I have an issue I can't track down and think it might have something to do with ghost block. It's repeatable. Every car in both trains is detectable. (I use BDL716 and tests show it very sensitive and reliable.)
Waits about half a block west of the turnout for it to close before proceeding thru eastbound
Dispatcher throws turnout as soon as preceding block clears and before last passenger car clears causing short
Dispatcher allocated the turnout and threw it while a car was on the turnout.
It shouldn't matter for this but my blocks are all longer than the train and have accurate dimensions as well as the train has accurate dimensions. I also check full train in autotrain. I don't believe an intermittent bounce would matter since the BDL716 has debounce and I've never seen the test LEDs on BDL flicker.
Here's a log snippet of the action.
