Devices and/or tooling systems for performing maintenance of dynamic weight management (DWM) systems on railroad vehicles are provided. In embodiments, the devices may include specialized devices or tools configured for removing and/or installing various DWM components. In embodiments, the removal/installation devices may include a DWM cover plate removal device, a DWM crank and shaft removal device, and/or a DWM bushing maintenance device. In embodiments, the DWM cover plate removal device may be configured to remove a cover plate of a DWM system attached to a frame of a truck assembly of a railroad vehicle, the DWM crank and shaft removal device may be configured to remove a DWM main shaft and/or a DWM chain crank from a DWM system, and the DWM bushing maintenance device may be configured to install and/or remove a frame bushing from and/or into a frame bushing opening within a frame of a DWM system.

A testing device for a railway bogie comprising a support structure adapted to support a beam, which is configured to be arranged transversely with respect to the rails of the railway bogie to be tested, wherein the testing device further includes at least one plate associated with said beam, at least one load application device associated with the at least one plate. In particular, the at least one load application device includes at least one planetary roller screw, having a first load application end facing in use towards the railway bogie, and actuation means configured to actuate the at least one planetary roller screw and enable application of a test load on the railway bogie.
