Who, if anyone, has tried to take photos of the walls rushing by inside the Moffat Tunnel as their train was going through it?

Your answer is in the photo above! :giggle:I wonder too how dark the walls are inside the Moffat after 86 years of train engine smoke.
And all the time I thought it was a blackout in the coal mine!Actual photo taken in the Moffet tunnel 12/27/14. Awesome, eh?
With flash and it's effective shutter speed, you might want to opt for a smaller (higher number) f/stop for depth of field...you are guesstimating the distance!Your shot of the Cascades tunnel is encouraging.
I'm going to try using an off camera, hot shoe flash unit with a Nikon D300s.
I will manually focus on something in my roomette, and I'll start with the camera set to ISO 400, 1/250, f/5.6.
What would be nice to know is the approximate speed of the CZ while it is in the Moffat Tunnel.
It looks like the Moffat Tunnel is 18 feet wide.
Amtrak Superliner cars are 10.2 feet wide, so I'll need to focus at a bit less than 4 feet.
With the flash unit manually set to 1/8 power and a wide angle beam, I should get a flash duration of about 1/6000.
If I can use 1/16 power, the flash duration will shorten to about 1/10,000 which should be plenty to 'stop' the tunnel wall.
I'll chimp the first shot on the rear LCD and adjust from there.

Yes, thanks!
I shouldn't have to make the aperture much smaller to have an acceptably deep depth-of-field, even though I will likely use a longer focal length lens than the 18 mm I was planning to use out the side of a roomette.I'm kind of a math geek, so with f/stop being fractions, to me f/8 is a smaller/lower number than f/5.6.With flash and it's effective shutter speed, you might want to opt for a smaller (higher number) f/stop for depth of field...you are guesstimating the distance!
BTW, this was taken with an iPhone 4s
Thanks for posting the photos.Remember that you need to remain in whichever coach or sleeper you are in for the whole duration of the Moffat Tunnel, they like to keep vestibule doors shut to keep out fumes!

So if I am at the railfan window before we enter the Moffat Tunnel I'll be able to stay put there for the 6 to 10 minutes we are in the tunnel?
Well, yes, but it would be polite to share it. While you are in the tunnel, the only candidates for sharing are the occupants of the last car, since no one should be entering.So if I am at the railfan window before we enter the Moffat Tunnel I'll be able to stay put there for the 6 to 10 minutes we are in the tunnel?
No sweat. I am always polite, and would be very amenable to sharing the window.Well, yes, but it would be polite to share it.So if I am at the railfan window before we enter the Moffat Tunnel I'll be able to stay put there for the 6 to 10 minutes we are in the tunnel?
I have been on the railfan window going through Moffet Tunnel with 2 other shooters and we had plenty of room to get our cameras up and all get decent shots as we came out of the Denver side of the hole. If everyone positions right, you can probably get up to 5 people comfortably on the window.No sweat.

If someone else is there before me, I hope they do the same.
