Crawlers are delivered

I finally for the blocking etc. done for the crawlers. Tried something different with these.  The crawlers are removable so once I deliver the car to a dock, I can take off the crawlers and on the next operation day pick up the empty flat car and return it to Denver.  Then the car goes into the case and I can put the crawlers back on it for the next delivery. 

The blocking ended up a little fiddlier because on my first test run, both crawlers fell off.  Bad for business. They are very light 3D prints so I needed some more hold-downs. Now they stay but are removable.
