Abstract: The present invention relates to a monitoring device for monitoring catenary-pantograph interaction in a railway vehicle (100) comprising a frequency-tunable radio receiver module (2) with its associated antenna (1) for the reception of radio signals (500) emitted by pantograph-catenary interaction in the radio frequency and microwave bands; and a control module (4) for detecting electric arcs (400) in the radio signal (500) received by the radio receiver (2) within at least one of the tuned bands. Information about the detected arcs (400) can be stored in the storage module (3) and used to generate records and/or alarms sent by a communication module (6). The radio receiver module (2) can be accompanied, in an input-output module (9) to facilitate pantograph monitoring and maintenance, by a pantograph current measurement module (8) and an odometry and positioning module (7) to obtain the position and speed of the vehicle.

Abstract: Metropolitan transport method and system that allows maximizing journey time commitment and network coverage by running a first train in a first direction, defined from a starting point to a finishing point of a route including a plurality of stopping stations, where the first train runs through a tunnel having two levels, the first train running on a first level of the tunnel and stopping at all the stopping stations on the route; the method also including running a second train in the first direction of the route on the second level of the tunnel, where the second train does not stop at all the stopping stations on the route.
Abstract: Section insulator for rigid catenary which has a dual functionality, since it can exercise the functions both of conventional section insulator and of neutral section insulator, configured so that it maintains a mechanical continuity which allows the smooth passage of the pantograph, minimizing the requirement for adjustment and maintenance. The insulator basically comprises a pair of conductor rail segments (2) between which is disposed a single central shoe (1) obliquely disposed with respect to the direction of the catenary, a pair of spark wires (9) wherein the electric field is broken and a series of strips (8) disposed on said central shoe (1) which, together with a bridging cable which extends from them to the conductor rail segment (2), enables bridging the wire conductor of the insulator (3) when one want to maintain the power supply to the pantograph.
