Upgraded EMD GP20

Here's another diesel conversion from PS1 to PS2.  I've previously shown this locomotive, the EMD GP20, in operation with its as-delivered Protosound 1 (PS1) electronics (http://www.youtube.com/watch?v=Pm6K0MGU3NM).  I've converted it to Protosound 2 (PS2) and by comparing this True HD 1080p video with the previous one, you can see many of the changes, not the least of which is that I'm now running it with the DCS remote control (well, you can't see that but you can take my word for it).  There's much better control of the speed, better sound, full control of the directional lighting, etc.  All in all, it's now a lot more fun to run!  In this video, it's hauling an intermodal train, as you might have seen it doing on main lines all across the country.
