Atlas is really in no position to be offering anything new, especially locomotives, until they start delivering on products that are literally years behind schedule. According to their website, a lot of locomotives are supposed to be delivered before the end of the year, Master Line F3's, F7's, GP7's MP15DC's, Dash 8-40B's and BW's, SW's not to mention Trainman Dash 8-40CW's, RS3's and RSD7-15's.
That's 10 engines by my count and I don't think even the most optimistic of Atlas supporters believe that half of those models will be delivered in 2016.
