Hello i need plugin for big rail system
Concept 
(yes , i see this in very old private server)
- Block (then id configured by config) placed under a railway arrow (or any track for rail stations) and get id by command or automate (simple /id 1234)
- Rail station is create by command on this block (/station 1234 name)
- And command specifies what blocks in what way (simple /id 1234 north 1235 , /id 1235 south 1234)
- Player enter command "/metro name " and run minecart , plugin is make path by this data and rotate minecart in railway arrow to route to station (for big system need cache routes)
- Minecart shop (or free distributor) to put minecart to rail , and return minecart to shop then minecrat is free (chest and sign for price and amount minecart)
- Increase in speed minecart started by command /metro (for long distance very need)
And yes this need in server side plugin .
Sorry english is not my native lang
