After spending all day yesterday in the storage yard at North Yard, it is now time for this Big Boy excursion to return back to Cheyenne! UP 4014 is putting on a fantastic show in the early morning as it heads west on the Moffat on the North Yard Siding. So yes...Big Boy has officially run on the Moffat Tunnel Sub! But it will only get as far as just west of C&S Junction so it can back down Bypass 2, across the Belt Line, to the Greeley Sub.
