When is the best time to catch it working the Cragin Line down to Alpha Baking? I was over there last month but no trains were in the area. I saw several covered hoppers on different tracks. Does Alpha have its own TrackMobile type device to spot them, or does UP come down and switch the cars in and out as necessary? I didn't see any place where a car mover like a TrackMobile could be stored plus it's a sharp rise up from ground level.
