Gregg sends us another update on the Union Pacific M-35:
The front drop sash was installed Wednesday. Also, in the picture can be seen the mirror that was replicated from photos of the car. It was missing when we got the car in 1975.
Here is an interior shot of the drop sash. Roger Kramer located a pair of latches, and I modified them to fit at the top of the window frame. Thanks, Roger!
