Factorio - Artillery Train Transforms Into a Chainsaw to Defend Itself From Waves of Biters
Inspired by the one I put around my whole base for general defense, in a past video.
If you're wondering what the stuff in the top left does, it automatically disables the parking station using a circuit clock to send a signal to disable the parking station after the train stops at it, so that the train doesn't keep trying to go there and wait another 20 seconds every cycle through the train routes, so then I can have the train go infinitely between loop 1 and loop 2 stations.
