No two modernisations are the same, this is why we address every customer need individually.
If the customer does not have a ready modernisation concept, we develop the project together until the concept is finalised. In the process, the necessary materials including all of the documents relevant for the approval are obtained directly from a single source. All of the work from the dismantlement to the integration of the modernised bogies in the vehicle is documented fully, adapted to our customers and always agreed in advance. We have the necessary equipment (washing plant, appropriate welding certification (CL1), blast cabinet, paint areas and crane installations) in order to carry out a bogie refurbishment completely independently in-house. Appropriate test equipment (cleanliness measurement, pressure test, function test, ISO measurement etc.) also provides the operator/TAB with full verification.

As well as building new vehicles, HeiterBlick can also refurbish (retrofit) fleet vehicles as required by upgrading components. We also sell body shells.

Our high-quality components such as bogies and coach bodies fit perfectly into any other manufacturing processes that may be required so that line operation may resume quickly. We have completed many such upgrading projects in recent years.

One example is the Pöstling mountain railway in Linz, Austria, which is considered one of the world's steepest long-distance adhesion railways.

Or the replica panoramic motor car for the rack railway along Lake Geneva in Switzerland between Montreux and Glion known as the ‘Marmot Line’. We supplied 36 new motor bogies with a 1,009 mm gauge to a transport company in the Bulgarian capital of Sofia, allowing 18 Tatra T8M vehicles to be upgraded.

We would be glad to help with your own upgrading projects and give you all the information you need about our extensive range of goods and services.
