“Peek-A-Boo”
What is an old game to be played with any infant is the type
of weather day today. Big puffy clouds up on the Curve this afternoon as Day
Three rambles on. When that sun does pop out, it sure does feel quite comfy. And
there is a pretty good breeze about 10, maybe 15 MPH with the gusts. Still, it
is a beautiful day.
Breakfast this morning was at one of the Sheetz Convenience
stores that dot Altoona. There are no 7-Elevens around here. Sheetz, with a Z,
was here when I first arrived back in 1989. But man have they changed!! What
were once small 300 square foot at-best stores with maybe 4 fuel pumps are now
like these large multi-purpose convenience stores.
At least a dozen fuel pumps
for cars, 4 more for the diesel variety, and just about every kind of snack
under the sun. I think I counted about 24 different types of coffee, freshly
ground and brewed every morning. At least a dozen frozen Slurpee type drinks,
lots of sandwiches, pastries, potato chips, you name it. The powers-that-be
behind these stores have truly out done themselves. Friendly, smiling faces
behind the counter. So if you are in Pennsylvania and travels thru cities like
Altoona, search for them on Google Maps on your iPhone and get the directions
to the store nearest you.
Once out of Sheetz with a cinnamon bun and 12 ounces of
whole chocolate milk, it was time to head downtown to where the Norfolk
Southern mainline slices thru Altoona. One of my discoveries with Altoona is
that the Station Shopping Mall is no more. It has been taken over and
repurposed as part of the Blair County Medical Center. Back in the days of the
mall, there were a few places where you could sit back in your car or on a
bench and watch the action roll by. Well, there are 3 small overhangs where you
can sit down and watch the trains roll by, provided you don’t mine looking thru
the wild grass.
There are 2 overhead walkways that will allow you to cross over
the tracks. One behind the medical center that takes you to the Altoona Amtrak
train station and one near a parking garage which connects with the back yard
of the Pennsylvanian Memorial Railroad Museum.
I managed to snag a few pics of
an eastbound freight that was slowly rolling into town after it had its helper
locomotives cut off just west of me.
And while walking back to my car, I met a gentleman
who was recording a pair of helper locomotives speeding west out of town to
head back to Cresson near the Gallitzin Tunnels to help another eastbound down
the Curve. His name was Hans and he came from a town just north of Buffalo, NY
in the province of Ontario. He had a broadcast quality Panasonic camera
complete with the fluffy cover boom mic on top. I waited patiently for him to
hit the stop button as professionals usually do. We spoke of our railfanning
efforts and Hans was getting ready to head back north. As a parting shot, he spoke
of how we and he pronounce certain words and place names. DuBois is said differently.
HE also mentions the mountains known as the Grand Tetons. How we say it in
English is one thing; how the French Canadians say it is another. And the
French definition of Grand Tetons should not be said in mixed company. Other
than that, I bid Hand ado and headed over to the east side of Altoona.
There along Porta Road is what is known as the Brickyards
grade crossing. Here is where the eastbounds roll slowly into town with the
engineer keeping his train at a controlled speed. Once around the 70 degree
bend, the train will be in downtown Altoona as it rolls east. Helpers are pulled
off about a mile east in downtown. The westbounds are another story.
Once the
engineer had all of the slack pulled out of this 125 car empty unit coal train, it is Run-8 (full
throttle) as the train climbs as quickly as possible before the 2% ruling
westward grade starts to take ahold of the train. What was a very “fast” 30MPH
is slowly being cut down as the train climbs west. As the last car clears the
crossing, the train is down to about half its speed as the weight of the train,
the 90 degree curve to the west of this grade crossing before Horseshoe Curve and that grade take
hold. Yet somehow, that train will make it run around Horseshoe Curve and
continue west to Pittsburgh and beyond.
Once I make a pit stop and grab lunch, it is back to
Horseshoe Curve and an afternoon of watching the trains roll by. Still a good
amount of puffy clods and that peek-a-boo sunshine. Temps are somewhere between
75 and 80. A great Indian Summer Day.
One thing about being here at the Curve: it can be very
quiet for minutes at a time. And then all hell breaks loose as you see in the
following pics: a double stack westbound coming up the curve and at the same
time, a 93 car eastbound slowly comes down the Curve. A “meet” if you will.
The
westbound had a pair of 4400 horsepower GE (General Electric) locomotives
running Run-8 with a pair of EMD (Electro Motive Division of General Motors) locomotives
to keep the train moving and slack action to a minimum. Eastbound was a
foursome of 4400 horsepower GE’s (with an out-of-towner from the Union Pacific)
running in full dynamic braking and a pair of EMD’s on the rear to keep the
braking in check.
A word on how trains stop. When running on flat terrain, the
brakes on a train will usually do the job. The brake shoes are kept off of the
wheels with compressed air which comes from the locomotives and runs the full
length of the train: what we call the “train line”. If by chance there would be
a separating of the train, the escaping airs causes the brake shows to clamp
down on the wheels and effectively stop the train. Once the culprit of the separation
is found, the air is pumped back up and the train is on its way.
Coming down the hill is another story. In a locomotive, the
engine, known as the prime mover, spins a generator which supplies DC voltage
to the traction motors on the axles to provide the pulling power. As a
comparison, the voltage to light a 100 watt light bulb is 120 volts AC with a
current of about 1 amp. In the EMD helper locomotives, the generator there
provides 600 volts DC with a maximum long term running of 1500 amps with a
short term running of 2200 amps maximum. When it comes time to go downhill,
dynamic braking comes into use. This is where the traction motors on the
locomotive are turned into generators. The voltage generated by the motors is
fed into large resistor grids usually located bind the cab or midway on the top
of the locomotive. The heat that is created by this braking is dissipated as
heat and large cooling fans keep the heat from burning out the resistive grid.
On certain days, you can actually see and feel the heat from these grids. Add a little light brake shoe braking and done. Quite
impressive.
The day carries on under sunny skies. And it seems we have
more visitors. There was an Amish family of 10 that came up with their picnic
baskets and set out their spread under one of the trees picnic tables. And it
seems a bus came thru with a bunch of senior citizens. All quite chatty and
taking pictures of the trains rolling by and getting a picture taken by old
GP-9 Pennsylvania locomotive 7048, which sits here on the Curve for those past
and present who make the Curve work every day. Safe to say I saw maybe over 150
visitors to the Curve while I was here this afternoon.
And for added excitement, we had a mile and a quarter long
eastbound double stack train literally stop on the Curve. Seems in downtown
Altoona, the Norfolk Southern dispatcher out of Pittsburgh reported that there
was a broken rail on the track that this train was supposed to use. The train
was stopped at the Brickyards crossing while the track maintenance folks did
their thing. It was then decided to run the train around the affected area.
When the engineer was given the OK to roll east and he took the brakes off, you
could hear the brakes release in order from front to back. As the train groaned
to life, it rolled very slowly until it reached its normal downhill speed. Very
rare to see a train stop going downhill. Even more amazing to see how it was
safely stopped and then started again.
Anyway, so ends Day Three. We have one more day here at the
Curve before we head to our next stop on Thursday afternoon in the railroad
town of Ashland, Virginia. Tomorrow we’ll talk about train weight. You’ll be
surprised what train cars can hold. And we’ll show you pictures of one very
special unit train that came thru here. Later later.
I’m Philip J Zocco. On the Road. In Altoona, Pennsylvania.
