Hi
Dispatcher runs trains automatically or with manual drivers need only the head of the train detectable and a length for the train.
After the head leaves a block it shows that the block is unoccupied but allocated (so it cannot be allocated to another train) until the calculated end of the train exits the block.
It uses pessamistic assumptions about the position of the head in an occupied block.
You can also use Head and tail detection so a single car detected car at the rear is required. Lighted caboose , track powered FRED.
The major down side of head only is the failure to detect broken trains, so I would never use them for an exhibition piece.
