There's an amazing piece of engineering in Crawford Notch, New Hampshire that was built in 1875 and is still in use today.

Over 100 years ago, the Portland and Ogdensburg Railroad built the Frankenstein trestle to travel 520 feet and over and 85 feet above a ravine at the bottom of Frankenstein Cliff.

The line later was named the Mountain Division and was operated by the Maine Central Railroad which is Pan Am Railways today. In 1983 the line was abandoned and today is used by the Conway Scenic Railroad for passenger trips from Conway to Crawford Notch with a spectacular view along the way of the White Mountains.

What most people don't get to see is the straight forward view of crossing this long and high trestle. There are only two places on the train to get an unobstructed view of the approach to the trestle. One is in the dome car named Dorthea Mae that gives first class passengers an unobstructed 360 degree from the top atop the car. The other is of course from the cab of the locomotive where the engineer operates from.

Lucky for us, several years ago, someone shot some video from the can of the locomotive as it crossed Frankenstein Trestle, showing us an often unseen perspective of this amazing feat of 19th century engineering.
