I have an Atlas SD-35 (cat. # 6810-1) that I purchased in 2000 (it was released in 2000 and was bought new ) and it has TMCC and Railsounds 4.0. Everything on this engine is factory and no modifications have ever been made. I would like to upgrade to cruise if possible using one of ERR's upgrades. I need to know if I can buy just the Cruise Commander "M", or if I need the full Cruise Commander which as I understand replaces the existing motherboard and is a more extensive upgrade than the CC "M". My Atlas does have the Lionel boards including a Lionel motherboard and a R2LC07 radio board. However, I was told by a Lionel service technician that an ERR upgrade may not work and he recommended that I call Atlas which I did yesterday. Atlas said the Cruise Commander "M" should work, but that I would have to buy another radio board as the R2LC07 is not compatible. Atlas said a R2LC-C08 or a R4LC should work. If that is the case, then Lionel has the following available on their webiste:
| 691R2LCC08 | R2LC / RADIO RECEIVER (C08 CODE) |
I have also attached some pics of the motherboard on my Atlas as well as the Railsounds board version as I was told that some Railsounds boards are not compatible with the newer ERR upgrades. So there are a few variables that may or may not allow me to upgrade to cruise by installing just the Cruise Commander "M". I would not want to invest the money that it would take if I had to upgrade almost everything to get cruise.
Any experience upgrading a 20 year old Atlas diesel like mine to cruise?
Thanks in advance!
