I been following this with interest.. Looking at the new catalogue I have noticed a few things. So here are my thoughts.
It seems they are introducing more of the K line based cars.
I can not wonder if the GP38 will be from the K Line tooling. If the they are using the HO GP38 in the catalogue I would think this is the case.
Will the FA1s have lighted number boards and running lights?
On all the engines that will have the true blast plus will they install a volume control as they need to. I have just bought the GN GP30 and I love it. But I disconnected the sound board as I could hear the engine 2 rooms away. They could also add a capacitors so when you change direction you still have sound.
As for operating systems. I think they should just start selling O scale engines with the new remote feature but with a small hand held remote now. Otherwise they are going to be left behind quickly in market share with Lionel and we may never see any type of new operating system.. The new chuggington line would have been a good place to start.
The next thing they should do is just start wiring the motors in series from the factory. Since this is a mod most people do anyway.
As for rolling stock They need to drop the prices on the old molds and start introducing update rolling stock with more detail..
Waycars and cabooses. Since they own the molds from K line reintroducing the Cabs from that line will increase the variety of cab. but if they really want to do this. How about CB&Q/GN/DRG style cabs/waycars.
