It's not readily apparent in this pair of right & left / real & fake (or, like my brain & Willie's, right & wrong) photos from October, 1964

It wasn't until just a few years ago when I read about it here on the NGDF that I learned that the "mainline" spout was another Hollyweird fake. Based on the position of the tank relative to the tracks on both sides, I wonder if the D&RG had originally planned for it to be a two-spouter back in 1881 and then decided it wasn't necessary?
