Re: Scale Weights

So basically all model cars should weigh about the same according to length? That's why a 40 ft flatcar would weigh the same as a 40 ft boxcar? Maybe THAT's the reason that one wood, kit-built boxcar

Re: Corner Grabs for Running Boards

The corner grabs I have are made by Tichy. I don't recall if they are equal leg or not. So I can't say whether they are the same as either of those you have. They are made from a hard copper .010

Corner Grabs for Running Boards

Sometime ago I purchased several packages of corner grabs for running boards. There were two styles of grabs. in one of the packages the legs on the corner grabs were equal in length. The other

Re: Tony Thompson & Scale Weights

Only if you want to model empty cars! Then, as pointed out in another post, mixing widely differing car weights causes problems on the real RR, and with our exagerated curves and grades, these are

Don't forget that you will have to think on the locomotive drawbar pulling power also. Precision scale and Intermountain makes wheel sets with ball bearings and don't forget to replace the coil

Re: Scale Weights

Paul, model trains do not perform like real trains. For one example, the weight of the car on the rail is distributed over an area larger by a factor of 87.1. (The surface area of contact between the

Re: Tony Thompson & Scale Weights

Tony, HUM!!!??? That just brought up another interesting thought to me. Wouldn't it be more true to scale-weight then, to know the prototype-car's empty weight, divide that by the cube of 87.1, (or

Tony & Tim, OK, thanks. I see where I erred, in scaling down only 1 dimension of a 3 dimensional object. Paul Hillman

Great coal data, Tim! Why was so little anthracite used in the midwest, compared to NY/NJ/PA? I thought that people really liked burning that sort of coal in their furnaces. Were there sources of

Re: Tony Thompson & Scale Weights

Paul, objects have 3 dimensions, so 87.1 x 87.1 x 87.1 equals (approx) 660776, so a 200,000 lb loaded prototype car in should weigh 4.84 ounces in HO scale. The NMRA recommendations are in that
