VERY  NICE  Bob

How does this work and stay with the car ?

There’s a fan in the car that pushes it up. I’m thinking that the size of the turbulence has a larger diameter than the ball so it creates a kind of cradle that the ball doesn’t break through. If there are any engineers out there that can provide a better answer; I’d like to hear it.

You nailed it Bob. The air column holds the ball inside. It is a neat car.

Don't necessarily need the engineers Bob.......this thing is fun to watch.

Bernoulli principle. The moving air column generated by the fan is at a lower pressure than the still air around it. As the ball moves out of the column, the higher air pressure outside of it pushes it back in. It's why airplanes fly. At constant airspeed, air moves faster across the curved top surface of the wing than the flat bottom surface, resulting in lower pressure above the the wing than below it, generating lift. Regardless, I've got to have one of these now. Do they make it in 3-rail?

🥺 I should have remembered that from my aviation familiarization course in the NAVY.

Couple PW Lionel early-Cupola Type 2457 from 45-47 had a nice toolbox, generator and steps, the other 2472 from 46-47 shows the cutbacks on the product also noted is the brake wheels and smokestack on the 2457. To bad Lionel made changes on so many of their products.  They also made a nice looking brown 2457 with white lettering and a 4457 red/white 46,47 in the Electronic Set, These all came from left over prewar era. God Speed All!

@Sitka - Great cabooses...I also have several of the early post war sheet metal.  Way too soon ( like 1947 ) Lionel moved to introduce the "plastic" SP type caboose and the sheet metal ones were too soon gone.  One curiosity though, although the 2472 clearly had cutbacks on "add on" features it did have 2 automatic couplers whereas the more featured 2457 only had a coupler on one end.  Interesting choices by Lionel.

Best wishes

Thanks Don just picked up a 225E with diecast tender after looking at it, looks like Lionel changed some tooling and made a K4 out of it will post the two for how they look, the 225e has a great looking boiler front. HAGD hope all is well with the wife God Speed! Mark

Nicely done interesting info on the changes made to the caboose Mark.          Was there a price drop in the newer version or just cost cutting ?    Seems like the newer version could have had less obvious cuts

Most likely cost cutting, bought a 225E prewar and broke it down for degreasing what a difference in some of the parts the trailing truck has little nuts to hold the bearing cap in place, The boiler front opens like the berk pretty sharp. Got some weight to it also. God Speed Dallas!
