Are you tired of those chests, just like everyone has, standing on the floor?
You should download this.
Press a button and the chest will come to you, press another button and the chest will return.
This design is made with 8 chests.
Hope you enjoy it!!

I'm going to compare this design with my second design so you can choose wich you wanna download.

design #1
you exactly know what cart is coming to you

works like: every car has his own storage room, when you tell him to come, you can unload it and when you say it should go back you should say to what storage room and it will be stored at exactly the same place as it came from.

design #2
you can unload two carts at the same time
less buttons

works like: you tell a storage room to send its cart. the cart comes, if unload place #1 is occupied it goes to the second. when you say rail #1 or #2 should send its cart back, the car will be send to the first free spot. so it won't be stored always on the same spot.
