The current white Tropicana car shown is actually 64' scale length with the platforms, as the photo shows, the refrigeration unit is now on one of the front ends making it easy for the railcar team to service the unit.
The Orange paint scheme is a 57' length mechanical reefer with refrigeration unit on the bottom of the reefer box. Weaver's 57' mechanical reefer is the closest to that era boxcar. The MTH model you show is non refrigerated plug door boxcar in terms of Tropicana use. It, to my knowledge, was only painted the dark green that the Atlas O model was released as.
The paint scheme on the MTH model you show is a bit of a mix, the logo with Tropic-"anna" in her hula skirt (so named as a niece of the founder of Tropicana at the original plant in Bradenton FL in the 1950's) was a partially correct logo but used on the previous to the all orange boxcar paint scheme which was.......... back to white!
Weaver does a good job of capturing all the paint schemes for the most part. They released the current white paint scheme in their 57' reefer as CSXT which is partially correct, but only a few really run the rails that way. For now anyway.
Not sure if you were looking for more info but thought I would share, I worked at the plant in Bradenton for quite some time..............
