Mike...I take it you are renting a backfill compactor "turtle" and/or "jumping jack(s)", having run them in my utility contractor work days.
How many weekends are scheduled to fill the washout hole up to track subgrade level?
Is further mainline extension prep work on tap this summer/FWW?
Busy WW&F work is being compared to the fast return of Denver, South Park & Pacific ng steam to Como, CO, their quickly-rebuilt turntable in front of a renovated, 1879 classic 6-stall stone roundhouse, with just-trucked-in, rebuilt 2-6-2 woodburner #4 "Klondike Kate" and a rider gon, giving rides to a crowd of local folks last weekend on just-built 3' gauge track a couple hundred feet between their recently rebuilt depot, and the 'house where Kate now lives.
As with WW&F, much more work is also planned there by a crew of mega-motivated Rocky Mountain railfans.
