A grid resistor assembly includes a plurality of flat grid resistor elements. Each element includes at least one open-ended loop having side portions and a tip end portion connected together through intervening strip portions of narrower width than the side portions to improve current carrying capacity and to provide for more even heating and heat dissipation. An assembly of such elements is particularly used as a resistor box in an electric, motor-driven, transit vehicle, such as a subway car, and is provided in a predetermined space envelope to perform predetermined electrical parameters.
