Solid Bearings vs. Roller Bearings

gary laakso

The industry had long time experience with roller bearings applied to passenger cars, both heavy weight and light weight and steam locomotives.  Great Northern, a paragon of thrift, started installing roller bearings on its 1937 Empire Builder and even started adding them to steam locomotives by 1940.  I wonder how much unit prices fell so that GN added them to its express boxcars?   GN waited until 1948 before ordering those newfangled all steel boxcars.
