摘要： A system for securing a railway apparatus includes a support platform and a mechanism for securing the railway apparatus to the support platform, capable of switching from an unlocked state to a locked state. The securing mechanism has a guide rail, a trolley guided by the guide rail along a path which, when the support platform is in the loading position, is parallel to a reference plane, a device for immobilizing the trolley relative to the guide rail, an attachment member for attaching the railway apparatus secured to the trolley; and locking members for locking the guide rail relative to the support platform, which switch from an unlocked position to a locked position when the securing mechanism switches from the unlocked state to the locked state in the loading position of the platform, by urging the guide rail downwards relative to the support platform.

摘要： A cut and cover method of constructing grade separation structures includes partially burying precast substructure elements with associated trench boxes under live traffic. Once the precast substructure elements are buried, the substructure is completed and the bridge span is installed. Other methods include installing precast superstructure elements with a formwork system and forming a bridge substructure and excavating underneath the superstructure once the superstructure is formed.

摘要： A track renewal train comprised of a plurality of rail freight cars has coupled to its last car a bridge-like car having at respective ends thereof a rail-bound front undercarriage and a rail-bound rear undercarriage, and a track-laying bogie running on the ballast bed intermediate the undercarriages, the bridge-like car being supported with the front undercarriage on a track consisting of old ties and rails, on which the train moves in a working direction, and with the bogie on the ballast bed. Hoists are mounted on the bridge-like car for lifting separated sections of the old track and the lifted track sections are conveyed to selected freight cars. Simultaneously, new ties stored on the freight cars are conveyed against the working direction to the bridge-like car, successive new ties are lowered from the bridge-like car to the ballast bed, which has previously been planed, between the bogie and the rear undercarriage, the lowered new ties are laid on the planed ballast bed, new rails are laid on the new ties and fastened thereto.

摘要： The disclosure relates to laying railroad rail. The rail is placed on the unspiked tie plates of a roadbed. One end is fixed in place. Starting at the fixed end, successive sections of the rail are if necessary subjected to heat exchange to bring them to a predetermined temperature, relates to the mean ambient temperature of the locality where the rail is being laid. The necessary heating or cooling may be performed using means moved along the rail from the fixed end toward the free end. In order that rail may be laid at said predetermined temperature and while stress free, vibrations are imparted to the rail whereby any stress tending to develop in the rail from expansion or contraction, because of the temperature change, is relieved. The stress free rail at the predetermined temperature is then spiked in place and rail anchors are applied. By practice of the disclosed method, railroad track is produced which is stress free at said predetermined temperature and is uniformly stressed under other temperature conditions. These stresses are controlled by proper selection of the predetermined temperature used in laying operation.
