I recently had a chance to visit the National NYC Museum in Elkhart, Ind. Located downtown, across the tracks from the (NYC) depot, the museum has a moderately-sized collection of non-operating equipment, plus a large display area inside the old freight house.
The prime attraction is the NYC Mohawk #3001. This locomotive was sold to the T&P where it was modified, and then donated to the city of Dallas for display. Elkhart later traded a GG-1 for it.
New elephant ears are being fabricated to replace the long-gone originals, and one has been recently installed. There's a thread currently in progress on RyPN about this engine.
The cab is accessible and still has most of the appliances.
This auxiliary tender was part of the Freedom Train.
And there's another GG-1 on display. (In practice, this is partly a Penn Central museum!)
And there are several freight cars, work equipment, and passenger cars on display. Several waycars are set up and open to the public, as well as this obs car, set up as a dining car. I have lots more pictures if anyone's really interested.
Finally, they also have a South Shore car, #15. The interior is much better looking than the exterior.
And a 2' gauge park train of some sort, which wasn't running.
The freight house has several large display areas of various types, all well arranged.
And a large toy train layout, which runs only NYC equipment.
Here we have a 1" scale live steam Mohawk.
And an even bigger K4, made from 400,000 toothpicks. I kid you not. You have to see it to believe it.
And I thought this was interesting: a section of strap rail.
If you're in the Elkhart area, this museum is certainly worth a visit.
