A chassis for a rail vehicle includes a chassis frame supported on at least first and second wheelsets and one A-frame linkage per wheelset on both sides of the chassis for horizontal axle guidance of the wheelset. Each A-frame linkage is connected in an articulated manner to one of two axle bearings of a wheelset by a wheelset-side bearing and to the chassis frame by two frame-side bearings. At least one of the bearings per A-frame linkage has a hydraulic bushing with variable longitudinal rigidity. The hydraulic bushing has at least one fluid chamber fillable with hydraulic fluid so that in the fluid chamber a hydraulic pressure can form for adjusting longitudinal rigidity. An acceleration sensor per axle bearing measures wheelset acceleration and an adjustment device adjusts hydraulic pressure in at least one of the fluid chambers depending on the measured wheelset acceleration.

A system that can automatically control the emissions of each locomotive in a consist to reduce overall train emissions. An emissions module determines the amount of emissions emitted by a train. An emissions control module commands the locomotive, via the train control system, to operate in a predetermined state to achieve a particular amount of emissions. A location module can track the location of the locomotive of the train relative geographic locations having emission regulations so that the emissions control module can command appropriate changes in the locomotive to reduce emissions.

In one aspect, a mobile railway asset monitoring apparatus is provided that includes a sensor configured to produce a signal indicative of a rotation of a wheelset of a mobile railway asset. The apparatus further includes a processor to receive data corresponding to a ground speed of the mobile railway asset. The processor is operably coupled to the sensor, the processor configured to estimate a running dimension of the wheelset based at least in part on the rotation of the wheelset and the ground speed of the mobile railway asset. The processor is configured to determine at least one parameter of the mobile railway asset based at least in part on the running dimension of the wheelset.

A warm-up system for an engine of a machine is provided. The machine has a primary alternator and an auxiliary alternator. The warm-up system includes at least one coolant heater configured to heat a coolant flowing through one or more coolant passages of the engine. The coolant heater is electrically powered by the auxiliary alternator of the machine when the engine runs at low load or idle conditions. The engine warm-up system further includes a thermostatic device operably coupled to the coolant heater and configured to control the operation of the coolant heater based on a temperature of the coolant flowing through the coolant passages.

A method for calibrating a device for measuring tracks having a track-driveable track-measuring car with a lifting and lining device and track-position measurement sensors measuring the height, direction and superelevation of the rails of the track using the machine frame as a reference zero line. A lifting and lowering device is associated with the track-measuring car. A calibration device is associated with the machine frame the track-measuring car, for calibrating the sensors, is first lowered from a parking position, in which the track-measuring car is lifted from the track, onto the track or into an intermediate position. Calibration stops are moved by an actuator from an idle position into a calibration position, against which the track-measuring car is subsequently raised and applied. The values of the track-position measurement sensors are read out and stored in the measurement system as calibration values, and the track-measuring car is lowered onto the track.
