I remember reading about this topic years ago in one of the railway magazines, and wonder if any gauge members have tried to do it. The premise is that one takes a special year and day (e.g your birthday, or wedding day etc) and a special place (where you got married, your favorite railfanning location) and try to model the specific day (or morning/afternoon and so on). You don't have to make the place especially accurate: in other words you could try and scratch build all the prototype buldings, but off the peg kits would do just as well. The main point is to replicate the actual trains and train movements. So, one needs to have the same type and number of locos, with the accurate running numbers and liveries used in that yard/station/junction on that specific day. Also, the correct type and number of rolling stock. Getting the correct running numbers on freight and passanger cars is of course more difficult, but research might turn up that information. I guess this could be satisfying to research and set up, but might be somewhat limiting once you've done it!
