This was a premium that one could get by sending off Kellogg's cereal boxtops -- which we did. It was billed as a "Jet Drive Whistle Loco," a title that definitely overpromised.
Basically, you fit an inflated balloon over the smokestack. As it deflated, some of the air escaped through a slot on the top of the boiler, creating a train whistle. Most of the air went out an opening in the back, making the "jet drive" that pushed the engine along.
There were two things I remembered about this toy.
- It looked pretty good.
- It never worked very well.
Fast forward forty years, and I once again have the Elmar loco in my possession. After giving it a good cleaning, I gave it a try. I have two thoughts about the toy.
- It still looks pretty good.
- It still doesn't work very well.
Still, it looks pretty good sitting on my desk. Thanks, Dad!
