Abstract: An unmanned tactic platform (UTP) mounted on a two-stage locomotive system of which a first locomotive stage is a significantly high-speed travel stage where the UTP reaches an arena, and a second locomotive stage is a tactical maneuver stage in which the UTP maneuvers at the arena for executing a mission.

Abstract: A de-railed railroad car is replaced onto a track by removing a knuckle from a coupler of the derailed railroad car and replacing it with an adapter member. The adapter member is attached to the coupler by the same pivot pin that held the knuckle. By then raising the adapter, the wheels of the de-railed railroad car can be lifted. By then moving the adapter horizontally, the wheels can be placed over the track, so that when the adapter is subsequently lowered, the wheels will be placed onto the track.

Abstract: Disclosed is a rerailer apparatus that can be installed in a rail car for rerailing the rail car if it derails. The rerailer includes two vertical lifting members which are suspended from the rail car and are connected to a foot. These lifting members are used to lift the rail car vertically when the lifting members are extended and the foot contacts a support surface. A lateral movement member integrated with the vertical lifting members and the foot is used to move the lifted rail car laterally.

Abstract: A re-railing unit for re-railing a derailed rail car comprises a base, two stabilizer rams located at opposite ends of the base, and a port plate slidably mounted on the base. The support plate carries a pair of vertical lifting rams from which is suspended a vertical lifting arm. The bottom of the lifting arm is hook-shaped to engage the underside of a rail car drawhead. The lifting arm raises an end of the rail car in response to extension of the lifting rams. A shifting ram then slides the support plate across the base to reposition the rail car wheels over the track. The lifting arm is lowered to enable the wheels to rest upon the track.

Abstract: A device for rerailing a tool frame having first and second flange wheels onto the rails of a track, the tool frame being movably connected to a machine frame of a track laying machine, the rerailing device comprising a pair of levers mounted directly on the tool frame for abutting against the rails, a swivel drive for swivelling the first and second levers in a plane extending perpendicular to the longitudinal direction of the track, and a spreading drive connected to the tool frame capable of assuming a blocking position in which the position of the tool frame is fixed and a floating position in which the position of the tool frame is adjustable.

Abstract: An apparatus for placing a carriage linked to a frame of a track working machine on a track comprises a rail sensing element mounted on the carriage for sensing a respective track rail, the rail sensing element being positioned in the radial plane of the flanged wheel when the carriage is placed on the track and emitting a control signal in this position. A hydraulic drive for displacing the carriage transversely with respect to the track links the carriage to the track working machine frame. In response to the control signal, the operation of the hydraulic drive and the transverse displacement of the carriage is interrupted.

Abstract: A self-centering truck assembly is intended for use on model-railroad cars. Model rail cars have some form of truck-mounting structure thereon which provide a way to mount trucks to the car. A truck is provided which includes an elongate bolster extending between its sides. A self-centering cam is provided and is operable to center the trucks such that the bolster axis is oriented normal to a longitudinal axis of the car.
