ABSTRACT:
A resistor grid suitable for dynamic braking of diesel electric locomotives includes an upright rectangular frame with top and bottom members of insulating material and a strip of resistance material fan-folded into vertical flights between the top and bottom members. Fixtures attached to the top member suspend the fan-folded strip by its top folds and fittings affixed to the bottom member tension the fan-folded strip through its bottom folds.
