Are there other photo types you've thought about taking? (I don't know very much about the topic. Rocket launches? Cruise ships? 360/Cylindrical line scan sweeps?)
I assume the train rails and constant motion are part of the appeal of making trains the subject. I can't exactly think of parallels, maybe a factory assembly line.

I never thought about it until seeing these, but line scans yield an orthographic projection in the scan direction. There was a little bit of uncanny valley being able to see parts of the front/back of the car that would have normally been compressed out occluded by perspective.
...and I'll be surprised if I don't see these pictures hanging in a bank/startup lobby at some point!
Your work is extremely beautiful, and I am truly envious of your work, the aesthetic is awesome. I want to do it on the cheap though, with a regular phone as camera.
I think you have given me the directions needed to make some bold steps towards getting what I want out of the 'medium'.
I suppose the subjects moved past the camera perpendicular to the lens direction, so you only see one side.
Are there any examples of what it looks like with a line scan camera when a subject goes past at an angle?
Also, for anyone setting up a tripod with a tripping hazard in public, do consider public liability insurance :)
What lens are you using? Does it have to cover 135 format?
