   en.wikipedia.org/wiki/List_of_railroad_truck_parts

   An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.

3. Coil spring - Wikipedia

   en.wikipedia.org/wiki/Coil_spring

   Types of coil spring are: Tension/extension coil springs, designed to resist stretching. They usually have a hook or eye form at each end for attachment. Compression coil springs, designed to resist being compressed. A typical use for compression coil springs is in car suspension systems. Volute springs are used as heavy load compression ...

4. Buffer (rail transport) - Wikipedia

   The first ones consisted of a steel rod that carried the buffer plate at one end. The buffer rod pushed backwards on a spiral volute spring (coil spring), which was supported by a strong sheet metal cylindrical sleeve. Compressing the spring absorbed the impact. The first spring-loaded buffers were invented by John Baillie in 1846. [3]

5. Spring (device) - Wikipedia

   en.wikipedia.org/wiki/Spring_(device)

   Coil spring Also known as a helical spring. A spring (made by winding a wire around a cylinder) is of two types: Tension or extension springs are designed to become longer under load. Their turns (loops) are normally touching in the unloaded position, and they have a hook, eye or some other means of attachment at each end.

6. Clutch - Wikipedia

   en.wikipedia.org/wiki/Clutch

   The clutch consisted of a wrap-spring clutch-brake that was coupled to the rotor by one or two stages of reduction gearing. The clutch-brake locked up when rotated backwards, but also had some spring action. The inertia of the rotor going backwards engaged the clutch and wound the spring. As it unwound, it restarted the motor in the correct ...

7. Flexicoil suspension - Wikipedia

   en.wikipedia.org/wiki/Flexicoil_suspension

   Flexicoil suspension is a type of secondary suspension for railway vehicles, typically having steel coil springs between the bogies and chassis of a passenger coach, freight car, or locomotive. Suspension systems using steel springs are more common than those with air springs , as steel springs are less costly to make, relatively wear resistant ...

   Harbor Freight Tools won a declassification of the class action; that is, the court found that all the individual situations were not similar enough to be judged as a single class, and that their claims would require an individual-by-individual inquiry, so the case could not be handled on a class basis.
