Hey there!

This is an modified version of my train station, especially for servers with many destinations:

Function:

You can select a destination you want to see without the need of
having a ton of different train stations, you only need 1!

The double-Dispenser-system is a foolproof system which selects the carts intelligently. Normally a cart from the first Dispenser is selected but if the first Dispenser is empty a cart from the second Dispenser is taken. If you fill up the Dispenser, the first Dispenser is filled, if it's full, the second Dispenser will be filled up. If the second dispenser is also full, the redundant minecarts are destroyed by lava.
Maybe I'll upload a seperate editable "as-many-Dispenser-as-you-want"-system later ;)

There can be added aditional tracks by editing; as many as you want!
But you have to take care of the remaining system (the blue wool below the station).
Working in Minecraft1.2.5
IMPORTANT: This is not without bugs, you can still overload the cart detectors or press two buttons so fast that 2 tracks are set

Have fun by downloading the schematic and subscribe to not miss an update!
