Visitors to my site often come through with information I am seeking and this is one such case.
I have been looking for the correct tractor for this set for years. I have bought several different variations, all wrong. Now I know what to look for!
This set, which I thought was Joy Line is actually a Marx set. I have learned that this is one of those toys Girard produced under contract for Louie.







I knew these cars were not for use on track. Many of the early Joy Line Trains will not run on track.
