I got to thinking, model RR is as passionate as politics and religion. So what is your favorite war? 1. DC vs DCC 2. Kato locomotives vs. "anybody" 3. Kato unitritack vs. other track 4. code 80 vs. code 55 Any others? I think the DC vs DCC gets the most people worked up. I think it is as passionate as the pro/anti abortion debate. So my thought (just for fun) is what is the biggest war? Feel free to add something else.
