Hello, when using this mod with Industrial Revolution 2, FARL and the FARL module are both missing from the the research tree. I believe this is because IR2 removes the Rail Signals tech and replaces it with Automated rail transportation tech. Thanks.

This issue also is affecting me

Found a work-around.

Note: Disables achievements

Put the following in console:
/c game.player.force.recipes["farl"].enabled = true
/c game.player.force.recipes["farl-roboport"].enabled = true

Same issue with IR3 I suspect. Can't find FARL module anywhere....
