The safe movement of excess-dimension (High & wide) traffic is planned by the carrier. Dimensions and fouling points have been measured by a "clearance car", or equivalent equipment. http://www.prrths.com/philadelphia%20cha...Story.html, and are compiled/filed for the route/line of the move. The route is meticulously prescribed for Dispatchers and crews who will move the item(s), often in dedicated train movements. Locations are pointed out for special "Walk-by" moves, "stop-in-the-wide-spot-wait" orders, "adjacent-tracks-clear", "do-not-pass-moving-traffic", etc. An occasional "Curve-ball" like a clearance move could make an operating session a real challenge and break up any "complacency" in the crews. You could also paint the most problematic part of your H&W with a fragile coating to show any inadvertent scrapes, if you like assessing "Brownies". BTW: How wide are your track centers in your chosen scale? Bob C.
