What I Learned Today

Today I had the pleasure of visiting the Pasadena Museum of History. I went to check out their exhibit on railroad-inspired art. It was delightful! Among other things, several of the pieces were inspired by the very steam locomotive that I got to operate a few weeks ago (see art at right!), as well as other engines and people from the Nevada Northern Railway.

One artist whose work I enjoyed was Bradford Salamon. The first item in the gallery is a dynamic locomotive he painted (titled “Unknown Adventures”), which sadly I cannot find online or on his website to share with you (and photos were not permitted). It was accompanied by a charming statement describing how he enjoys painting “portraits” of objects, not to reproduce the objects, but instead to trigger a memory or feeling associated with them. He paints typewriters, phones, radios, cars, … and trains. Here is one of his trains that I was able to find:

There were also several woodblock prints from Japan that were commissioned to get the public excited when trains were first introduced in Japan (~1850s). Because they were commissioned before the trains actually arrived, and none of the artists had ever seen one, they often copied from U.S. or British publications that showed steam engines… and in one case a steam fire-engine (to put fires out)!

One artist copied from a picture of a train on the Panama Railway, in which one car had “U.S. Mail” printed on it; in the Japanese version, this became “U.S. Maus” (‘maus’ happens to be ‘mouse’ in German). The gallery showed the source images that the artists had used, and you could definitely see how “Mail” could be misinterpreted as “Maus” if you did not speak English!

Here is the Panama original (but not at high enough resolution to read the relevant letters):

Now I want to ride the Panama Railway! You can – it’s a one-hour ride that costs only $25, and includes an open-air viewing deck! Time for a trip to Panama? :)

I recently got to drive a steam locomotive! The Nevada Northern Railway in Ely, NV, allows you to Be the Engineer for a 14-mile trip up and down hills, through two tunnels, and across several road crossings. This is an incredible experience – visually and physically!

(By the way – I learned that you “run” or “operate” an engine, not “drive” it, since no steering is involved. But that is how they describe the experience to newcomers :) )

Did you ever see such a beautiful engine?

NN 40, built by Baldwin in 1910

Before climbing into the engineer’s seat, I had to study a 122-page rulebook and take a short (open book) exam. I learned about whistle signals, hand signals, speed limits, track warrants, air brakes, and more. I learned radio protocol (interestingly, it’s backwards from typical airplane conventions; you announce who you are and then who you want to speak with, e.g., “NN 93 to NN Conductor 93, over”). In addition, “the use of ten codes” (I assume this means things like “10-4”) is prohibited.

I also helped get the engine ready for action. The rest of the crew gave me small jobs, like greasing the many bolts that connect rods and other pieces, and refilling the oil reservoirs. Meanwhile, they stoked up the fire in the boiler, cleaned the engine, filled up the tender’s 6000-gallon water tank, and ensured we had enough coal. The steam engine goes through 75 gallons of water *per mile* and consumes about a ton of coal in the 14-mile trip we did!

After three hours of prep, the engine was ready to go! I climbed up into the cab and learned how to start and stop the engine, then practiced this while we were still in the railyard.

The primary controls are the throttle and the brake. The throttle is a squeeze lever with many (~20) detents. Bouncing along, it requires some fine eye-hand coordination to move it precisely to the desired notch. It, too, is backwards from the throttle on an airplane: moving it out (towards you) gives you more steam, not less!

The brake is a smaller handle, easier to manipulate. If you want to slow down, you move it to a setting that allows compressed air into the brake cylinders, pressing the brake shoes against the wheels. You monitor how much brake you are applying through a pressure gauge. Then you move the handle the other direction to release the compressed air (you can hear it hiss out) and the wheels resume unimpeded motion.

The massive locomotive responds slowly to control changes, so both controls are best applied with careful anticipation of the upcoming track – its grade, any curves, preparation for tunnels, etc.

There is also a reversing lever that is mounted vertically in the floor. As one of my books warns, “A strong arm is needed for the reversing lever!” It has a more subtle effect on locomotion by altering the amount of steam that gets into the piston cylinders on each stroke. You want it set full forward to get moving, then back it off for “cruise” to achieve more efficient operations.

And we were off! We left the railyard and climbed a gentle hill. We went through two tunnels and several road crossings. For each crossing, I blew the whistle – LONG LONG short LONG! Mike, our fireman, was busy shoveling coal as needed, injecting more water into the boiler, and ringing the bell through all crossings as well. What a delightful noise!

We used a GPS-based speedometer to track our speed, which stopped working each time we went into a tunnel. However, after a while you get a feel for speed based on the sound of the pistons (and such a lovely sound it is). Pistons mounted on each side provide the driving power for the large wheels. Each wheel gets driven twice per rotation (unlike engines in cars, airplanes, etc.):

In addition, the left and right wheels are offset in phase so that one side gets maximal torque when the other is at minimum (end of its stroke). So what you hear is CHUFF-chuff-chuff-chuff as the pistons go right-forward, left-forward, right-back, left-back, for a smooth continuous overall motion.

At the top of the hill, I gave the controls over to John, the engineer who was training me, and he traced our way through a “wye” (track set up to enable a three-point turn by an engine), which got us set up to return back downhill.

We then continued back down the hill to return to the railyard. The whole trip took about an hour and 15 minutes. After the initial learning curve, it got very comfortable to roll along and listen and respond to the chuff of the pistons as needed. My mind quieted and I filled up with the pure joy of the moment. What an overwhelming experience!

Thank you to Richard Ondrovic for taking these fantastic photos!

Here’s a neat idea – use composting techniques to take care of our own dead bodies.

In this TED talk, Katrina Spade makes a compelling argument for a new way of managing the corpse part of dying. I’ve long been a fan of cremation over burial, for the reasons she explains, but she also makes good points about the downside of how cremation consumes a lot of energy and generates, effectively, human ash pollution.

The idea of “re-composing” bodies, in ways that allow your molecules to be broken down and eventually used to nurture new life, is refreshing! I also like the idea that bereaved family and friends can have whatever kind of ceremony they like as part of the send-off of the body. For those who like to visit gravesites in remembrance of those who are gone, why not designate a location of positive memories with the deceased (a favorite beach or park, or the site of a graduation or wedding proposal or other significant event), or even have a shrine set aside inside the home (I’ve always liked this idea anyway).

Wired wrote an article about this last year that contains some diagrams about how the envisioned recomposition center would look and operate: Inside the Machine that will turn your Corpse into Compost

And for the current status of the project, check out Urban Death Project (a slightly more creepy name than “Urban Recomposer” or other alternatives). They already demonstrated success in composting six cadavers, and it looks like they are starting the next pilot project this month. This will be fascinating to follow!
