Tank cars only for certain product?

Here’s a shot of it taken in 2002 and posted by Stan Jackowski on Webshots:

Thanks for the photograph. It looks like the tankcar does not have a refrigeration unit. It appears to be a tank version of an RB.

I also noticed that Tropicana appears to lease at least one tankcar.

That residue caused a change in placarding some time back. At one time, once a tank was unloaded the placard was removed, even though there could be residue left in the tank. Now, unless the tank has been properly cleaned it still carries the placard.
