I assume that setup probably saved a few relays or logic checks.

The intermediates “float” when no route is lined up. They don’t however clear up directly behind a train for the reverse direction the way block signals do. Instead, they clear up once the train completely passes the next signal.<br /><br />I’m guessing it may be a tweak to avoid implying authority for a reverse move. Unfortunately, I do not have any information on the signaling technology installed. <br /><br />Eric<br />redoveryellow.com<br />Anonymoushttps://www.blogger.com/profile/14872748692037505945noreply@blogger.com
