Ok, as promised, here are a few pictures. First I tried to build an Astro-Train: Astro-Train I en orbite by comiquaze, on Flickr The concept worked, but it had no where enough d/v to go to Moho. So I went back to the drawing board and modified it so it could really work like a train. For that, I need to be able to ditch the main engine.

Now, I tweaked the design a little bit and I added a few Sr. docking ports and moved the standard ports around, to be able to carry a lot of stuff around.

All that will then voyage all the way to Minmus. I still need to add my Skycrane to it and to figure out a way to attach a few probes... Oh, and I still haven't figured out how to do a nice simple rover for the kerbalonauts to drive around in.
