 - ``Wagon(ORTSBrakeCylinderSize`` -- If brake cylinder dimensions are

-- ``Wagon(ORTSBrakeCylinderTravel`` -- The length of brake cylinder extension

   when the brakes are applied. Larger travel leads to larger brake cylinder
   volume, and volume will increase as the brake cylinder pressurizes.
