In my day job I get to play with real trains. My company is the program manager for the upcoming high speed service between Chicago and St. Louis, and I have gotten into several details of that project including specifications for locomotives and cars. Also working on several alternatives to improve multi-modal service on the Eisenhower Expressway near Chicago, including re-doing or extending the CTA Blue Line to the west of Forest Park where it stops now.
Don't have any model trains, but I do read Model Railroader occasionally and am struck with the detail and realism of some of the layouts and panoramas. Singer Rod Stewart is an avid modeler, and his layout is a breathtaking urban cityscape.
Also would love to ride the White Pass & Yukon someday from Skagway, AK to Carcross, YT.
