Re: What exactly IS SMEE?

Posted by randyo on Wed Oct 13 16:34:44 2021, in response to Re: What exactly IS SMEE?, posted by Lou from Brooklyn on Wed Oct 13 11:41:57 2021.

SMEE equipment has both an A and an R wire. The A wire provides trainline application and the R wire provides trainline release. On older equipment the R wire and R magnet controlled by it are misnamed since the R magnets are for retaining air in the brake cylinders till deenergized by placing the brake valve in the release position. On SMEE equipment, the R wire and R magnet are energized to effect trainline release of the brakes.
