Big Boy – The ExhaustNotes Blog

Folks my age love steam locomotives. I think it’s because they were still pulling trains and generating revenue when I was a kid. The Lionel thing probably figures into the equation, too. Most guys my age had a Lionel train set when they were boys. I did, and I loved it. Some guys are still into it, like good buddy Steve. Anyway, the point is when I’m traveling, I never miss an opportunity to visit a railroad museum.

A few months ago when we were back east, our travels allowed us to swing by Scranton, Pennsylvania, and visit the Steamtown National Historic Site. It’s part of the US National Park network, but if you don’t have the senior discount card, don’t worry about it. Admission is free.

The tour started with a movie, and it was great. It told a lot about the early days of railroad travel in America, and it had an interesting section on mail cars. I’ll get to that in a second.

The free movie that starts every tour of the Steamtown National Historic Site.

After the movie, you follow the marked path and see several locomotives and a mail car. Some of those photos are coming up (I used my Nikon D810 and the 24-120 Nikon lens for all the photos you see here). After that, the path takes you outside again to see the roundtable. That’s what locomotive repair facilities used to rotate locomotives and put them on the right tracks. Here’s a photo of the roundtable.

It might seem mundane, but the movie told an interesting story about this aspect of railroad history and seeing an actual mail car immediately after was a nice touch.

Another mail car photo. The trains didn’t stop to pick up the mail. Mail bags were hung in each small town, and the mail cars snatched them as the train rolled across America. Interesting stuff.

The locomotives in the maintenance shop were interesting. Photographing these would ordinarily be a challenge because of the dimly-lit buildings and the black locomotives, but the Nikon 810 and the 24-120 lens vibration reduction technology handled it well. That combo has superior low-light capabilities. All of these photos are hand-held shots with no flash.

The locomotives were huge. As a mechanical engineer, it was a real treat to see what the state of the art was a century ago.

The displays included a cutaway locomotive that showed a steam locomotive’s innards. I had studied steam generation as an undergraduate engineering student and like I said, I was a Lionel guy when I was a kid, but I had no idea. This stuff is fascinating.

There was a lot going on inside these things.

We walked around outside and I grabbed photos of some of the locomotives in the yard. This one was obviously unrestored. It was pretty cool.

The rail yard had a Reading Lines diesel electric locomotive on display, too. Most folks just call these diesels, but propulsion was actually via electric motors in the trucks (a truck is the subchassis that carries the wheels, the axles, and the electric motors). The diesel engine is used to turn a generator that provides electricity to the motors. If this sounds suspiciously like a modern hybrid automobile, it’s because it is.

As we left, it was just starting to rain. It was overcast the entire time we visited Steamtown National Historic Site. I was okay with that, because overcast days are best for good photography. I stopped to grab a few photos of the Big Boy parked at the entrance to the site.

Big Boy 4012, one of only 25 ever built.

These Big Boy locomotives are a story all by themselves. They were the largest steam locomotives ever built, designed specifically for the the Union Pacific Railroad by the American Locomotive Works. They are articulated, which means their 4-8-8-4 wheel set (4 little wheels, 8 big drive wheels, 8 more big drive wheels, and then 4 more little wheels) are hinged underneath the locomotive so the thing can negotiate curves. The Big Boys were created for the specific purpose of pulling long trains up and over the Rocky Mountains. They only made 25 of them. We had one here in my neighborhood a few years ago and we wrote about it on the blog.

Which brings me to my next point. I started this blog by saying that folks my age love steam locomotives. I guess that pertains to Gresh and me, as it seems we’ve done a number of ExNotes blogs that include railroad stuff. Here you go, boys and girls.

Pennsylvania is a beautiful state. I grew up one state over (in New Jersey), and a lot of the folks I knew in New Jersey relocated to Pennsylvania because of the more rational tax structure. There are beautiful motorcycle roads in Pennsylvania, too, once you get off the freeways and start exploring. If you make it to Scranton, the place has great restaurants, and like most east coast locales, the Italian food is the best in the world (even better than Italy, in my opinion). Try Vincenzo’s for pizza. It was awesome.

A Vincenzo’s delight. Thin crust, the right toppings, and wow, was it ever goood!

Maybe it’s a guy thing. For me, motorcycles and trains go together like coffee and a donut. There’s the obvious: The travel and adventure suggested by motorcycles and trains. There’s the subtle: The mechanical beauty, be it a locomotive or a motorcycle. There’s the analogy, one I often use for a fast motorcycle: This thing pulls like a locomotive. It’s an expression that makes no sense, considering the leisurely acceleration of a locomotive compared to even a small motorcycle (in engineering terms, you just can’t defeat f = ma). I still use that expression, though. It conveys power, an attribute I apply to my motorcycles.

Like a lot of guys, I grew up in the Lionel era, dividing my drooling between things like the maroon Pennsylvania Railroad GG-1 locomotives that ran by our place and a variety of British vertical twins (all of which I knew had to pull, you know, like a locomotive).

I had lunch one day a few years ago with the guys at our local BMW dealership (I don’t own a BMW, but they let me hang around). One of the boys was pumped because he had seen Big Boy at the Pomona Fairgrounds earlier. Only half-listening to the conversation, I thought he was talking about a hamburger, and then I realized it was a steam locomotive. My Lionel antenna immediately went up and like everyone else at the table, I started paying attention. To cut to the chase, we decided to visit Big Boy after our lunch that afternoon.

As you can see from the photo, luck was with us. We had a great lunch and then we snuck into the Pomona fairgrounds to see Big Boy. I grabbed all of these photos with my iPhone. They would have been better if I had my Nikon, but you go to war with the army you have, and all I had was a phone.

I didn’t know really anything about the Big Boy locomotives, so when I got home I Googled it. These locomotives, and 4014 in particular, have a fascinating story. They are the largest and probably the most famous steam locomotives ever manufactured. Old 4014 has been restored to operating condition by Union Pacific’s Heritage Fleet operation in Cheyenne, Wyoming (the photos you’re seeing here are before the restoration). As part of the restoration, 4014 was converted to use fuel oil instead of coal for the boiler. It was an obvious move. I mean, where do you go to buy coal these days?

Only 25 Big Boys were ever built, and they all went to the Union Pacific Railroad. They were manufactured by the American Locomotive Company in the early 1940s. Their primary purpose was to pull long and heavy trains (up to 4,040 tons) through the Wasatch Mountains and the main rail lines between Ogden and Cheyenne. They were designed for 80 mph, but 60 mph was their normal cruising speed. Big Boys produced 6000 horsepower and God only knows how much torque. They were 132 long (including the tender) and they weighed 1.2 million pounds. The tender could carry 24,000 gallons of water and 28 tons of coal. The locomotive is articulated (it’s so long that the wheels are hinged and can turn with respect to each other to get through curves). Old 4014 was first delivered to the Union Pacific in 1941 and retired in 1961, and during that period, it traveled over a million miles.

Very cool stuff, folks, made all the more interesting by the fact that No. 4014 finished its restoration in 2019 and entered service for special runs. It would sure be cool to take a trip on one of those special runs. That would be a real adventure.
