I fixed the droptower you now can add a tag to a train that toggle a tcc power channel via the tag "power,name" this would power /tcc power name pulse in order to execute something when a train gets dispatched from the coaster sign i added. also everything should work up to 1.20.1
This Update features the "coaster" sign place it down to add a station.
It features autmatic coaster restraints animation, as well as an integrated countdown.
