I'm not really surprised that DCC is winning, as the built-in interior cabs feature strongly across the board, and are used in quite a few different styles of locomotives, especially diesel ones. I've downloaded all the interiors from various diesels and electrics from North America, Europe and Australia to assist me in remembering how to operate each one separately. But as you may have the same cab for 6, 7 or 8 different types of loco, it's easy to remember how to drive them all, after taking a few driving lessons....:hehe: So, unless you have a desk mounted clipboard with every detailed cab interior printed on it, to assist in what switch and lever does what function, I'd bet many will opt for the easy option and choose DCC....
And yes, I'm a little suspicious why Tony H. has started 6 polls today on various features, something's up......:hehe:
