Seacaucus Junction has them, I think they were installed new when the station was built new about 10 years ago.
Also.. the Starbucks Roastery Room in Seattle has one, it changes to announce which coffee is currently being roasted. Kinda fun.
And that brings up an interesting point... why does Starbucks have one? Cause these cool vintage things are quite "hip" now a-days with the Starbucks core audience, which is, young students and young professionals. The same core audience of Apple computer. Companies like Amtrak could do alot to create a "vintage cool" transit system. I'm not talking about vintage like a museum.. they will still want wi-fi, power outlets, and other modern comforts. But they will want them provide in an "I can instagram this and make it look like I'm super cool" enviroment.
