Smart Carts is a new plugin like minecart mania but made for all 1.8.x versions and more!

Release the power of obsidian block by using it to control your carts using signs !

With this plugin you can change the behaviour of minecarts, create smart or redstone-controlled stations and intersections, and even use signs to go even deeper in the behaviour customization.

As I use this plugin on my own server, you can be sure that it will stay updated and that all issues will be addressed ;-)

I published a v2.0 development snapshot, here is how to use it:https://github.com/cambierr/SmartCarts/wiki

Existing features:

Change maximum minecart speed
Change the minecart speed
Eject passenger (to specified coords)
Load nearest player
Killer minecart (on collide)
Completely stop minecart
Minecart spawner/despawner block
Station blocks (stop cart and release it on redstone powered and/or after a certain time and/or when a player enters it)
Auto-check for updates (this can be disabled in config file ;) )

Upcoming features:

Killer minecart (in radius)
Change minecart properties (like max speed, killer functions, ...) via blocks + signs
Intersection blocks
Disable passenger cart control (speed up/down manually)
Advanced detectors (mob type, mob age, player inventory, cart type, ...)

By the way, project is open-source under MIT so feel free to clone, collaborate (even for very basic changes like spelling), and send pull requests to make people even more happy with Smart Carts :)

If you, for any reason, need fast response, I'm never far from my twitter
