An easy fix to put in a gap after the track is down is to use your Dremel to cut a gap in the rail an inch or less passed the frog, and then use a piece of styrene with acc to fill the gap, and keep it from closing up. After the acc sets up, you can cut the styrene close to the rail on top and both sides with a sprue cutter or rail nipper, and then use riffler files to shape the plastic to match the rail profile. A free source of styrene that is perfect for this sort of thing is to recycle the bread clips that hold the bags closed on loaves of bread. Once the styrene is filed to match the rail profile, it disappears from sight unless you look really close for it. Don't use files on top of the rails, though. Just use and Exacto knife to carve the styrene flush with the top of the rail, so you don't put scratches in the rail to attract dirt.
