Head Only.
This means that only the head of the train can be detected.
You must specify a train length and all your blocks must have their lengths specified.
It works best if you use speed profiles.
When the head of train leaves a block, that block will not be released until the calculated position of the tail is beyond it. The section will not show occupied, but it will continue to show allocated during this period.
?
The very serious disadvantages are that if a train breaks in two another train? can crash into the tail, if the head stutters, stalls or plays silly Bs then the position of the tail is nolonger reliable and another crash happens. It cannot be used for forth and back running. I recommend the use of a remotely controlled power outlet for the command station and boosters, no keep alives, no analog, no resume on track power on, and that a twenty year old in top mental and physical condition keeps the remote control in their hand.?

Ghosts.
Ghost blocks were designed for those short pieces of track needed to join 2 switchs and keep the block routing table / SML straight. The fact they appear to work for switchs was pure dumb luck.? Do not use with head only. The train must always be in a detected block and not disappear into a ghost.
