Peter's Model Railroading | The Equipment | Box Cars | SAL B7
Construction: Weight

The last thing I attached was the brake wheel, following the instructions. I then put the underframe with the wheels, the couplers, and the body on a scale and they weighed 5.9oz (166g). A car this size in S-scale should weigh 5.75oz, so it is perfect. However, I will add some stick-on weights to the underframe, because the body is kind of top-heavy, so I want to avoid any rocking that might happen when the car rolls down the track.
