Got a link to the video about this? I love these older locomotives, but being conventional really disappoints me. If I can convert it to command, probably DCC, then I may go ahead and get it. The recent brass-hybrid 4-4-0's are wonderful. If this is along the same detail and quality, I may get one. I was hoping to run it with the 4-4-0's as a lashup, not happening now.
Be aware this is a recap of the entire catalog so you'll have to fast forward to the John Bull pages. They don't go into lots of detail but do discuss some of the features.
