I was wondering if anyone knew of the best turn radius for Emily? I have LGB brass track and her engine grinds on the curves and her tender either grinds of squeals, and her coaches do both I have R1 rated LGB radius turns. 

 so i breaking down and getting dcc, and as you know im well into thomas stuff and want the decoder bachmann uses, since thats really the only one that has the right sounds, now, it took me a while but i finally found the manual for the decoder online, and it asks that i use a 8ohm rated for 3 watts
i was wondering if these 8ohm 5watt speakers from amazon would be okay?

I was wondering how I would change the programming (like whos sound plays) on the sound modules that bachmann sells, with the dynamis system. Some people says you need a test track? Others say you need an add on or something? i'm so confused, does anyone know?

So I have been looking at the Dynamis DCC for my main DCC set up for a while now, but I only just thought of "what if I get another large-scale besides Bachmann that has DCC?" so basically to make a long story short, would the Dynamis system work with other large-scale, lets say a Piko DCC, train?

I was wondering if anyone would know what kind of speaker that I should get to go with the DCC upgrade kit that one can buy to upgrade a non DCC thomas train.

any more news on any new thomas large scale models, kinda hoping the trains they listed on the DCC chip will come in large scale soon.
