One other thing. That set engine is not a "full" sized Rail, King. It is what they called a "Bantam" sized. Probably actually smaller than the original Lionel S2. You can see the boiler section is no longer than the RK box car. When the Rail King PRR S2 came out it was about 26 or so inches long boiler+tender.
The other thing the sound file was not of a Turbine's "whoosh." It is a "chuff." And I guess for a kid that may make sense.
