high safety requirements.

Certification and approval
We
- meet your desired design,
- handle project management,
- cost-optimize the product,
- construct and implement in our own metal production,
- integrate electronic components,
- coordinate with partners,
- work with all conceivable materials in addition to metal, and
- we have extensive test facilities, also in cooperation with partners (e.g., corrosion protection, IP protection, FEM calculation, vibration, or anti-graffiti)
Are you looking for a manufacturer of certification- and approval-relevant components for trains, buses, and special commercial vehicles or a system supplier to partner up with?
Please contact us.
Does Arnold process any other materials in addition to steel?
Yes. Arnold is a metalworking specialist that produces turnkey systems which are primarily made with steel and are combined and assembled with all conceivable materials such as wood, glass, and plastic.
As a system provider, what services does Arnold offer?
A system provider not only builds part of a complex product, he is also responsible for the integrated implementation of
- planning, production, coordination of all partners and the
- integration of displays, mechanical and electronic components through to the
- final assembly and
- delivery of the overall product.
What rail-specific approvals and certificates does Arnold have?
In addition to the regular standards for industrial suppliers (9001, 14001, 45001), Arnold is certified according to the following standards:
- EN ISO15085-2 CL-1 (welding): This standard is the basis for welding metallic materials in the manufacture and repair of rail vehicles and vehicle parts. It defines the quality requirements for the new construction of rail vehicles and their repair. Arnold has the highest certificate class CL-1 and is therefore allowed to manufacture components with high safety significance (welded joints of the weld seam quality class CP A to CP D).
- DIN 6701-A1 (adhesive bonding) : DIN 6701 (adhesive bonding of railway vehicles and parts) distinguishes between classes A1, A2, A3 and Z depending on the company's field of activity and the safety requirements of the bonded components. With the A1 certificate, Arnold is allowed to carry out bonding with the highest safety and quality requirements in rail vehicle construction.
Riveting vs. Welding: which is better?
Rivet constructions are generally used for lightweight designs, as thin metal sheets are used here without causing any distortions. Rivets are not suitable if a high level of tightness is required. But additional sealing is possible.
Unlike rivets, welding is used for large and heavy components or when tightness is critical. One of the disadvantages of this mating technology is that distortions may occur due to the introduced heat.
Welded constructions can be determined more precisely with FEM (Finite Element Method) compared with riveted constructions. This is particularly important for components that are subject to vibration.
