I have always wondered, why Lionel has never re-issued the Life Savers tank car.
Jim, it was reissued, but as a TTOS Cal Stewart meet car, in 2007. An earlier re-issue was cataloged in 2001 Vol. 1 as no. 19629, but that car was cancelled, for some reason. Here's a little discussion on the two lifesavers cars that have been produced, that I put in a thread back in 2015:
There have been two versions of this car made by Lionel - the no. 9278 from 1978, and the no. 52476, a special issue done for the Cal-Stewart train show in 2007. They are slightly different. I've attached some photos of the cars to show the differences.
The later 52476 added die cast sprung trucks, whereas the 9278 has plastic trucks (although die cast trucks can be added), and the 52476 has some added rivet detail near the end caps (Lionel changed the mold prior to this). Also, the logo and other decoration are somewhat different (the 52476 is the one with the blue background behind the Lifesavers lettering, and there are other differences as well).
In addition, the colored striping decoration is painted on with the 52476, and on the 9278 it is a separately applied covering put on with some kind of adhesive, presumably (paint processes back then were not available as they are today to do applications like this, at least at reasonable cost). Finally, the colored portions of the 52476 have a flat finish, whereas the 9278 has a shinier finish.
My personal preference is the earlier 9278 car, primarily because (at least to me) the shinier finish is nicer looking. One of the main challenges in finding the 9278 is getting one that has the chrome finish in nice shape. Sometimes, if they have not been carefully handled, the chrome finish can deteriorate and get dull (they are, after all, 36+ years old at this point).
