The railway vehicle bogie, comprising a body and two axles, the body comprising two beams extending in a longitudinal direction, each axle comprising a pair of wheels each provided with a tire and a connecting device extending between said wheels, each axle comprising an axle box extending in a transverse direction substantially perpendicular to the longitudinal direction and at least partially surrounding the connecting device. The beams of the body are connected to each other by the axles, the axle box of each axle being rigidly fixed to each of said beams.

A highly efficient, utility scale energy storage system employs large masses transported uphill to store energy and downhill to release energy. An electric powered cable winch or chain drive shuttles the masses between two storage yards of different elevations separated by a steep incline on rail vehicles supported by track and operated by an automated control system.

Device for attaching a cabin designed to be hauled by a cable, including a fastener to couple the device to the cable, and at least one arm configured to attach the cabin in removable manner and mounted mobile on the fastener to move the cabin with respect to the fastener.
