Saving Engines

[NW Mailing List]

Very interesting!  I'm surprised by the light weight of the boiler &  
firebox (adding in the weight of the flues) relative to the all-up  
engine weight.

I've often wondered how loco designers estimated the weight of new  
loco designs.  We all know that they didn't always get it right: vis  
the C&O H8s!
