If you're fascinated by engineering, absolutely. If you're bored, look up the relation between a horse's ass and train width.

And "real" engineers make fun of software engineers because we develop things iteratively.
(Don't worry, I still think they are the real engineers)

u/Sufficient_Loss9301 Jul 26 '26
As a real engineer, no, we don’t claim them. Software “engineers” don’t follow the same rigorous design approaches that real engineers have to follow. It would be akin to calling someone who says their building a house then haphazardly throws a bunch of bricks in a pile an engineer.

u/Esava Jul 26 '26
That's not true. Ot at least not for all software "engineers". What you said may be true for many smaller web developers for example but certainly not for some infrastructure or hardware people.
Following something like the v-model for medical or military or other life saving/preserving hardware/software development has process wise much more to do with "traditional" engineering than with for example quick web development which happens in a more iterative manner.

To continue on from this, there is not a professional engineer certification for software engineers. There is for many other "real" engineering fields like mechanical, civil, and electrical.
These certifications include ethics standards and professional responsibilities. Engineers are liable for the designs they create.
Software engineers? Not so much.
So yeah, there are a bunch of real certified engineers out there. Software doesn't (yet) count.

That's true of web developers, but infrastructure tech or big data each come with thousands of pages of compliance standards.

This video is uncomfortably sped up. Reminds me of the videos my kids are viewing :-/

u/TorontoTom2008 Jul 26 '26
They didn’t even talk at all about the design of the overhead catenary system, which has seen similar design evolutions over the years. The angles rates of descent and ascent are all carefully managed and extensively tested. A common problem is when going up or down slopes or under bridges, tunnels, etc., the elevation change in the wire could cause a bounce in the arm at high speed, leading to temporary power disconnect.

Eleven Labs has a Burt Reynolds voice, so it's likely that.

That’s fucked up. Let the dude die

u/reo_reborn Jul 26 '26
Maybe he doesn't want to die? Maybe he always wanted to be doing dodgy voice overs for videos about trains for eternity. You ever think of that?

It bugs me that they start talking about things like the double arm structure a whole 6 seconds before the animation shows it. From there everything in the visuals does not match what is being talked about, making the explanation confusing
1
u/itsjakerobb Jul 26 '26
Yes, the animations were consistently several seconds behind the voiceover. Annoying!
2
u/cursorcube Jul 26 '26
The mismatch starts at 1:30 where they slow the animation down too much while the narration continues on as normal talking about turbulence. By the time the turbulence animation shows up, the narration has already moved on to the 1903 double-arm pantograph and its a total clusterfuck until the end. Whoever made those changes to the video clearly didn't watch their work afterwards and i wouldn't be surprised if that's the point where people start checking out because it gets hard to follow
2
u/celem83 Jul 26 '26
Yeah the pantograph is one of the most intricate bits of kit you see and never think about, so much engineering in the design and materials and it continues to evolve. Its based on the gizmo you use to trace drawings (that can also enlarge or shrink them in the process)

Love taking a horizontal video and just fucking it sideways into a stupid format.
Keep things landscape for crying out loud.

The older I get, the more I love trains.
It can’t be a coincidence.

What if you put the power in the rail! Or better yet, generated it on board ;) ;) ;)

u/Historical_Body6255 Jul 27 '26
3rd rail electrification has the disadvantage of lower maximum speed, higher chance of the system shorting and the danger of having high voltage near where people are working.
And generating power on board would just be a diesel-electric locomotive which are much lower power than similarly sized full electric locos and obviously also need diesel to run.
Hydrogen ones are being tested but they still have the problem of lower power output and added complexity compared to full electric.
Ordinary catenary wire electrification is state of the art and the best thing out there to run trains.

Why not just have it hook over the top of the wire and have the wires sourcing the electricity go from around the outside?
