I have seen other photographers sharing photos of Walt Disney World Monorails at night in Epcot using a single flash unit to illuminate the moving vehicle. Without a flash, one could only get a blurred monorail late at night. You know me by now, I had to see if I could light up a monorail using my trusty Nikon SB-600 Speedlight flash unit.
I set up a tripod near the Universe of Energy so I could use Spaceship Earth for a backdrop when a monorail came by. Another reason for this location is the monorails slow down when they enter Epcot allowing me to use slower shutter speeds. The Universe of Energy is closed at night even if Epcot has an EMH night making it quiet enough to hear when a monorail was approaching. When a monorail appeared I tried to wait for it to get to the T in the track (see photos). I got better with each monorail.
I set my camera to use Rear-sync flash (sometimes called second curtain) where the flash is fired at the end of the exposure. This freezes most everything being photographed even if it is moving. Bright lights, like a monorail’s headlight, will still show a streak. The flash’s power was set to full power (+/- 0).
I put my camera in Manual mode and set the aperture to f/5 and ISO to 3200. I used my zoom lens on the scene until I found 82mm gave me a good composition. Used auto-focus to set focus and turned it off. By doing so, the focus will not change unless I moved the camera or hit the tripod. I used a remote shutter release to eliminate touching the camera. The flash was in the hot shoe on the camera.
The first monorail was orange and I took it at 1/30th of a second. I was a little quick on the shutter and the flash did not cover as much of the monorail as I had hoped. I liked how Spaceship Earth looked.

Monorail Green was the second one to enter Epcot. I changed the shutter speed to 1/15th of a second. Notice how the headlight has become elongated in this photo. Spaceship Earth is better exposed and more of the monorail has been lighted. I hit my mark, too.

Monorail Blue was the next one and has an even longer headlight streak from the longer exposure at 1/4th of a second. The monorail is well lighted and Spaceship Earth looks great behind it. The mark is a bit late but I liked it better. I cropped it to a 4×5 (8×10) ratio.

I now know it can be done. I will try it again with a whole monorail as it crosses the World Showcase walkway from Future World. Others have done it with off-camera flash. Something I want to try at Walt Disney World in the future.
Scott, great shots!!
I can remember when “they” would freak-out if you brought in a tripod!
Scott replies: Thanks, Bob. The parks at Walt Disney World do not mind tripods. I have heard some horror stories about Downtown Disney though.
Hello
Can this be done with a point and shoot?
Scott replies: Connie, I am not sure. I know some of the high-end P&S cameras do have a hot shoe for a larger flash unit like the one I used. In that case I would say yes. For a built in flash, I do not think that would have enough power to do so.
