That was me. That's kinda my back garden (where we build things for testing then knock them down when we're done). It's noisy when we're trying to work stuff out. There's plenty of open space on the map, does it have to be in my back garden?
It's just a simple thing that opens gates letting water out in a wave-ish sequence. It's just a cart going back and forth on a track pushing buttons which temporarily close gates to cause the effect :) simple stuffs
Say I wanted to move about 10 chests full of my stuff really really far. Can you make a train like thing to do that or do you have to keep walking back and forth?
A railway would be worth it if you want a more permanent route to go back and forth on, but if you only want to take everything one way once then it would probably be easier to just carry it.
You could also fashion one of these monsters and put all the chests on top of it:
Although I lost a bunch of (unwanted) cobble in a storage cart recently - possibly related to a known bug in 1.7+ - so I'm not sure I'd be inclined to trust one with anything valuable.
What I'd probably do is create ten chests at spawn, then go to the old place, use /sethome then /spawn and /home to retrieve all the bits you want, then travel to the new place, /sethome again and grab all the bits.
