Just completed a decoder install in my Kato N scale 2-6-2 Mikado. I found the new Digitrax  DZ 126 T a great decoder for this purpose. The install in the boiler is not simple but very doable. Plenty of space can be created and wiring poses no problems. Even this tiny decoder has transpondering which I require for Surroundtraxx. Attached is a photo of the little beast. I yet have to add a vestibule all weather cab as I model Canadian Pacific. This I purchased from Miniatures by Eric. Can't wait to finish a complete detail.
