I remember hearing this song in the credits of The History of Lionel Trains by TM Book & Videos. I was around twelve years old at the time. I'm glad I finally found this song again
My grandfather's mobile home park was just behind the right hand side of the shot behind the station. Mr. Cash and his wife lived there for a couple of years before he got to making money with his music. Just a few years after this commercial was aired, Willie Nelson bought a old tavern that was just to the left of this shot.
Even if people today see the mighty sound of steam as just plain annoying remember, this was the early 70s. This was considered revolutionary for model train sounds.
Do you have a complete copy of this commercial? It's the only copy of this version I've ever seen, and it cuts off too quickly at the end. Would love to see the rest!
