Introduction.
MineTrain allows you to make
public transit network on your server with multiples
stations on different
lines.
This plugin is
redstone-free,
config-free and
code-free, you can do all on your server with a
step-by-step user-friendly editor. It's easy for you, and for your players

.
Is it a TrainCarts replacement?
Yes and... No.
TrainCarts is a really nice plugin (the best minecart management plugin) but is it
complex and tedious to make things that are easy like a
Subway system. Also, MineTrain is sign-free and redstone-free with a user-friendly step-by-step editor making it
accessible to all. But if you want to make a complex transit system, TrainCarts will be probably better for you.
