Not sure exactly what category this should be in, but I'm putting it in here for now. I'm wondering how some of you deal with bridge traffic. The inbounds / outbounds of industries on one's layout are easy enough to figure out. But I'm having trouble arriving at a good theorem on bridge traffic, which should make up a significant portion of my traffic since the major portion of my layout will be the MOPAC mainline from Wichita to Pueblo through Scott City. If it helps, here's what I'm modeling. Era: 1980 Missouri Pacific: Wichita-Scott City-Pueblo (as noted above, all visible) Santa Fe: Wichita-Dodge City-Pueblo (all in staging except in these three points) Rock Island: Wichita-Oklahoma City (visible in the middle portions only - i.e., Enid OK Okeene OK Dodge City KS) I'm curious what the rest of you do. Thanks.
