B&O Hogback Tunnel near Ferndale, PA

(Satellite, see below for a diagram)

Street View, Apr 2025

Rust Belt Railroading posted four photos with the comment: "L-100 strolling through Hogback  Tunnel heading north into Johnstown. The track speed through there is 10 mph. It is located in Ferndale across from the greenhouse on Eisenhower Boulevard."

Matt Thomas: I remember we would have to fold the mirrors in or we would hit the sides of the tunnel. It’s a tight squeeze.

Johnstown Tunnel on the former Cambria and Somerset Branch of the Baltimore and Ohio Railroad south of Johnstown Pennsylvania

Steve Lindberg: I thought it might be the coal train out of the current Windber coal mine , but not. It is still an active line though; been there many times with students to examine the local rock layers at a very well exposed hillside cut, and along comes a train.

Hsoj Duell: Steve Lindberg this tunnel is on Eisenhower Blvd and a local from Rockwood comes through daily to service Safety Kleen and Pepsi by Dale Oxygen and Gautier and interchange with the C&BL . The coal trains are Norfolk Southern and go up through Elton.

Frederick L Leer: It's known as Hogback Tunnel to the railroad. It's deceptively short but you can't see through it due to the sharp curvature of the track.

Bob Leverknight: Hogback Tunnel.

When EMD's Train of Tomorrow was on it's national tour, it was to be transfered to the PRR off the B&O at Johnstown.

However.

Hogback had other ideas.

The Moon Glow sleeper got hung up inside the tunnel, creating a pretty big gash down it's side.

The B&O crews managed to get it out, placed on display, then continued on it's merry way.

Later, the UP purchased the dome train set for use as the (unofficial) City of Seattle streamliner. That dent was still there!

Fast forward to the late 1980s.

CSX had moved dispatch and power assignments to Jacksonville Florida.

One fine day, the Johnstown Jet was called in Connellsville, and had an SD-50 as the power. The crew tried to point out to the recently moved from the ACL Road Foreman the timetable specifically stated: "no six axle power west (compass north) of Hollsopple because of clearance restrictions at Krings."

The Road Foreman took the throttle.

Sure enough, Hogback caught that big SD!

Apparently, "told ya" was uttered.

Now.

Memorial Day, 1957, there was a fantrip from Cumberland to Johnstown featuring EM-1 7600. (If you see photos of this engine sporting a graphite boiler front, it was from that trip and shortly after.)

It managed to squeeze through, as did thousands of Bethlehem built TTX 89' flat cars which were delivered across the S&C.

The truck center distance is the secret to long stuff making it through.

Thanks for coming to my home of Johnstown and doing all that you did. Love what you do!

"Brookfield Renewable’s hydroelectric power plant plays an integral role in the Lake Wallenpaupack community; in fact, the lake was created because of the plant itself. In the early 1900s, engineers recognized the value of constructing a hydroelectric station and a dam to power it in the Poconos. The 1,280-foot dam built across Wallenpaupack Creek, was completed in 1927, creating Lake Wallenpaupack. The lake encompassing 5,700 acres is still one of the largest man-made lakes in Pennsylvania."

Upper Delaware Scenic & Recreational River posted

Heavy rains over the last week [first week of May 2025] have caused Lake Wallenpaupack levels to rise significantly enough to warrant Brookfield Renewable to open both spillways. The current height of the Delaware River is 7.87ft and is projected to crest at 13.10ft at 2:00PM Saturday May 10th. Due to the high water, mandatory life jacket wear is in effect for anyone in or on the Delaware River including boaters, swimmers and wading fisherman.

Please also be aware that high water levels can have floating debris and fallen trees can cause dangerous strainers in narrower channels and where the river currents are moving fast. Life Jackets Save Lives, so don’t be caught out there without one! Please visit https://www.safewaters.com/facility/wallenpaupack to learn more about water being released from Lake Wallenpaupack. And please visit the USGS site at Delaware River at Barryville to see real time river conditions as they change frequently.

There is a submersible bridge at each end of the Corinth Canal.

The middle part between the "blue boxes" is what goes down.

Street View, Sep 2014

I wondered why I could not see a bridge in this photo. Then I learned that it was because it is down in the water since boats are using the canal.

In the middle of the canal, the cut is deep enough that they can build fixed bridges over the canal.

You can't see the bridge until about 2:18. You just hear a motor running.
