Inspired by TIAS, I present to you NATS. This set intends to include a whole lot of trains from the Nagoya Metro Area, which encompasses Aichi prefecture, Mie prefecture and Gifu prefecture. Like TIAS, the trains in NATS have a set length. So far 11 operators have been finished.
Aichi Rapid Transit/Linimo will not be included as it is a part of RIMS, which can be balanced against NATS, TIAS and the Japan set using the parameters. Trains other than the Linimo can also be disabled.

License: Contributer info:
This set will be huge when finished; it will have almost 200 trains. To finish this in any reasonable timescale, your help would be greatly appreciated. I'm about 20% the way through.
I have a tracking table where you can see what has yet to be done, and what has already been done, and by who, so you won't have to do work that has already been done.
