Very Impressed...

I got to see an Old Pentrex Video about Horseshoe Curve. I found it to be very enjoyable... Also, got to see one of the Test Cars... Did not get to read the side, it was in the middle of 2 boxcars, however, the movie was put together well.

A question though. Why is that ex-pennsy GP 7 there?

I believe that's a GP9 that was donated by Conrail to take the place of a PRR K-4 steam locomotive that was there for years before it was moved to Altoona for rebuilding.
