- May 3, 2008Alan--
It's true that *some* commercial rail cleaning cars can be effective;
I wasn't going to go into detail as to which ones. The point was that
many of them aren't, particulary the ones with rollers.
Actually, what I've found to work best is the old Masonite block
under the boxcar trick. Cut a rectangle of Masonite to the width of
the track ties, and a length that fits between the trucks of a
boxcar. Orient it with the softer, irregular side facing down, and
expoxy the heads of two small brads to the smooth, hard side. Drill
two holes in the boxcar underbody to align with the nails. Place the
nails into the holes under the car, put it on the track, and drag it
around in a train. It's amazing the gunk these things pick up.
