Track construction equipment needs to satisfy
high requirements. In Munich and Nuremberg,
DEUTZ engines are the driving force behind
several multi-functional vehicles.
INFO | Technical Regulations for Hazardous
The Technical Regulations for Hazardous Substances 554 (diesel engine exhausts) prescribe
special protective measures for work areas in which diesel engine emissions (DME) can occur.
The Technical Regulations for Hazardous Substances are published in the German Ministry for
Labour and Social Affairs's joint ministerial official gazette.

Whether it be a repair on the track bed, for instance, in a tunnel,
or the transportation of an underground train with an equivalent down
force weight of 125 tons over a steep ramp - the areas of application
for train vehicles are many and represent a real challenge for both
man and machine. Robel Bahnbaumaschinen GmbH, based in
Freilassing, Bavaria, is a manufacturer of multi-functional vehicles
that relies on safe and reliable drive systems from DEUTZ. Munich's
transport company MVG and Nuremberg's transport company VAG
recently deployed four track vehicles on the underground network in
the two cities.
They are practically unnoticed by passengers, since their work
usually starts at night. Whenever materials need to be transported,
faults need to be fixed, repairs need to be made to the track bed or
points or rails need to be changed, track vehicles are used on the
railways. This work can generally only be carried out on the infrastructure
of underground networks in major cities during brief nightly
periods of inactivity. The work vehicles, which look unusual
because of their large glass fronts, travel over both above-ground
and underground rail networks. To match their variable duties, they
are equipped with a range of application modules, for instance a
swivel derrick for loading and unloading track rails or an attachable
excavator grab for gravel work.
It is crucial that the work processes can be carried out within a
specific time window and can adapt with maximum capacity to the
spectrum of work that needs to be done. Consequently, flexibility, performance
and cost-effectiveness are what's needed. This also goes
for the drive system. Modified diesel engine performances and total
pulling power enable the work vehicles to precisely match the customer's
individual requirements. An individually-adjustable hydrostatic
drive system ensures precise adherence to the desired working
speed. A slow working journey is also possible, as is powerful towing
