I have one and it is a nice representation of Lionel's early attempt at sound.
Nice looking set as well.
HOWEVER..........take the tender apart before use and make sure that the foam between the electronic board and the tender metal base has not disintegrated.
Mine had.........just use something new (sticky back foam) to replace the old stuff.
You will short out the board if it comes in contact with the metal base of the tender.
I had to use Q tips and alcohol to clean the old stuff up.
