After seeing a 50's era photo with a Rexall Drug Store prominently occupying a corner store in the center of the picture, I was immediately reminded of the occasional childhood dilemma of deciding whether to spend the extra penny for the "Cherry" fountain Coke... Then, I decided to do a little research to determine which, if any, drug chain purchased and replaced many of the Rexall Drug stores.
Much to my surprise, this is what I found on Wikipedia:
--------------------------
"Rexall Train
The Rexall Train of March to November 1936 toured the United States and Canada to promote Rexall drug store products, and to provide the equivalent of a national convention for local Rexall druggists without the cost of travel. Free tickets for locals to see displays of Rexall products were available at local Rexall drug stores. The 29,000 mile tour visited 47 of the 48 contiguous states (omitting Nevada) and parts of Canada. The blue-and-white train of 12 air-conditioned Pullman cars with displays in 4 cars, convention facilities in 4 cars and a dining car was hauled by a streamlined 4-8-2 Mohawk locomotive, No. 2783 from the New York Central Railroad. It was the million-dollar brainchild of Louis Liggett, who travelled in the rear observation car."

That's a sharp looking streamliner from the mid 1930's! I'll bet they served fountain Coke somewhere on the train.
