BEING MOBILE - Rhomberg Bau

Railways without electrical engineering?
Although hidden from many, the benefits of this growing business field are felt by all
Temporary lighting in the emergency escape tunnel is important for safety. The colour green is
used to signal an exit.
Socket outlets, emergency telephone and
tunnel alarm system are integrated in a
communication and power distribution cabinet.
Most passengers who travel by train are unaware of the sheer level of electrical
engineering which goes on behind the scenes, particularly in railway tunnels.
The role of electrical engineering is to
equip tunnels, sections of track and
the associated operating buildings
with the required electrical systems.
Within Rhomberg Railway Technology,
we now cover a wide range of services
ourselves and not only provide the
equipment for our own large-scale
projects, but can also offer these
services to third parties.
Our range of services covers:
• Traction power 16.7 Hz
• Power supply 50 Hz
• Data networks and
telecommunications

Our services are also in demand
across the entire group of Rhomberg
