Well I sure wouldn't say it is the "PREFERRED" track, but it is the absolute minimum for those cars. I run my set on 072 without issue using the factory 3 rail couplers. I converted my Daylight cars to Kadee and had a lot of issues requiring moving the couplers outward and even using the long shank Kadee 746 on several of them.
072 is the minimum....GO BIGGER and give up a little straight track on each end! You won't regret that choice!
