DCC = OK, Sound = challenge

Dear John,

Assuming it's a Atlas RS1 or RS3, and you're only looking to add DCC control, it looks like TCS have you covered with their "CN" series decoders

http://www.tcsdcc.com/public_html/Customer_Content/Technical_Info/Tech_Manuals/TCS_Book_of_Classic_N_Installations.pdf

As for adding sound, that's going to get more tricky! The sheer narrow/small cross-section hood of the RS shell doesn't look to allow a lot of room, unless you start removing significant ammounts of frame/weight and/or possibly a gear-tower. (Wouldn't be the first time someone has forgone powering one truck to shoehorn sound into a loco, even in HO or even O-narrow scales!).

A Zimo or CT Electronik "sugar cube" speaker would likely be the best bet as far as a speaker-that-would-fit would go, but finding a suitable sound decoder is the big showstopper...

Best of luck!

Happy Modelling,

Thanks again prof. I model

Thanks again prof. I model the 60s so I want to stay in that era. Also rural n. michigan (huron shore) no passenger work to speak of. Dirty locos pulling dirty cars pulling dirty rocks. When I upgraded my old lenz set 02 I wanted to at least try sound. I bought an atlas C628 that was advertised to be dcc sound equipped ,It was not. True to form my LHS (caboose hobbies in Denver) Said I could ship it back and they would refund my $,give me store credit,or anything else I want. What I want is a Nscale loco with a sound decoder(oem or after market). I dont want a big steamer or passenger diesel,they dont fit with my fantasy rr.

again thanks

john
