A parking brake reset system for a railway vehicle, such as a transit vehicle, includes a brake operating unit fluidly connected to a main air reservoir and controlling air flow to a brake cylinder of the railway vehicle, a brake pipe, a parking brake, and a control valve in line between the brake pipe and the parking brake to establish fluid communication between the brake pipe and the parking brake. The control valve is in line between the brake operating unit and the parking brake, whereby the control valve controls air flow to the parking brake from the main air reservoir and the brake pipe. The control valve may be a double check valve or a 3-way cutout valve, as examples.
