Let's wander into the Hudson Valley. The Moodna Viaduct was built a little over a century ago by the Erie and Jersey Railroad Line. It's the longest (3200 feet) and highest (193 feet at the highest point) railroad viaduct east of the Mississippi.
As the name of that railroad implies, this is how you would have gone from Hoboken to Buffalo in the early 20th century. That route closed down ages ago but there are still commuters who make the long trek between Port Jervis and Hoboken every day.
Part of the Port Jervis Line was wrecked by Hurricane Irene so no trains were passing overhead when I was there. The line has been repaired and brought back into service so maybe I need to make a return visit.
I couldn't fit the big panoramic photo above so here you go.
