However, it turns out that HSR across the Ridge-and-Valley Appalachians may be easier than first expected. The reason why is because, instead of long tunnels, you just need to blast short tunnels perpendicular to those long parallel ridges. The idea I drafted out starts from Harrisburg station, crosses the Susquehanna on a new bridge at the base of Blue Mountain, curves through a tunnel under the western suburbs to the Turnpike, and follows the Turnpike out towards Tuscarora State Forest, where it turns northward, crossing the mountains in a series of short tunnels and using natural gaps where available to a long tunnel under Blue Knob before rejoining the old PRR main line just south of Latrobe.
110 mph is a very good start and would be a massive improvement. I'm guessing the railroad currently is at 80-90 mph? Just shaving of 30-45 min from a 5½ hour journey between Harrisburg and Pittsburgh would be a huge improvement.

Which also brings up the question why on earth there's no detailed maps showing speed limited of US railroads.

79 mph would be a good bet for a general speed limit. The reason is regulatory: an 80 mph speed limit triggers a requirement for a much more expensive signal system.

However, that said, there are also several slow points. Horseshoe Curve and the Rockville Bridge approaches are two of the obvious ones; there are also narrows on the Conemaugh that has to be a slow point, geometrically, and a couple of other sharp curves that'll have reduced speed limits.

"Proprietary information" ... remember, private railroads own the tracks.

Now all they have to do is straighten the line between Albany and Boston.

Probably less to do with inflation than the remnants of an economic depression a world war, and increasing expectations of comfort and convenience...

Inflation was quite low, on average, between 1906 and 1945.

Also what was the guarantee that the money supposedly saved would be actually used for track improvements and not diverted for non rail expenditure.

Amtrak Empire Line: Penn Station to DV

Quote:
Reverse railfan window view out the back of Amtrak Empire Service Train #235 as it starts its run at Penn Station and travels up the Empire Connection to the Empire Line on the way to Metro North territory at DV interlocking, just past the Inwood Movable Bridge

The Empire Line was the former West Side freight route down the island of Manhattan serving all the industry and docks that used to reside in the city itself. Much of the line was overbuilt with parkland on the northern end and contemporary residential towers on the southern end.

This run sees some speed restrictions across the Inwood Bridge. The train departed Penn Station about 20 minutes later after waiting for a southbound train to clear up after single tracking all the way from DV.

Fun fact: There's a group that's building a brand-new PRR T1, and one of their goals is to test the engine's top speed (apparently, it was rated at 140 mph, which would make it the fastest steam engine ever built, but was never demonstrated at that speed, which is why the Mallard still holds the world steam speed record). Check it out.
