I have not seen this post card picture for a lot of years. A friend of mine just sent it to me. Yes....it's the Colorado Central Narrow gauge Railroad in Central City. Since #44 is still lettered for the F.I.de C.A.in Central America, I'm assuming this picture was taken in late summer 1968 or early summer 1969. The train is heading to the Central City "depot". The yards and C&S 71 and it's equipment were a few hundred feet in front of #44.
