About car weight

[P5se Camelback]

At the risk of sounding trite, I will state the NMRA RP-20.1 Car Weight figures here. The RP is a Recommended Practice and does NOT carry the same responsibilities as a Standard. Now, that said, it is a very good recommendation for good operation.
...
SCALE INITIAL WEIGHT + ADDITIONAL WEIGHT per inch of car body length
This means that:
HO = 1 ounce + 1/2 ounces per inch of car.

In other words a 6 inch car should weigh about 4 ounces.

That's all folks. :-)

I totally agree with Roger. You never know when one of your pieces of rolling stock might spend an evening visiting the layout of a friend, and If your friend is like my friends up in Pennsylvania used to be, the car had to go through a check list before hitting the rails ... coupler height, wheel gauge, weight, etc. ... all the NMRA Standards and many of the RP's.

To me, it just makes good sense and helps eliminate one more cause of frustrating derailments.
