I am familiar with standard solenoid switch machines (like Atlas) and stall-motor machines (like Tortoise) and have used both.  The RailCrew machine appears to be a solenoid device but the documentation shows what looks like a dpdt toggle switch that does not use all of the contacts.  I am missing something here...

I want to thank everyone who has shared their experiences with 3D printing. After carefully reading everyone’s posts, I have jumped into the deep end with both feet. I now keep asking myself why I waited so long! I have made some simple items like barrels, pallets, roof fans and now I am creating some people. Yes, my head is spinning with the possibilities.

Looking for the name and description of that 'wheeled type' tool that would mark the centerlines of track onto the subroadbed of plywood thru the paper pattern lying on the plywood.

I have most of my track plans drawn out full scale onto brown 'construction paper', and now I wish to start laying track onto the plywood deck, but can't leave the paper pattern under the track.

My trusty Truck tuner has gone MIA so I ordered another that came in today.  It looks different than the old one but as long as it works right.  It was tight getting it in there so I thought the truck really needed to be turned.  Went to do the other half of the same truck and SNAP went the truck.  I knew it was tight but the truck shouldn't have broke.  Grabbed another one of a different brand and the exact same thing happened!   I put the tuner next to a wheel set and the tuner is noticeably  longer.  So, does this look right?
