OK, I had a few minutes at work to play with my Build 50 at work. I tried to get it to the same point as I am at home, but because of the randomization I can only get close. While putting together screen shots of the starting point, I noticed Build 50 doing the siding shuffle. I have this documented with screen shots, but didn’t want to clog this thread with it. Here is a link to a PDF if wanted… http://lsc.cvsry.com/trainops/V50ScreenShots.pdf To start, I checked the industries to be sure that the sidings were not marked as a yard. Next I checked Equipment Location and everything was Off-Layout (this is a fresh start DB) Then I built my train MX10 which did a normal job of moving 4 cars from off-layout via a yard track to two industries. After terminating MX10 I again checked the Equipment Location and the cars show at the industries like they should. OK, so lets run Train ZXIC that runs from the interchange to an industry at NOOK…

Car 957 and 170 get shuffled. It looks to me like when an empty becomes a load that it goes right back to the industry demanding loads. Could it be that because I only have a small number of industries (in the case of train ZXIC, just one) and very few cars that there isn’t enough in the database for the program to process properly?
