Abstract: An onboard system transmits a train occupancy range based on a measured train position to a ground system. The ground system provisionally detects the occupancy state of each block section based on the train occupancy range acquired from the onboard system. Exit detection points (Qh, Qr) are set at a position outside each block section. It is determined that the train has left the block section when the entirety of the train occupancy range has passed the exit detection point (Qh, Qr). When the provisional detection result indicates that the detection target block section is not occupied, and it has been determined that the train has left the detection target block section, it is determined that the detection target block section is not occupied.

Abstract: A device and method for suspending or holding down an overhead contact wire used for supplying power to electrical railway vehicles and trolley buses at the crest of a vertical curve where the contact wire has an abrupt change in line angle. The device smoothes out the abrupt angle into a curve, parabolic in form and of a radius that is smooth for trouble-free operation of current collectors while maintaining elastic suspension. Contact wire uplift continues while passing through the device so that there is an avoidance of hard spots which cause uneven and accelerated contact wire wear. The device can further be used at the crest of a vertical curve to maintain contact wire alignment where a horizontal curve with curve pull is encountered concurrently.

Included in the traction enhancing system is an air nozzle associated with at least one of the traction wheels, mounted directly or indirectly relative to the frame so that an outlet of the air nozzle is directed at a corresponding rail of the railroad track for emitting high pressure air for removing at least one of unwanted debris and moisture. In addition, a scraper blade is associated with the nozzle and mounted relative to the nozzle so that the scraper blade contacts debris on the track before the high pressure air, in a direction of travel of the mover.

Abstract: Railway stone ballast and related systems and methods are provided. A representative railway stone ballast includes a crushed stone matrix; rubber aggregate; and an adhesive binder adhering the rubber aggregate to the stone matrix.

One or more sensors (151a, 151b) are disposed at the vehicle (1) and are intended to be able to sense the presence of and the orientation of a track or groove (51) and transfer sensed information to a power control circuit (100), which is adapted to comprise a control circuit (100b), which when sensing the existence of and a sensed orientation of a track or groove (51), within a covered and restricted area, is to be adapted to actuate means (7) adapted to a sidewise movement and/or a lowering (or raising) movement at the contact means (4).

Abstract: A cabin for accommodating at least one of passengers and goods, including an opening and a holder fastened to the cabin for holding a glazing unit in the opening. The cabin includes at least two connection members that each include a first fastening part connected to the glazing unit and a second fastening part connected to the cabin. The glazing unit is secured in the region of the opening when the glazing unit has detached from the holder. The glazing unit can, for example, be pressed out of the holder as a result of persons carried in the cabin violently pushing or striking the inner side of the glazing unit. However, the connection member prevents these persons from falling downwards out of the cabin. The glazing unit is also prevented from falling. As a result, safety of the passengers and/or goods in the cabin is ensured.

Abstract: A method is provided for detecting broken rail, unintentionally misaligned turnouts, and track occupancy ahead of or behind a railway vehicle traveling on a railroad track. Shunts extend between the rails at intervals along the railroad track. Each shunt has electrical signal transmission characteristics differing from those of adjacent shunts. A test unit on the railway vehicle induces a test signal in a first rail to create a track circuit in which the test signal propagates along the first rail, through at least one of the shunts, returns to the railway vehicle along the second rail, and through the wheels and axle of the railway vehicle. The test signal has electrical properties selected to interact with at least one of the shunts. The received test signal on the second rail is analyzed to identify predetermined conditions concerning the status of the railroad track.

Abstract: The invention relates to a switch and to a method for transporting and installing such a switch, which is equipped with longitudinal sleepers, the sleeper sections (2, 3) of which are or can be coupled in a flexurally stiff manner by means of a connecting device (16) embedded in the sleeper heads (4) so that the switch can be folded for space-saving transport. The divided longitudinal sleepers are oriented relative to each other and installed in such a way that the joints of the longitudinal sleepers are aligned along a straight line, which thus can serve as a rotational axis for folding up a side of the switch. The joints aligned on the rotational axis act similarly to a hinge band so that complete switch segments, such as a switch end part or the core region, can be folded along the line.
