Trains are the best form of public transport, and bringing them to Minetest is brilliant. This mod offers realistic railways, with high-level automation APIs and cargo possibilities.
All the other transport mods have nothin on Advtrains, and can only offer little of what Advtrains offers.
I have used it to connect my server. I can sit and watch trains pass at high speed or board a train and get somewhere in style. Whilst teleportation is more convinient, it does not help with cargo transport, one thing that Advtrains handles amazingly.
Overall, this mod is very good for making good transport systems whilst keeping realisim high on the agenda.
