Why would replacing a 2 axle trailing truck on a 4-8-4 with a 3 axle trailing 
truck be better for light rail & light bridges branch lines? Yes it would 
lighten the weight on each trailing truck axle but on the 2 axle trailing truck 
was the weight on each trailing truck axle MORE than the weight on each driving 
axle? I doubt it. So what is the advantage of a 3 axle trailing truck. In fact 
the weight of the bigger trailing truck frame and its extra axle and wheels 
would ADD to the weight on the trailing truck. What am I missing?
