I finally aquired one of those long steamers (A spectrum 2-8-0) that are recommended for finding all the trouble spots in your track work and boy did it do its job in a hurry! This thing would consistantly hop the rails on the same spot on the lower loop. When I first built it, I was kind of lazy and forced sectional track into places it didn't really want to go and ended up with a nasty kink. Said kink really limited what could be run down there. Well I finally decided I'd livid with it long enough and tore it out. Pictured is the piece of flex track I should have used the first time. Now I can run literally anything down there.
