A recent posting, which I can't find, asked for photos of Liberty Lines Bipolars. I own two, the green one in the photo below that is obviously in need of repairs.
I also own a tri-color one, which you can see twice using the video link below. First, you can see it sitting trackside next to a green "Brute" just 50 seconds into the video of the SGMA layout at the 2010 WGHT Dulles show. Later in the video at the 9 minute mark, it can be seen again this time in action pulling a set of MTH Milwaukee Road tri-color State cars.
