That wagon looks to have 2 ways to carry the tracks. I don't know why they would have it with the tracks standing on end way because it looks like the 2 yellow pieces will be easily lost by children. The flat way to carry them looks to be the better way.
Personally I think the better way was from the original Track Repair Wagon in the 'Protect The Rails, Track Maintenance Set' because it needed only one larger piece to hold the tracks on. I don't understand why they didn't just re-release that one as a single. Shown in this video starting at the 10:55 minute mark. https://www.youtube.com/watch?v=v9rIUgYtdOo
