Unusual Cue from 1992 Showcase

I know this is a definite longshot, but I'm curious about an unusual cue played during a 1992 TPIR Train Depot showcase.

Here's the episode from Dec. 7, 1992:

The cue starts at 37:53. It's a definite departure from the old "Chattanooga Choo Choo" cue they played in the 1970s, but I don't recall this cue being used more than a handful of times. I like the cue a lot even if it seems a bit strange for that particular use.

Anyone know where it came from?

It sounds very stock music-like. Might be something from either the Killer Tracks or DeWolfe production music libraries.
I tried searching for tracks based on one particular composer of a similar style I'm familiar with but no luck.

I remember this cue. The middle section sounds the most familar, and sounds like a section from another cue they used for trips.
