Thanks for the model number.
Rio Grande. The Action Road - Focus 1977-1983
It will be easiest to operate them together if they have decoders that offer the same motor control. Soundtraxx has motor only decoders that match the Tsunami 2, and even a 21 pin model. MC1H104P21 is the 21 pin motor only decoder.

I've purchased a Genesis F9AB set with DCC/Sound (they come with Tsunami 2), and a companion DCC ready F9B.
Would it be best to buy a same brand DCC nonsound decoder to go in the B unit? It has a 21-pin NEM DCC plug. Does Soundtrax make a 12-in non-sound DCC decoder and if so, what is the part number. Or does it matter?
