MisterBeasley Is this a model of one of the actual prototype cars used for calibrating real world scales, or are you actually calibrating model scales with it?

No... no scales in my future. :-)

My two are brass that I weighted to about 2 3/4 oz. I also modifiied the side frame mounting to equalize the wheels. I can shove 20 cars uphill with them through curved switches with no derailments.Not how they are usually handled on the prototype but I wanted them to run reliably.

I've scratchbuilt 5 or 6 scale-test cars, but the two that I've not given away are 2" long, with this one weighing-in at 2oz....
...and this slightly-different-style one at 1.75oz.
I'm pretty sure that the others are all around the same weight, too.
Mine always travel at the rear of the train, and I sometimes use that as a deliberate operational impediment when the train in question needs to "switch" the industries in the towns through which it passes...lots of setting-outs and run-around moves necessary.

I would say pack as much weight into the cavity that will fit. I used a "liquid gravity" weight product that is tiny steel shot.

The NMRA R.P. begins with a 1 oz. HO baseline and a half ounce per inch so a 2" car "should" be 1.5 oz. Commonly, the scale test car would be carried behind the caboose. They had trainlines but no air brakes.

Hi all.
Another question if I may. I bought an HO scale test car and I was wondering how much it should weigh. There was a discussion a while back on the weights of cars but the test car wasn't mentioned.
Not a big issue... just wondering.
Thanks for any wisdom!!
