Target class: electric multiple-unit coupler system
Context triple: [Westinghouse H2C, instanceOf, electric multiple-unit coupler system]
  • A. railway coupling system chosen
    A railway coupling system is a mechanical assembly that connects railway vehicles together, transmitting forces for traction and braking while maintaining alignment and safe separation between cars.
  • B. automatic coupler
    An automatic coupler is a self-acting mechanical device used to connect and disconnect railway vehicles (or similar rolling stock) without manual intervention, ensuring secure, rapid, and standardized coupling.
  • C. diesel-electric multiple unit family
    A diesel-electric multiple unit family is a group of closely related self-propelled rail vehicles that use onboard diesel engines to generate electricity for traction motors, sharing common design, components, and performance characteristics.
  • D. third rail electrification system
    A third rail electrification system is a method of providing electric power to trains via an additional rail mounted alongside or between the running rails, from which current is collected by contact shoes on the train.
  • E. electrified railway
    An electrified railway is a rail transport system in which trains receive power from external electrical sources, such as overhead lines or third rails, instead of relying on onboard fuel.
  • F. None of above.
