This is a fun series, but has been getting increasingly bizarre, even by its own standards.
I kinda wish they put a little bit more effort into the anime (overhead wires, signals, correct tracks, etc.) but the fact that it all takes place after the 7G event makes these issues handwaveable.
Yep. Biden and administration has been improving stuff for both freight rail and passenger rail, possibly after letting them getting away with being too lax on safety. If he gets another term I really hope they can bring back Conrail which would bring back NS in good hands.
Wow. This is something I have never heard of before but it conceptually makes sense albeit I am a have no idea how long a tank would run a train for. Would love to learn more too, so please link is to whatever it is your are creating. Hoping a video on the topic.
Thanks! So far that site seems to be the best source of information I’ve been able to find (the Wikipedia article seems to mostly be a restated, trimmed down version of it) but there are a few other articles online I’m trying to vet for accuracy.
I’m especially interested in this quote:
“A fireless soda engine, together with evaporating apparatus, has been at work on the Aix la Chapelle-Burtscheid tramway for the last half year. In order to test the working capacity of this locomotive engine, and the consumption of fuel on a certain day, the Honigmann locomotive engine was put to work this day from 8:45 o’clock am till 8 o’clock pm, with a pause of three-quarters of an hour for the second quantity of soda lye. The engine was, therefore, at work for fully 10� hours, viz, 5� hours with the first quantity, and five with the second. The distance between Heinrichsalle and Wilhelmstrasse, where the engine performed the regular service, is 1 km, […] This distance was traversed sixty-four times, the total distance, including the journeys to the station, being 66 km.”
So it sounds like it ran for about five hours and traveled 33km on its load of caustic soda (I’m not sure at a glance which flavor chemical) and only took 45 minutes to refuel and come back up to temp.
And these were early designs, basically prototypes (though granted, the folks in that time making them probably knew a ton about steam locomotives). I imagine they could have been improved with time to study and refine the designs.
I’m not sure how well the boilers stood up to containing hot caustic stuff, but perhaps materials science has developed enough to help protect against that.
I’m writing and making visual art in the solarpunk genre, which tends to heavily emphasize trains and other public transit. But I want to broaden our options a bit beyond just electric trains. When I first heard about these, I felt like they’d mix super well with another invention of that time period, the mirrored solar concentrators used to run steam generators (some of the earliest solar power).
After all, one of the biggest disadvantages of the caustic soda locomotives was that it took more coal to dry the soda than to produce an equivalent amount steam directly with coal. But you don’t have to use coal. These 1800s mirrored dishes only require mirrors or polished metal and math to make (plus some simple motors and electronics to get them to follow the sun) and they could dry the soda for free. A lot of my focus is on less utopian, rebuilding societies, so trains and solar concentrators built with 1800s technology seems like a good place to start.
I’m going to start with a picture of a stop along the tracks for replenishing the soda in this style
plus a description. And I’m hoping to work them into a fiction story and a tabletop campaign.
As for the technical side, I’m not sure on whether they’ll be draining the diluted caustic soda and pouring in fresh, whether they’ll be drying it inside the locomotive’s boiler using superheated steam generated with a solar boiler besides the tracks, perhaps swapping locomotives to avoid delays, or even swapping boilers as someone on reddit suggested. If I go with swapping the soda, probably the boiler tank won’t actually be inside the dish, but nearby, with the steam from the dish heating it.
I hope that helps, I’m very new to this technology and am already trying to mix it with other stuff so we’ll see how it goes.
Considering that most of the descriptions I’ve seen of drying the caustic soda mention pumping superheated steam through it, and that almost any of these systems, or something like these modern ones could produce that, there’s probably lots of ways to match these trains to analog solar power.
Oh wow. What a great reply and a super cool project you are working on. You have inspired me too as one of the attractions in my VR Theme Park I am Imagineering is about trains and I would love to add a foot note about these. Thanks so much.
You know, if I had millions lying around I’d want to build or buy a small <10km line in rural buttfuck Saskatchewan and ride train cars around, just for myself and letting people that made it here use it for fun. I haven’t tried estimating how much that would cost.
Have a look at the West Coast Express, opened in 1995 from Vancouver BC to 43 miles out at an estimated cost of 40 to 80 million Canadian dollars, equivalent to 53.4 to 106.8 million of today’s USD. There were musings of it as far back as 1971, but it sounds like design started sometime after 1981 and construction started in 1994, finishing late 1995.
The price tag would include 5 engines and 5 sets of bilevel railcars, leasing tracks for CP and BNSF, building a handful of turnouts and sidings to hold the trains when out of service, build or contracting wash and maintenance facilities, maybe some small track and signalling upgrades along the route, and station facilities in 7 places.
Another example is the Rail Runner Express in New Mexico that runs 96.5 miles from Santa Fe to Albuquerque. The NM Governor Richardson announced it in August 2003. Construction began in October 2005. The first portion of service began in July 2006 and the full line went into service by December 2008. The cost to build the line was about 285 million USD total equivalent to about 438 million USD today. A operational deficit of 10 to 20 million USD annually was reported and criticized, but roads and bridges of that length cost as much to maintain anyway.
This hugely depends on many factors. What quality should the rail be? Do you transport freight at 30km/h or pasenger rail at 200 km/h? Is there electification involved? How is the soil along the tracks? How many trains of what type do you need? Do you want electric train protection and signaling? How nice do you want the train stops to be? Does it cross property of private individuals that you need to aquire?
I just want to say that this is not really a question that has an answer since it depends on so many factors. You also have to think about regulations for rail traffic. Building a rail line in your backyard isn‘t neary as expensive as one you use commercially because of safety standards you have to comply with, which is a good thing.
Oh and even if you could specify a project, i still would have no clue since i‘m not a project manager nor civil engineer, just interested in rail and trains :D
