RailDest

RailDest is a plugin that enhances rail mechanics, allowing for automated routing
across rail lines according to a specified destination. The plugin uses the
redstone mechanics of a T-junction that follows the southeast rule and interacts
with detector rails.

Usage

/dest place where place is the place where you want to go. You can also
chain
destinations /dest place1 place2 etc. this can be useful for taking a route
via specific junctions, RailDest will route players towards signs that contain
either place1 or place2.

Junction setup

A sign with the destination name on it must be placed over a detector rail
like in the image shown below.
The sign's first line must be [destination], then the other three lines can be
destination names. You may also
use [!destination], which will activate the rail if a player's destination is
not on the signs.

If the signal needs to be inverted, an invertor could be used as such shown
below:
