in the direwolf20 FTB pack i have built a railcraft system to automatacly sort villagers.
first the minecart passes over an embarking track and picks up a villager it then continues untill it reaches a villager detector if the villager in the cart matches the one in the detector it activates a switch moter which causes the cart to turn and to travel over a disposal track where it drops the villager off, it is then sent back to pick up another villager. if the villager is not the same as the one in the detector it continues to the next one untill it finds the appropriate one.
the next part of this system is the villager selector which lets the player select what type of villager he or she would like to trade with. the player flicks the lever that represents the villager they would like to trade with then presses a button to send a minecart to collect the villager of their choice. this works using red power cable. each villager type has its own colour of cable that goes into bundled cable and comes out at a switch motor. the cart goes to a villager holding cell containing the type of villager that the player has selected picks up the villager using an embarking track then returns to the player with the villager.
