What affects subway car weight

  • Body material. Aluminum cars are lighter than older stainless-steel or carbon-steel designs.
  • Car length. Longer cars and those with more seating weigh more.
  • Empty versus loaded. A crush-loaded car of standing passengers can weigh several tons more than empty.
  • Equipment. Motors, brakes, and air conditioning add to the empty weight.
  • Powered versus trailer cars. Motorized cars carry traction equipment and weigh more than unpowered trailers.
  • System design. Different transit systems specify different car sizes and standards.
