To start, I cannot afford Premier, so I only buy Rail King and Rugged Rails trains.
Also to start, what our hobby does not need are more GG1s, J Class Hudsons, J & GS Class Northerns, Big Boys, Challengers and especially engines with Belpaire fireboxes.
My rail King / Rugged Rails 2017 wish list includes the following, all with the latest DCS ProtoSound system:
> Iconic New York Central S Class electric. I know Lionel did this locomotive, but I want an affordable MTH product with DCS;
> Osgood Bradley open trolley car like those the Connecticut Company ran for the Yale Bowls. It would not bother me if the middle of some bench seats had to be notched-out for a motor and electronics;
> BRT / BMT train open platform cars like those that ran on the Myrtle Avenue El in Brooklyn;
> 027 size 1st generation diesels such as the Baldwin RF-16 Sharks and ALCO FAs with freight / passenger sounds;
> Steeple cab electric locomotive;
> 027 New York Central / B&M / CNJ 4-6-4T commuter tank engine;
> Less common streamline steam engines like this beauty:
