@tuddly:
Go Download a Program called Route Control. That will analyze all your Activities, Consists, and Rolling stock, and tell you exactly whats missing, and where its missing.
Next:
The LV RS-11's Are freeware from one of the payware companys. Think it was the same one that did the Empire State Express (Can't remember the name of that specific company).
The ATSF F-Units are Freeware from 3dTrains (Literally just go their webiste, go to Downloads, and pick the corresponding F-unit) Here:

After doing some research on the RS11's, whatever company made them seems to have allowed Columbus Locomotive Works to host the file, but regardless they can be found here:

As per all CLW DLs, you will have to register to their site to DL anything, but thats all you have to do.
Ive never heard of FFW, so can't help ya there. But Route Control will probably tell you exactly what its looking for....
@Kelticsylk:
Think you got any drawings of those Tender booster's either? They were pretty prolific on certain roads and in certain places on most roads (Usually Tenders for Yard Goats and such), but I have yet to see a single MSTS model equipped with one..... Id still love to see an IHB U-3a with Tender Booster in the sim, lol. N&W even experimentally outfitted a Y-6b with not one set, but two! lol. Even had the counterweights painted black and Yellow checkers, lol.
