I couldn't resist sending this picture when I saw the lineup on my layout. The Big Boy, the Mike and the Heisler. From the very large to the very small. The Big Boy and Mikado are by Marklin and the 3 truck Heisler is a Marklin converted Riverossi model. All are digital and the first 2 have full sound. In the past I worked on a tourist RR that had an actual wood burning Heisler and a Mike, so from this I can really appreciate the immense size of the Big Boy.
