These cars out of the box are toys with potential. Plano is coming out with a roof walk and up grade parts. I dug this 22 year old project out of my junk box and went full bore. Deconstruction requires several hours of work that's not much fun! I replaced the end platforms, removed the bottom horizontal rib so I could thin out the top one. There's a space between the ribs on the prototype, with step I created a space. The hopper bottoms required lots of work that I'm doing now. The side vertical ribs were to small, so I'm replacing them with .060 half round styrene. It'll have sergeant couplers and 125 T trucks. I'll add updates as I go.
