unit drivers and two for other personnel. One of each of these two types was mounted on a truck, to
enable them to be used flexibly and independently of location.
For the Norwegian Rail Academy Sydac also developed state-of-the-art simulators that realistically
simulate the FlytoGet line in the Norwegian capital of Oslo. The Norwegian Rail Academy ordered six
full cab simulators and three additional ones for operations control.
2010 also saw Sydac further expand its cooperation with TDS (Train Dynamic Systems), a company
owned by Knorr-Bremse subsidiary New York Air Brake (NYAB). The main focus was on merging simulation
of heavy-duty freight trains from North America with Sydac’s simulator technology for passenger
operations.
Further development of EP2002 brake control system
Knorr-Bremse has launched the EP2002 Cube brake control system for metros and multiple units. Based
on the proven EP2002 brake control system, the Cube features an additional integrated control module.
The mechatronic system, which combines mechanical and electronic elements in a single, ultra-compact
unit, now not only offers the service and emergency brake functions of EP2002 but also additional
pneumatic functions for controlling the parking brake and air suspension. As a result there is no longer
any need for an additional, separate control panel.
In the past, auxiliary functions such as air treatment or parking brake control have been installed in
brake control modules in sub-frames or on equipment panels. This is where the EP2002 Cube makes a
real difference. The Cube is basically a three-dimensional aluminum block with no active functional elements
of its own that fills the roles of the conventional EP2002 assembly subframe, the connector block
and the piping, effectively making it a three-dimensional multifunctional component. All of the components
required for the above functions are attached to the Cube. The multiple air lines encased
within the aluminum block mean that except for the compressed air feed pipe and the lines to the
mechanical brake components, air spring components, and reservoirs, all of the piping in the vehicle
can be dispensed with. Even then, the installation envelope of the Cube is no larger than the crosssection
of an average air reservoir. This simplifies integration of the brake control system, enabling it to
be installed beneath the car within a length of just 400 millimeters.
Advantages like these have greatly accelerated the market penetration of the new EP2002 Cube. By the
end of the year under review some 700 units had already been installed in metro projects in China.
New E3D door system
During the year under review, Knorr-Bremse’s subsidiary IFE developed a new door system for trains
travelling at speeds up to 300 km/h. E3D is an electrically operated single-leaf door system that combines
the familiar E3 and DET door systems. It is supplied almost completely pre-assembled and features
a compact installation envelope and easy maintenance.
