Systems, devices, and methods are presented for securing a railroad tie atop a support. In one implementation, a unitary length of metal rod is made into a clip that includes a vertical leg, a horizontal leg, and a resilient hook-shaped portion having a hook point. The hook-shaped portion is made so that the clip is biased toward a seated position, with the hook point positioned beneath part of the support. During installation, the vertical leg is placed through a hole in the railroad tie, driven downward until the resilient hook-shaped portion collapses into a compressed position, and driven further until the hook point moves beyond a free edge of the support and expands into the seated position. The clip secures the railroad tie without any additional parts and without requiring a worker to labor beneath the support.

A cargo container loading and unloading system for a transportation system, the cargo container loading and unloading system including a loading zone; and at least one opening connecting the loading zone to a transportation tube of the transportation system.

A double-walled tube section for constructing a double-walled tube segment suitable for underpressure applications such as an evacuated tube transport system.

A high-speed transportation system, the system including at least one transportation path having at least one track, at least one transportation vehicle configured for travel along the at least one transportation path, a propulsion system adapted to propel the at least one transportation vehicle along the at least one transportation path; and a levitation system adapted to levitate the transportation vehicle along the at least one transportation path. The at least one transportation vehicle additionally comprises wheels for at least intermittently supporting the transportation vehicle on the at least one track.

A train station has at least one transportation route for traffic of vehicles, wherein the at least one transportation route is provided with a vehicle tunnel. At least one public waiting area is arranged adjacent to the at least one transportation route. An enclosure is provided in which the at least one public waiting area is arranged, wherein the enclosure has at least one side wall. At least one ambient air purification arrangement for purifying ambient air is provided that has one or more filter units for separating solid, liquid or gaseous ambient air pollutants from the ambient air. The one or more filter units are arranged at and/or in the at least one side wall of the enclosure.

A point switch is designed such that the point plates (1, 2) of the point switch which support the track (11, 12) are placed vertically on top of one another and that the position of the points is set by vertically moving the point plates.

A protective coating system for a railway structure having a waterproof membrane and a ballast mat. The waterproof membrane is disposed on the railway structure. The ballast mat further has a ballast protection coating and a sealing layer. The ballast protection coating is a rubber compound and is disposed on the waterproof membrane. The sealing layer is disposed on the ballast protection layer.

The present invention relates to a process and to a system for laying tracks for ballastless railway and tramway lines, both in tunnel and in surface.

A method of monitoring tube integrity of a high-speed transportation system. The high-speed transportation system includes at least one tube structure having at least one track, at least one capsule configured for travel through the at least one tube structure between a plurality of stations, a propulsion system adapted to propel the at least one capsule through the structure, and a levitation system adapted to levitate the capsule within the structure. The tube structure is maintained as a low-pressure environment. The method includes directing a vehicle having at least one sensor along a tube path; and detecting a plume of air leaked from the low-pressure environment using the at least one sensor.
