Tunnel surfaces
Assess the cleaning task, materials and reachable surfaces.
TUNVORA · Railway Tunnel Services
We combine specialised cleaning technology with clear project coordination. For railway tunnels where geometry, access and operational requirements define the work.
01
Every tunnel presents different requirements. In the first discussion, we clarify the cleaning task, access and operational framework.
Assess the cleaning task, materials and reachable surfaces.
Review track construction, installations and contamination together.
Coordinate access, time windows, utilities and client interfaces.

02 / Technology
Configuration, cleaning unit and water management are considered for the specific tunnel. Binding performance figures will only be added from a current, approved data sheet.
Modules and working areas are assessed for the task.
The method is coordinated around surfaces, contamination and access.
Supply, routing and handling of water form part of project planning.
03
Record the task, tunnel and preferred timeframe.
Clarify technology, access and operational conditions.
Deliver the agreed scope on site.
Prepare records and handover as agreed for the project.
04 / Experience of partner Gruschina
A publicly documented project description names Dieter Gruschina as project manager for tunnel cleaning on VDE 8.1, Ebensfeld–Erfurt, in 2016. This note describes experience of partner Gruschina, not a contract completed by the new TUNVORA brand.
Experience05
TUNVORA is planned as a joint brand by Daniel Lagler, Günther Dobetsberger and Dieter Gruschina. It combines personal project coordination with the organisation and technology of experienced partners.
