This is quite strange. I just ran the scenarios through RW_Tools again and I'm fairly sure that I didn't forget to list any rolling stock items in the readme. There certainly isn't anything from Horseshoe curve in these scenarios, and the route is 100% freeware assets anyway.
Did you download the scenarios from the file library here (TS2012 section), or the recently uploaded files at trainsim.com, or my website? They are all identical. -- I'm not sure, however, if there may be some other outdated versions of this scenario still floating around on other places which I didn't upload myself. But if you got it from one of the three sources I just mentioned everything should work (in theory).
If the error persists, could you maybe post the exact wording of the error message? The missing "double door boxcar" is also weird, I only used the default 50' youngstown door PS-1 box from my basic kit, or the cars from the PC pack in the payware version. There shouldn't be any double door boxcars in the scenario.
