As to railroad operations with these tank cars ... I'm not quite sure if these cars were loaded from a team track or spotted on a siding so they could be loaded by several tank trucks, and later being picked up by the local milk train and hauled to the processing plant.
Thanks trumptrain. Page 21 of the Dispatch link in the first post had an operations section that at first surprised me but then made sense: it says that at a station, the road engine and milk cars would uncouple from the passenger train, swicth tracks and back into the local milk plant so the milk could be pumped in. The train would then be remade for its next stop. No switcher needed. The next page talks about city dairies, which didn't have sidings, so milk cars were spotted on tracks and the milk transferred to tank trucks.
