IMHO - Just leave the lens set to infinity at F16 and
point and shoot when the train fills a satisfactory
area in your view screen. (Remember that it is closer
than it appears!) Everything will be in focus from
about 5.5 feet onward to infinity. ("To Infinity &
Beyond!" --Buzz Lightyear)
Oh, and remember to jump OFF the tracks (preferably
WITH your equipment) after releasing the shutter.
