When they are removing the rails from the John Galt line, the text on the screen says it is March 31. Nowhere in Colorado would be so green in March nor would any deciduous trees be completely leafed out as the ones in this scene are. In fact, it will be at least another month or two until the leaf buds even begin to swell before producing leaves.

One the back of the hotel door is a standard fire-escape map showing the floor plan of a curved building, presumably the hotel where the interior shots were filmed.
