    KEY TRANSMITTER

    Device used by railway operators for the safely maintenance of remote-controlled line stations; this function is ensured by the train traffic inhibition on the correspondent area commanded by the key that has to be extracted only after electrical approval given by the Traffic Line Manager. The device is normally installed in dedicated maintenance cabinets placed in the District Control Office.

    CONTROL BOARD FOR ELECTRICAL TRACTION AREAS

    Control board for electrical traction (E.T.) areas contains the necessary equipment for railway operators apt to safely manage the electrical traction area maintenance. In addition to the devices necessary to deactivate the E.T. areas, the cabinet contains a silk-screen printed panel with the topography of the areas and of the devices for the line locking. The cabinet may also contain small boxes with the keys for the deceleration along line and other ancillary equipment at railway operator disposal. Each device present in the control board is connected to the relays room and to the yard devices through sectioning terminal block normally placed in the lower part of the cabinet where they can be easily reached, checked and modified if necessary. The cabinet dimensions are defined by the technical design office and customized according to the available space in the District Control Office.

    LOCKABLE KEY TRANSMITTER

    Device used by railway operators furnish with a mechanical lock with a key normally locked by an electromagnet. The key can be extracted only after the electrical approval of the Traffic Line Manager and allows the manual shunting of the point switches. It is insert in a watertight box (in aluminium or in fibreglass) mounted on a dedicated mast, installed in correspondence with point switches.

    LOCKABLE KEY TRANSMITTER WITH DRIVING HANDLE OF THE SHUNTING BOX

    Device used by railway operators, furnished with a mechanical lock with a key normally locked by an electromagnet. The key can be extracted only after the electrical approval of the Traffic Line Manager and allows the manual shunting of the shunting box handle. The key could be inserting and lock only after the re-positioning of the handle, guaranteeing a safety condition of the device. It is insert in a watertight box (in aluminium or in fibreglass) mounted on a dedicated mast, installed in correspondence with point switches.

    DEVICE WITH YALE KEY

    Device used by railway operators which locks point switches into the normal position by electrical disconnection from the relay interlocking. The device’s lever, which is normally in the “released” position, will be moved to the “locked” position only after the relay interlocking impulse given by an inner electromagnet, allowing the lever to pass over the “waiting approval” position. When the lever is in vertical position, the yale key can be extracted, locking the lever and preventing any movement of the point machine. The point machine can be commanded by the relay interlocking only after the key re-positioning and the lever positioning on “released” status. As long as the lever is in the “released” or in “waiting approval” status, the key remains locked into the device. The device is insert in a watertight box (in aluminium or in fibreglass) mounted on a dedicated mast, installed in correspondence with station protection.
    TECHNICAL DATA
    The device has two applications:
    • • PERSONNEL SAFETY - It can be used to guarantee the maintenance personnel safety, working on yard station. Point machines’ lock in normal position keeps the tracks (on which personnel is working) free from traffic.
    • • PERMANENT MARSHALLING ROUTE - It can be used for the communication upsetting connecting a yard area with a centralized area. It avoids the sudden upsetting by a relay interlocking while a point machine is operating a marshalling route.
