Maintenance & Service

High flexibility for our customers

We add our flexibility in the field of maintenance and service to our high manufacturing and testing standards related to electrical components. The maintenance and service works range from the procurement of spare parts to the maintenance of complete railway passenger cars and special freight wagons at our customers‘ premises.

Service paves the way to the future

The RWS company agrees upon the extent and manner of their service works by concluding long-term contracts with their customers – we have been servicing the sleeping cars and the couchettes of the Swedish State Railways (SJ) which run between Berlin and Malmö for more than ten years, for example.


Upon consultation with our customers our mobile maintenance team will be able to come to each site accessible by car with a mobile emergency generator in order to do maintenance work and perform functional tests of electrical systems in railway vehicles.

The testing process of periodic inspection of electrical equipment will be carried out in accordance with:

  • DIN VDE 0701 – 0702 and the operational instructions under BGV A3.

Of course, all work done will be documented and subsequently handed over to the customer as a test report.


Our mobile service teams can promptly repair any defects found in the course of the respective maintenance work. Therefore, we permanently keep a wide range of spare parts available in our service vehicles. If a special spare part is required we will see about getting it to site as soon as possible.

After prior agreement we also offer mobile services at any place accessible by vehicle. 

If we are contracted to do the maintenance and the services for an electrotechnical system for a minimum of six month we will automatically keep the error statistics. We will analyse weak spots and evaluate them with the customer.
