These loads are very nice, a bit pricey if you a doing a whole train set though. They fit their respective cars w/o any problems. I have 2 scrap metal loads for my MT gondolas, 2 sand loads for MT 33' hoppers, 4 ballast loads for Walthers ballast hoppers and 27(so far)coal loads for my LBF Coalporters. They do look so muc nicer than the loads that come with the coalporters.
