Tomy Plarail C62 variations?

[ripley802]

So in my hunt for the C62-2 Tandem Sound variation “Silver swallow” I believe, it seems there are some others out there too.

Do any of he others have sound? Maybe they reused the bodies for some of the models possibly? Seems like some have what look to be speaker holes in the tender but have no sound?

Here is what I know of so far:

- C62 1 & C62 2 “Silver Swallow” black set
- Same as above only the Rare “Clear” version that recently came up in the auctions
- C62 (not sure on the number, maybe 18) but comes in a 3 pack with a green train and a blue/white train
- C62 3

Any others? What features? Sound, lights, etc...
