I stand partialy corrected ... When the old stone flanked flagpole, the old 197 RR tie steps, the gazebo was torn out, the new lighted steps, and funicular was installed ... the old wrought iron fence was replaced with a new (identical) aluminium pointy toped spiked fence, as well as the same type around the GP9.
Your route looks great by the way, and I can't wait to get a look at the trackwork spline points and gradients ... even if I do have to upgrade to 09/10.
Gone is the old PRR signal bridge at MP 241.7, in liue of the new fangled safetrain signal bridge and modern colored signals.
The rock cliff is a dark ignious type granite, with weeds and brush growing out of the outcropping ... I camped out on top of the rock cliff in 1977, and got no sleep, all night long ... confounded squeeling noisy trains on the "Curve" !
Most serious railfans have given up going to the "Curve" as it is all grown up with trees, and they charge admission (even if you walk up), and there is no longer any "Track Shack" food consession stand nor ice cream stand ... and places like Cresson Park, Galitzin Park and Cassandra RR Overlook are better for viewing trains.
I used to think of the Horseshoe as the one and only mecca of railfaning spots ... but in actuality the entire East & West Slope is quite an interesting 37 mile long gradient up and over the Allegheny Front Range.
A band of diehard railfans (Yahoo Groups Altoona Johnstown) chase each and every train up and over the mountain, taking photos and videos of the same train in several different locations.
Many once popular photo locations (such as Alto, Slope, UN, AR, MG, MO) are now strictly off limits, and RR Police strictly enforce the no trespassing laws, and have posted no parking signs, with ejection, fines, and detention while you are logged into the RR police database.
