A rail vehicle includes a truck having wheels for engaging a railroad track, a bolster supported by the truck, and a tank supported by the bolster for storing a lading. A measurement system measures the level of the lading within the tank and includes gauges and a controller. The gauges are disposed at selected points on the bolster for sensing at least one of lateral and longitudinal localized displacement experienced by the bolster during motion of the rail vehicle. The controller calculates the level of the lading within the tank and compensates for changes in the level of the lading during motion of the rail vehicle in response to signals generated by the gauges.

Disclosed is a continuous measurement method for a wheel/rail vertical force. In a first unit measurement area, a second unit measurement area and a first-second compound measurement area formed by the first and second unit measurement areas, the method comprises: using measurement results of a first and a second shear force (Q.sub.1, Q.sub.2) measurement point and of one or more vertical support force (N.sub.j) measurement points of the rail sleepers between the first and second shear force (Q.sub.1, Q.sub.2) measurement points to obtain a wheel/rail vertical force (F.sub.1) applied to the first unit measurement area; using measurement results of the second and a third shear force (Q.sub.2, Q.sub.3) measurement points and of one or more vertical support force (N.sub.j) measurement points of the rail sleepers between the second and third shear force (Q.sub.2, Q.sub.3) measurement points to obtain a wheel/rail vertical force (F.sub.2) applied to the second unit measurement area; obtaining the wheel/rail vertical force applied to the first-second compound measurement area; and combining wheel/rail vertical forces applied by a wheelset to the first and second unit measurement areas and to the first-second compound measurement area to obtain a continuous wheel/rail vertical force of the wheelset. Further disclosed is a fully continuous ground measurement system for a wheel/rail vertical force.

A device and a method for weighing a roll of continuous web material on a spool at a weigh-ing station in a continuous process is described, which has fewer mechanical parts and is safer to use than prior devices and methods. The device is arranged adjacent to at least one of a pair of guide rails and comprises a damper and a load cell. wherein the load cell is integrated into at least one guide rail.

A railway track (1) including at least two railway rails (2) and at least one measuring apparatus (3), disposed under at least one of the railway rails (2), for measuring vertical contact pressure, wherein the measuring apparatus (3) has at least one mat-shaped or planar carrying body (4) with a multiplicity of measuring sensors (5), disposed at a distance from one another, for measuring the vertical surface pressure at the respective positions of the respective measuring sensors (5).

The present invention relates to a weighing module for measuring wheel contact forces of rail-bound vehicles, comprising a measuring rail and a number of strain gauges, wherein the strain gauges are applied directly on the measuring rail. The measuring rail comprises a load introduction region, made of at least one load introduction part, and at least two deformation bodies, which are connected fixedly in each case to a load output plate and, via a hinge, to the load introduction region. The strain gauges are arranged on the deformation bodies and capture the shear strain acting between the hinges and load output plates.

Transport rail system capable of detecting a weight of a rail vehicle, includes one or more rails, and one or more sensors for measuring a magnetic property. At least one of the sensors is adapted to measure a change of a magnetic property in order to determine a weight bearing on one or more of the rails, the change of the magnetic property being caused by stress exerted on the rail by the weight, and one or more of the sensors are adapted to measure the change of a magnetic property of the rail itself and/or that one or more of the sensors are adapted to measure the change of a magnetic property of a supporting structure of the rail.

The disclosed technology pertains to methods and systems for measuring and deploying mass transported by railway vehicles. A computing system may receive sensor data from multiple sensors coupled to a railway vehicle as the railway vehicle moves along a track. The computing system may use the sensor data to determine acceleration data and force data corresponding to the railway vehicle as the railway vehicle moves along the track. The force data represents a quantity of force applied to the railway vehicle to cause the railway vehicle to move along the track. The computing system may then estimate, based on the acceleration data and force data for the railway vehicle, a mass of the railway vehicle. The computing system may further use sensor data to determine that the railway vehicle is located proximate a drop zone and trigger an automatic release of cargo carried by the railway vehicle.
