This is a fully automatic minecart system that we are making using the tekkit mod pack on Oakrealm tekkit survival. I am mostly using railcraft with a bit of buildcraft and redpower mixed in.

Features:

• Two and a half (We haven't quite finished one of them) fully functioning and automatic minecart stations.
  
• Each station features an arrivals and departures area (whether they are separate or combined depends on the station).
  
• To depart all you have to do is press a button to release the cart then get in.
  
• The cart dispensers are automatically filled up by a chest underneath them.
  
• On arrival you are automatically ejected out of your cart then it continues down into an area where it is collected up and put into the chests that stock up the cart dispensers.
  
• High speed rails to get you to your destination fast!
  
• I am currently working on an automatic empty cart detector to prevent people from clogging up the rail lines. If the cart if empty it will be sent to where the arriving carts go.
