Anyone knows? Any historicaly significant lines were built in that time? And is it from a light rail or what kind? Thanks!!

Look up rail profiles on google. Guessing it would be in the 70-80 pound range. Pretty common all over the US back in the day.

Thanks for your reply. I heard there was a Krupp rail manufactured in 1881 that was removed from Santa Fe trackage, approaching the old Ferry landing, along Pacific Highway, in Downtown San Diego.
In the 1920s a lot of Krupp rail. But dated later. And my sizes indicate either 50 or 55 lb rail, not usually used even that time for main line heavy duty routes. So I'm a bit confused here.

Krupp of Germany was a (the?) major manufacturer of steel back in the late 19th-early 20th century.
