About 4 to 6 oz.
The NMRA Recommended Practice (RP) is 5oz plus 1oz per inch of length.

The NMRA recommendation works out to 15 ounces for a 40 foot O scale car. That is a good guideline. I like 40 foot cars that are about 2 ounces heavier than the guideline or 17 ounces. MTH is very consistent about weighting their 40 foot box cars and reefers to that weight. Atlas tends to be 3 or 4 ounces heavier than the guideline with many of their cars. That works out fine unless you have big trains and all Atlas cars or mostly Atlas cars with a few Weaver lightweights at the head end.
This seems like a lot of weight I will probably go lighter. Now how do I get those tank car's apart to get inside. Weaver cars a fragile.
