Coupling simulator

Product Description

Modern railway systems have the possibility to build large and small train units according to the demand. Automatic coupling mechanism enable to link several individual units into an entire trainset. The leading vehicle controls the guided vehicle via electrical coupling. In addition to the control commands for braking and accelerating, other functions such as audio announcements or passenger information are transmitted.

The reliable function of the electrical couplings of a train ensures smooth operation in the multiple traction (driving with several coupled trains). This ensures the coupling function of a train with another train, the so-called test vehicle.

SPHEREA reduces this additionally required vehicle by the multiple traction test system viTra. viTra checks and verifies all functions transmitted via the clutch. The test system is connected to the electrical coupling of the vehicle and recognized as a coupled train. Depending on the application viTra assumes the role of a leading or a guided vehicle.

The modular design allows to expand with additional signal types and a fast adaptation to new vehicle types. The function oriented software and application concept makes it easy for the user to operate the device. Fixed acceptance reports are efficiently implemented by automatic test sequences. In manual mode, individual train functions can be tested in a targeted manner.

There is no need for an additional test person or an additional train with the viTra coupling test system. Without viTra two operators have to exchange manually the information, if the desired function has been performed correctly, between the individual driver’s cabs. viTra reports the results directly to the tablet used for control and offers an efficient way of performing the multiple traction test for operators and manufacturers. The flexible platform design provides the customer with a test system prepared for future tasks and extensions.
