Narrower gauge locomotive

My brother spotted what appears to be a Miniature Train Company G16 amusement park locomotive in a junk yard while riding the light rail Saturday.
I spotted it on a later trip. It is painted in Santa Fe War Bonnet colors. A G16 is a gasoline-powered, 16-inch gauge engine. The ``Molly'' on the Tiny Town Railroad is a G16, converted to 15-inch gauge.
I thought it was between the light rail yard and the Englewood station on the C/D line but when I went back in the car I couldn't find it. The Winslow Construction Company occupies that spot.
It would be a shape to see this one go.
