Stirling engine. A model of a Stirling engine showing its simplicity. Unlike the steam engine or internal combustion engine, it has no valves or timing train. The heat source (not shown) would be placed under the brass cylinder. A Stirling engine is a heat engine that is operated by the cyclic expansion and contraction of air or other gas (the ...
The cooling grill for the brake grid resistors is at the top center of the locomotive. Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed "rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and ...
The gyro monorail, gyroscopic monorail, gyro-stabilized monorail, or gyrocar are terms for a single rail land vehicle that uses the gyroscopic action of a spinning wheel to overcome the inherent instability of balancing on top of a single rail. The monorail is associated with the names Louis Brennan, August Scherl and Pyotr Shilovsky, who each ...
A railway air brake is a railway brake power braking system with compressed air as the operating medium. [1] Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869. [2] The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's ...
This cable is used to supply power to the electronic components installed on the cars. The cable also doubles as a communication medium that allows the locomotive to send commands to, and receive feedback from, the cars along the length of the train. ECP provides many benefits over the traditional braking system.
The Mod II project replaced the normal spark-ignition engine in a 1985 4-door Chevrolet Celebrity notchback. In the 1986 MOD II Design Report (Appendix A) the results showed that highway gas mileage was increased from 40 to 58 mpg ‑US (5.9 to 4.1 L/100 km; 48 to 70 mpg ‑imp ) and achieved an urban range of 26 to 33 mpg ‑US (9.0–7.1 L ...
e. A bogie (/ ˈboʊɡi / BOH-ghee) (or truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly ...
An overhead line consists of one or more wires (or rails, particularly in tunnels) situated over rail tracks, raised to a high electrical potential by connection to feeder stations at regularly spaced intervals along the track. The feeder stations are usually fed from a high-voltage electrical grid.
