A drone with railway driving capabilities has a drone body and at propeller arms. Each propeller arm has a propeller assembly having a propeller driven by a motor assembly. The propeller assembly of at least one propeller arm has a rotatably mounted propeller guard placed coaxially with the propeller. The propeller guard is shaped as a train wheel and is driven by the motor assembly. The propeller arm has an actuated joint for providing the propeller assembly with at least one rotation degree of freedom so that the propeller can be rotated between a flight mode and a driving mode and back. The flight mode involves a more horizontal orientation of the propeller assembly for providing an upwardly directed thrust force to the drone, in operational use, and the driving mode involves a more vertical orientation of the propeller assembly for allowing the respective propeller guard to drive on the railway track.

The present invention relates broadly to a railway track trolley (10) generally comprising a collapsible chassis (12), two pairs of wheels (14a/b) and (16a/b), and a platform assembly (18). The collapsible chassis (12) includes a pair of opposing beams member (20a) and (20b) interconnected by a pair of adjustable cross-members (22) and (24). The pair of wheels (14a) and (16a) are removably mounted to opposing ends of one of the beam members (20a) whereas the other pair of wheels (14b) and (16b) are removably mounted to opposing ends of the other of the beam members (20b). The railway tracks (26a) and (26b) may be separated at one of a plurality of predetermined track gauges and the collapsible chassis in an expanded condition is designed to match the required lateral separation of the opposing rail members (26a/b). The invention is also directed broadly to a gate catch assembly (90) generally comprising a coupling sub-assembly (92), and a catch sub-assembly (96) configured to be releasably engaged by the coupling sub-assembly (92). The gate catch assembly (90) may be installed in conjunction with the platform assembly (18) of the railway track trolley (10) of the earlier aspect of the invention.
