Nice selection of freight cars with the exception of one. I do not recall Mopac having that newer design gondola as they bought several thousand which had waffle designs in the panel not smooth. The other cars truly exist or have since been retired from regular service. I used to see the St Regis car come through on the Milwaukee Road from Idaho. Weyerhaeuser had a distribution center here on the CNW so they were regular fixtures and those loaded in Washington State where their HQ should still be. The side door was divided into three pieces and all three were movable you just had to push them to whatever angle you wanted them at Some Eastern museums have them as donations from the Cooperstown and Charlotte Valley RR and up in the Twin Cities Progressive rail has a few for maintenance of way duty that were former Minneapolis Northfield and Southern. Also the mini hi Cube CB&Q boxcar was somewhat known for paper and cardboard rolls but the majority of the ones built in the late sixties we're actually for hauling appliances washers dryers ovens and dishwashers and a big loading point was Louisville KY even Milwaukee had some at Hotpoint the rest are pretty self-explanatory glad you got a good deal on them
