With the photo date being less than a week ago, I'd guess the cars are in some sort of museum collection, with steps to access stored items inside (and skylights so the stored items can be seen.)

It is a collection of equipment in Gorham, NH, including ex-Steamtown (VT) Eastern Gas & Fuel 0-6-0, including chopped cab for close clearances. There is a North Stratford 40' boxcar, and B&M F7 along with a few other pieces.
