A railcar bogie includes: a cross beam supporting a carbody of a railcar; an axle box including a bearing accommodating portion accommodating a bearing rotatably supporting a wheelset; a plate spring extending in a car longitudinal direction while supporting a car width direction end portion of the cross beam; and a receiving member provided above the axle box and supporting a car longitudinal direction end portion of the plate spring, an attachment hole being formed at a car longitudinal direction outside portion of the receiving member, a lifting fitting used to lift the bogie being attached to the attachment hole.

A railcar bogie includes a bogie frame including a cross beam and supports, the supports disposed at respective car width direction end portions of the cross beam. There are a plurality of axle boxes to accommodate a plurality of bearings supporting a pair of axles, a plate spring extending in a car longitudinal direction and supported by a pair of the axle boxes which are away from each other in the car longitudinal direction among the plurality of axle boxes. The plate spring supports the cross beam while being pressed by the corresponding support from above such that the pressing member is separable from the plate spring. Elastic walls are at both respective sides of the supports in the car longitudinal direction and sandwiched between a lower surface of the bogie frame and an upper surface of the plate spring so as to be compressed.

Disclosed is a method for controlling the position relatively to a platform of a floor of a carriage including a bogie including a chassis, a primary suspension, and a secondary suspension, the method including the steps: measuring the height of the secondary suspension; and adjusting the height of the secondary suspension, according to the height of the platform for positioning the floor at the height of the platform. This method includes a step for estimating the height of the top of the chassis, the adjustment of the height of the secondary suspension being achieved according to the estimated height of the top of the chassis.

The invention relates to a bogie (1) for a guideway-bound levitation vehicle (7) of a magnetic levitation system, with two rows (21, 22) of multiple levitation frames (2) spaced apart from each other in a transverse direction (Y) of the bogie (1) and extending in a longitudinal direction (X) of the bogie (1), with at least two cross members (3) spaced apart from each other in the longitudinal direction (X) and extending in the transverse direction (Y) and connecting the two rows (21, 22) of multiple levitation frames (2) to each other, with at least one longitudinal member (4) extending in the longitudinal direction (X) and connected to the cross members (3), and with at least one receiving means (18) for receiving a vehicle compartment (8) of the levitation vehicle (7). According to the invention, two longitudinal members (4) spaced apart from each other in the transverse direction (Y) are arranged between two cross members (3) spaced apart from each other in the longitudinal direction (X) and are connected to these two cross members (3) The invention further relates to a bogie.

The present disclosure discloses a rail vehicle. The rail vehicle includes: a bogie, where the bogie has a straddle recess suitable for straddling a rail; and a vehicle body, where the vehicle body is connected to the bogie and pulled by the bogie to travel along the rail, and the vehicle body includes a plurality of compartments hinged sequentially along a length direction of the rail; and in the length direction of the rail, a surface of a compartment at at least one end of the vehicle body and facing away from an adjacent compartment is provided with an escape door that can be opened and closed. The rail vehicle according to these embodiments of the present disclosure facilitates optimization the structure of an escape passage, reduction in costs, reduction in occupied space and the weight borne by the rail, and improvement in stability.

A method of assembling a railcar bogie includes: a plate spring arranging step of making a pair of axle boxes support a plate spring extending in a car longitudinal direction, the axle boxes being arranged away from each other in the car longitudinal direction; a bogie frame arranging step of placing a bogie frame directly or indirectly on a longitudinal direction middle portion of the plate spring from above, the bogie frame including a side wall on which an opening is formed, the side wall covering the plate spring from an outside in a car width direction; and a measuring step of measuring a positional deviation between the plate spring and the bogie frame in the car longitudinal direction through the opening.

Vessel transfer systems are provide herein. The systems include bogies, including a pivoting bogie and a rack and pinion bogie, as well as associated cradles, carriages, and power and control units. The pivoting bogie includes a first side frame, a second side frame, at least one wheel coupled with each of the first and second side frames, and a lift member coupled with each of the first and second side frames. The lift member is pivotably coupled to the first side frame. The rack and pinion bogie includes a frame and pinion gears coupled with the frame. The pinion gears can be selectively coupled with a gear rack, such as at a shipyard. Also provided herein are methods of use of one or both of the bogies and associated equipment, such as for moving vessels within a shipyard.

A Rail Drone can include: a payload interface, a drivetrain, and a rail platform 515. The Rail Drone can additionally or alternatively include any other suitable set of components. The Rail Drone can integrate a standardized payload interface and an autonomous electric road vehicle platform into a rolling stock architecture. The Rail Drone can be a stand-alone, payload-agnostic, motive element which can be independently or cooperatively capable of carrying heavy loads across long distances at various cruising speeds.

A railway vehicle condition monitoring apparatus includes a detection device for detecting vehicle information represented by a wheel load or the like of a wheel included in a railway vehicle running on a railroad track, and a determination device including a classifier to which the vehicle information detected by the detection device is input and which outputs a vehicle condition such as the presence or absence of an abnormality of the railway vehicle. The classifier is generated by means of machine learning that uses training data of a railway vehicle of which the vehicle condition is known, the training data being the vehicle information and the vehicle condition which is known, the machine learning being performed so that when the vehicle information of the training data is input to the classifier, the classifier outputs the vehicle condition of the training data.
