I'm happier with a functional weiner, I know that for sure.
The body is 3" wide almost exactly, and around 8" long. The tail of the wiener sticks out another two inches to make the OAL around 10". Height above the track rails is exactly 5", which has been an issue with certain areas of some layouts.
The largest board is the sound board, it's in the bottom rear and it's about 2 3/4" long, just fits as you can see. The other boards easily fit inside the wiener.
