From my understanding my options are Atlas, M.T.H. or Sunset Models. I like the looks of the Sunset models, (CNW SD40-2) but they are a little more money and seem to need larger radiuses from what I could read on their website. I'm not sure but I think I only need a DCC system as the M.T.H locos will run on DCC? The only thing that bugs me about the M.T,H diesels is how high the body looks above the trucks at least in the photos. I only have pictures to look at so I'm hoping you fellows can shed some light on what you like about the locos and do not like. Also, I am used to the cruise control feature and worry that with the Atlas and Sunset locos I may not get as good of slow speed operation.
There are lots and lots of different O scale models. You can find all sorts of things at O scale shows on the big ugly auction site. Of course all the older brass stuff and other stuff requires you to install you own electronics unless you stick with straight DC, As you say, MTH stuff generally sits too high on the trucks. You can verify this by looking at simple equipment diagrams, or scale drawings of the prototype. I personally like single motor drives. I have yet to see a dual motor one that is quite as smooth in operation - my experience and opinion. Given that I consider the Atlas SW9 a very good model both for detail and operation. As you say the Sunset models are better detailed. In that space, I would shy away from 6 axle locos. they do generally require broader curves and the size is more overpowering on a smaller layout. That said, I have a pair of Sunset E7s that easily track around 48 inch radius curves.
As for control, I think DCC is more practical. We just saw that MTH is shutting down and the future of DCS is in question. With only one supplier, it leaves you very vulnerable if they go out totally. On the other hand DCC is supported by at least a half dozen suppliers. Most of your cost for DCC will be in Decoders if you have any number of locos. They car compatilbe with any DCC system. Throttles are not interchangable.
Lastly in the spirit of train kinship I want to answer these questions and make a video so other guys like me may consider the 2 rail rout. The size and detailing of scenery is so appealing in O it is what keeps me dreaming about it. Yes there are limitations in two rail O. However, I'm sure there are plenty of other people out there like me who lack information/experience in two rail O and would go for it if examples are there.
What are the pros and cons of different manufactures' engines
Two motor locos do not run as smoothly in my opinion. MTH models generally sit too high. Detail is more road specific on Sunset stuff. Older brass has become much cheaper as buyers want to have electronics pre-installed rather than learn to do it them selves.
What DCC system? I want user friendly, easy to read etc. Big hand friendly.
They are all good and bad. The biggest problem you have is that the designers often write the user manuals. therefore they know the stuff so well, they make assumptions in their explanations inadvertantly. This sometimes make them hard to understand. The best advice is to get a system that other modelers in your area use. That way you can find someone local to ask questions and give advice. This is especially true as you begin. Once started it all starts to make sense. Also with local guys, if you have a problem, they may have seen it and fixed it. Most system, including NCE and Digitrax, have large "master" throttles that you can program the system with and program decoders. They also have smaller utility throttles that are just for running trains. These smaller ones work really well and are not as confusing as the master throttles for day to day use. The CVP system I know does programming on a big panel, and their throttles are more like the utility throttles.
NCE, Digitrax, CVP (EasyDCC), and Lenz are major suppliers. MRC has a low end system that I don't much about. You should look at each one and hold and fiddle with the various throttles to see what you like. One feature of the Digitrax utilitly I like is the reversing switch is a togle with center off, so you have a definite stop when you a loco to stay in one spot.
Any dealers out there who discount off of MSRP for Sunset Models?
It so nice to have this distraction thank you in advance for your help people.
