A device displays a course of a process of at least one railway safety unit. While using at least one device controller, process data supplied by the at least one railway safety unit, are converted by dual-channel processing into first and second image data of the course of the process to be displayed. The image data are output to be displayed on a data display unit. In order to simplify the displaying of the course of the process, a pair of display spectacles having a first and a second display is used as a data display unit. The first display displays a first representation of the first image data delivered thereto that is visually detectable by the right eye, and the second display displays a second representation of the second image data delivered thereto that is visually detectable by the left eye.

A magnetically clampable rail shunt (1) comprising two magnetic clamps (10), each clamp having a magnetic device for attaching the clamp to one of two parallel railway rails (R1, R2) of a railway track by magnetic force, and an electrical conductor (20) electrically connecting the two magnetic clamps (10) for shunting the two parallel railway rails. The rail shunt (1) is characterised by a variable electrical resistor assembly (30) for adjusting the electrical resistance of the rail shunt (1), said variable electrical resistor assembly (30) being connected in series between the two magnetic clamps (10) via said electrical conductor (20). Preferred application to testing of track circuits.

An improved switch point machine is provided which can seal out water, even if the machine itself becomes submerged. The operating rod and the point indicating rod that extend out of the switch box housing should be ground round and have a smooth surface for an improved seal. Those rods are preferably chrome plated. Dynamic hydraulic seals can be used to seal out moisture. Internal components, within the switch box housing, should also be sealed to be water resistant in the event water does enter the housing.

Method, system and software code for calibrating a rail track circuit comprising a plurality of rails coupled to form a track section having a predefined length, a transmit processing unit coupled to the track section at a first end of the track section, and a receive processing unit coupled at the second end of the track section. A transfer function between a transmit voltage applied by the transmit processing unit at the track section and a resulting receive current detected at the receive processing unit is first determined and then applied to the rail track circuit for automatic initial calibration or recalibration.

Systems and methods for detecting the dynamic train-to-rail shunting performance of a train as it is moving along the rails of a railroad track. The systems and methods use portable equipment temporarily installed at a site where it is desired to test the shunting of one or more trains or the electrical equipment installed at the track. The systems and method use sensor plates and a high speed recording system to simultaneously capture measured train-to-rail shunting characteristics and the positioning of a train's axles and any rail conditions impacting the measurements. The captured information can be used to fine tune the train, the electrical equipment installed at the track and/or to design new devices.
