Construction of LB7 maintenance trailers

Production and modernization of maintenance trailers for the Hamburg HOCHBAHN.


Reinforcement of the Hochbahn fleet

Between 2021 and 2023, GBM Gleisbaumechanik Brandenburg/H. GmbH manufactured three type LB7 maintenance trailers and handed them over to Hamburger Hochbahn AG.

In addition, GBM has already modernized several LB7s for the transport company from Hamburg.

The four-axle, open LB7 maintenance trailers are used for the transportation of building materials and construction equipment as part of general construction activities within the HOCHBAHN subway rail network. The trolleys are suitable for loading from the front and can therefore also be used to transport midi excavators and other construction equipment in single-track tunnels.
