Yeah I was wondering about KCS, but I can't think off hand where they run. I know I've seen them in central Illinois though.
Oo. Sorry I didn't see this earlier, Mike. You've probably figured it out by now.
KCS bought the ex-Gateway Western/ex-ICG/ex-GM&O line between East St. Louis and Kansas City, via Roodhouse, crossing the Mississippi on the swing bridge at Louisiana, MO. There's a branch to Springfield. Traffic is very light on the Missouri and Illinois lines... a train a day, maybe?
