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.
