Features

• add a new combinator
• at a train station, read a signal and add filters to wagon to match the count of items
• read filter on wagon, compute missing items and write to the output of the combinator
• when a train leave the station, scan filtered inserters and remove stuck items

Usage 1: create a train payload from a set of signal

• add a tc combinator near each wagon
• in the first wagon, connect a RED wire to the input
• in the configuration of tc, select "Read red signal from input"
• add filtered inserters for loading
• for each wagon, connect the output of the tc controllers to the inserters and set the action to "set filter"

Usage 2: precise loading using LTN

• add a tc combinator near each wagon
• in the first wagon, connect a RED wire to the output of the LTN station
• in the configuration of tc, select "Read red signal from input"
• add filtered inserters for loading
• for each wagon, connect the output of the tc controllers to the inserters and set the action to "set filter"
• optionally, connect the output of the tc controllers to logistics chest and set logistic request
