EP COMPACT IN HIGH-SPEED TRAINS,
MULTIPLE UNITS AND METROS
The modules of EP Compact offer a wide range of functionality, such as the integration of distributor valves for the fully
load weighed indirect brake, wheel slide protection, parking brake and magnetic track brake actuation. Each function is
an add-on to the core module, which forms the brake control sub-system for a single car or an individual bogie. These
sub-systems provide the basic modules for the full brake control system. Full electronic information exchange is ensured
between the EPC units via the option of a dedicated Brake-bus. Connection to a wide range of state of the art train
information networks like MVB, Ethernet and CANopen is also available.
THE EP / BP COMPACT MODULES – THE BASIC UNITS
The EP Compact unit comprises two main elements: a modular pneumatic control unit PU and an optional electronic
control unit CU / GCU. The two elements PU and CU are compatible, although they remain physically separate in order
to provide the flexibility for incorporating them into the vehicle and for maintenance purposes. For extended interfaces
to the vehicle control system an optional gateway unit GCU instead of the CU can be provided to facilitate additional
high functionality with CAN-bus systems and discrete control lines.

THE PNEUMATIC UNIT PU
The pneumatic unit PU of EP Compact incorporates the entire pneumatic actuation and sensor-components. It
provides a modular system of pneumatic functions such as BCP control (PU-C, Lite), WSP (PU-W), parking brake
control (PU-P), magnetic track brake actuation control (PU-M) and as a feature the integration of a distributor
valve (KKL / STV) for the indirect brake.
THE CONTROL UNIT CU
EP Compact can optionally include a Control Unit (CU), which provides the electronic control and monitoring of
the PU, especially the pressure control, WSP and diagnostics. Apart from these control functions, the CU can
acquire and process all related external data such as the handle position of isolating cocks or external pressure
switch signals. In addition, a variety of inputs are available for train line signals.
THE GATEWAY UNIT GCU
The Gateway Unit (GCU) optionally provides an extended interface between the brake control system and the
train control system. Consequently, the brake management is accomplished in the GCU, which contains the
interface to the train management system and additionally carries out coordination of the brake functions. By
means of extension boards which allow almost unlimited scaling of the IOs, the GCU can be adapted to the
control system of the vehicle. The GCU performs the centralized and train system functions such as brake
management and diagnostics.
THE BP COMPACT MODULE
BP Compact can deliver electronic brake pipe control in accordance to
UIC541-03 and STM-F301. It includes a rapid charge function as well as
assimiliation according to UIC. It can be used for different applications because
