A very informative read on "Light" locomotives with ordering information.
The references beginning on Pg. 38 are of particular interest. Curves, grades, clearances and fuel are worth a look. Including a handy chart to determine the degree of curvature using a thirty-foot piece of string!

Also look at the formulas for determining Tractive Power, Train Resistance and Rail Capacity. Interesting information and—frequently—the subject of some questions posted in these forums.

Thanks for posting, what do they mean the front trucks are "equalized" with the front driver? Or perhaps my question really is how do they do that?

Hi, Henry
Equalized—in locomotive suspension—refers to the weight being distributed over more than one wheel or journal or bearing box, by a series of pivots, arms and links connecting the spring rigging so that better contact with the rail can be achieved.
I'll post a diagram when I get a chance since it is easier to show than to try to describe.
Thanks, Ed
That picture makes sense, thanks Ed.
