A train-stop combinator that validates each train's dedicated buffer individually, instead of pooling all station storage together. One main unit wires to the station; empty 'buffer probe' shells each wire to a single train slot's chests. The main reads every probe's network independently and calls a train only when that slot's buffer is actually ready. Inspired by Simple Train Combinator by Odja_Anarchist.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
