How many Chessie units are you ordering? You said one up above but you could probably use 3 to 4...
I think he wants a few Wheeling & Lake Erie units, as the rest of you should. At least 18 of you since I have the first 2 reserved...
Keystoned Ed posted:Cannap - I think you will find a big difference between the older model QSI decoder used in AtlasO diesels and the later design QSI Titan loaded with a Q3 sound set. You will also experience better starting / low speed performance than the Atlas model due to Sunset's single motor drive setup. For owners of earlier 2 rail Sunset 3rd Rail diesels you may want to consider investing in a QSI Programmer ( possibly with friends in your area) so you can replace the Q2 sound set with a Q3 one (available on the QSI Solutions web site). I did that for my E7's and was please with the improved sound and operation.
These 4 SD40's are preordered and are due 2nd quarter of 2017 so they'll probably come with the latest QSI soundsets. I'm planning on getting a programmer anyway.
I won't attempt to mix a China drive with a canon motor so the Atlas and Sunset models will not run together.
