  2. Railway coupling - Wikipedia

    en.wikipedia.org/wiki/Railway_coupling

    As of 2020 Wabtec is working on an Digital automatic coupling (DAC) based the Schwab coupler, a possible replacement of the screw couplers in the European rail freight service. [33] The coupler is able to handle tensile forces up to 1500 kN and compressive forces up to 2000 kN and is therefore one of the strongest couplers ever designed for ...

  3. Janney coupler - Wikipedia

    en.wikipedia.org/wiki/Janney_coupler

    With gooseneck couplers or offset shank couplers, the horizontal centerline of the coupler head is above the horizontal centerline of the coupler shank, or shaft, and the draw gear. This arrangement is designed for use with low-floor freight cars , to lift the coupler head high enough to match the couplers on other rolling stock. [ 18 ]

  4. Tightlock coupling - Wikipedia

    en.wikipedia.org/wiki/Tightlock_coupling

    Type H Tightlock couplers are a variety of Janney coupler, typically used on North American mainline passenger rail cars. They have mechanical features that reduce slack in normal operation and prevent telescoping in derailments, yet remain compatible with other Janney types used by North American freight railroads. Like all Janney couplers ...

  5. Railway coupling by country - Wikipedia

    en.wikipedia.org/wiki/Railway_coupling_by_country

    The railcar couplers or couplings listed, described, and depicted below are used worldwide on legacy and modern railways. Compatible and similar designs are frequently referred to using widely differing make, brand, regional or nick names, which can make describing standard or typical designs confusing.

  6. Buffers and chain coupler - Wikipedia

    en.wikipedia.org/wiki/Buffers_and_chain_coupler

    Narrow gauge flat wagons, 750 mm (2 ft 5 + 1 ⁄ 2 in).Note the single buffer with a hook on the right side and a chain on the other. On some narrow-gauge lines in Europe, and on the Paris Metro, a simplified version of the loose-coupler is used, consisting of a single central buffer with a chain underneath.

  7. Dellner - Wikipedia

    en.wikipedia.org/wiki/Dellner

    To this end, all 400,000–450,000 freight wagons in Europe are to be equipped with fully automatic couplers in the coming years. [ 26 ] As part of that program, Dellner developed a digital automatic coupler in accordance with the DAC-4 standard, as well as a hybrid coupler for locomotives that can be used to simply convert old freight train ...

  8. Dual coupling - Wikipedia

    en.wikipedia.org/wiki/Dual_coupling

    The dual couplers are mounted to a pivot, allowing both to swing. Different types of railroad rolling stock have different couplers depending on the purpose and type of equipment being used and its intended destination. European rolling stock tend to use buffers and chain couplers while American rolling stock uses a Janney coupler or "knuckle ...

  9. Glossary of rail transport terms - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_rail_transport...

    Rail transport terms are a form of technical terminology applied to railways. Although many terms are uniform across different nations and companies, they are by no means universal, with differences often originating from parallel development of rail transport systems in different parts of the world, and in the national origins of the engineers and managers who built the inaugural rail ...
