Slinding vane rotary combustion chamber engine. Vanes (12) are actuated by trunnions (13.1) running in lift (24.1) and retract cams (24.2). Volume between vanes (12), end plates (24) and rotor (11) varied by profile on stator (21) inside surface (21.1). Knock-free, low emission and complete combustion ensured at high compression ratio by suitable combustion chamber (11.1) geometry. Low volume quench zones enable high combustion efficiency. Seal lubrication in combustion zones made possible by local cooling and inter-seal flushing: the oil layer on the stator (21) inner surfaces (21.1) is constantly swept into oil exhaust passages in the vanes (12) thence to cool and cool oil constantly laid down on the stator inner surfaces (21.1). Vanes (12) themselves are oil cooled.

Train integrity is confirmed using GPS equipment, in a method characterised by the steps of selecting a spot on a track, detecting the co-ordinates of that spot, storing those co-ordinates, detecting the GPS co-ordinates at the end-of-train (EOT), comparing the EOT GPS co-ordinates with the spot co-ordinates and reporting a train integrity if and only when the EOT GPS co-ordinates match the spot co-ordinates. The co-ordinates of the spot are preferably detected by an additional GPS located in the cab or locomotive at the front of the train. Thus when the end of train GPS co-ordinates match the spot co-ordinates, it will be apparent that the end of train has also passed that spot.

This invention relates to a foot guard. More specifically, the invention relates to a foot guard with a lace guarding member that protects the laces attaching the foot guard to wearer's shoe from being severed or burnt, thereby preventing the foot guard from falling off the shoe and exposing the wearer's feet to injury. The foot guard includes: a protective plate member being sized and shaped to cover and protect that portion of a shoe housing the metatarsal region of a wearer's foot, the protective plate member defining a plurality of lacing apertures through which the lace of the shoe is threadable for the purposes of releasably securing the protective plate member to the shoe; and a lace cover member for covering the lacing apertures and the lace securing the protective plate member to the shoe; such that, in use, the lace is sandwiched between the protective plate member and the lace cover member thereby protecting the lace from being severed and/or burnt, so as to prevent the foot guard from falling off the shoe and exposing the wearer's shoe and/or foot to damage and/or injury respectively.
