In a totally different direction. I decided to take some 40 trailers apart (most glued, some not), and remove the weights, I installed when all I had was plastic 89' piggyback flats. Now that I got just a soookin deal on a bunch of BLMA and other metal 89' flats, it was like insult to injury to have the trailers weighted. It actually made the train a lot harder to pull, needlessly, turns out. I removed almost 2 lbs of weights. Now them 4 geeps will rocket up the grades huh?
