That is what I had done cause I am looking at getting one of the new 4-6-2 and since I would want it with a Soundtraxx Tsunami2 decoder I had been curious as to whether or not it was the same tender chassis as the 2-8-2 and how to get a spare tender chassis so I wouldn't have to buy a complete 2-8-2 for a tender swap so I coupld fit the 4-6-2 with a Tsunami2 decoder.
