Many model railroaders model the past and there are some who say that model railroading is one of the better time machines invented, especially when it comes to operations.
Here's a typical scene on the Onondaga Cutoff, with train BRSE-1 (Belt Railway of Chicago to Selkirk, NY, leaving on the 11th of the month) topping the grade at CP282 south of Syracuse, NY. This models the daily passage of the prototype BRSE, with locomotives and cars that represent what actually happened.
You can hear and see the lively conversation that surrounds the activity, and it is much like that on the prototype as well. Operations brings a layout to life, and keeps the interest high.
