Ah-yep - that's the one.
I had forgotten that your original was vertical (aka "portait"), and I had to add a lot of 'mysterious' black to both sides so that it would fit the horizontal (aka "landscape") format of the Screen Saver, in order to avoid just adding a 50% gray area to each side to build it up to 1600x1200 pixels. IIRC, stretching the shining rails a lot farther into the bottom of the picture than on the original took way more than one try - several hours over a day or two. Artistic license, or whatever ... A truly collaborative effort, of which the purists would probably NEVER approve since 25% of either side and 15% of the bottom is about as real as the oliphaunts in "Return of the King".
If you are using my much-modified version on your "Narrow Gauge Memories" page, I am truly flattered!
THANK YOU, and Merry Christmas!!

p.s. Your enhancement to the sky is definitely an improvement, and since you have posted the picture then there's no reason for me to do so.
