I need help. I have done some research but still, I am unsure of what and how to do this. I want to get a DCC system going. I acquired about 70 feet of Aristo track and some switches. Theres also six LGB locomotives (all with single motors) some from starter sets and some in boxes. Of those.. three of them are #2 and the other three are #3 (below). 
They're from a mix of starter sets and single engines. They're all the steam type (no diesels). I also got a Bridgeworks 5 amp throttle/transformer.
So.. Here are my newbie DCC questions..
1. What DCC system will work with all this for an indoor layout? .. I'm setting it up (indoors) in my basement.
2. Could I use the Bridgeworks 5 throttle/transformer with a DCC?
3. Which decoders will work with those Locos? I'm pretty sure I can install them myself
I was looking at different makes of DCC such as Massoth, Digitrax, NCE and LGB and Piko and ... the list goes on. I don't want to spend too much money because I honestly don't have a lot to spend. So, I'd like to keep the price as low as possible.
I did look at the Mean Well LRS 350 24V switchable power, its around 30 bucks, could I connect that (and save lots of money) instead of purchasing an expensive power pack? If so, how do I connect it, what would I need?
I want to be able to run 3 at least locos at the same time.
I'd like to be able to turn some switches on the layout.
Oh.. I don't particularly care about if the system is wireless or not, I don't mind walking around with a wire.
I actually like the looks of the Digitrax throttle but not sure if I can use it anyway.
There aren't any local clubs for me to ask at because I live "in the sticks".
Sorry if I'm all over the place
The reason I got all the trains and tracks and stuff is my Dad recently passed away. I want to continue his legacy and show my kids the trains with the modern technology.
Sincerely,
Dave
