ABSTRACT:
The present invention discloses a hand brake mechanism having a gravity based release hold mechanism with a visual indicator to prevent unwanted application of the railcar brakes and indicate such release hold condition. The release hold mechanism comprises a gravity based member pivotally linked to a release shaft preventing reverse rotation of the release shaft causing an unintended take-up of the chain. A detent retaining device disposed within the railcar hand brake housing further provides improve reliability of the operation. The gravity based member incorporates an indicator portion having a reflective coating to indicate such release hold position of the railcar hand brake.
