A few ago I built a flatcar. http://www.largescalecentral.com/LSCForums/viewtopic.php?id=14788 Well, I decided it needed an interesting load. There is a guy on fleabay selling the ag version of the TD-24 for $29. A damaged load costs money, not makes it. So rather than just plop it on the car, I decided to see how it was supposed to be done. This is a WWII era smaller TD-18 headed for Russia.

According to text I found on RR rigging for large crawlers, there should also be four chains.
I still need to add the 2 crossed chains across the tracks.
