Painted Rod Bearings(?)

S SJCOGR Forum Member

I had the pleasure to run trains with the National Capital Trackers today on the turntable of the B&O Museum. As I walked around the museum, I came to their latest restoration, the AJ Cromwell a 2-8-0 that was just unveiled a few months ago after restoration from the 2003 roof collapse. 

 

With the restoration very accurate historically, I noted the rods (bearings perhaps?) had portions painted silver (see attached photo). I couldn't help but wonder why. Is there a practical reason such as making cracks more obvious? Just for looks? 

 

Many thanks!

Don't know about rules & regulations from back in the 1800s, but "painting" of rods & couplers was against the ICC rules in the 1900s. The use of white wash, in order to detect cracks in rods, drawbars, etc. was standard practice. The UP, for example, used "bright aluminum" on journal covers in order to detect leaks, was standard practice starting in the late 1940s/early 1950s.
