I was humming the folksong "I've Been Working on the Railroad" when I hit this phrase… What's its origin?
I feel that livelong establishes that the day may feel like an eternity. But I noticed that the adjective doesn't seem to be used in positive circumstances. That makes my ear want to supplant it with goddamn: I've been working on the railroad, all the goddamn day. Is there any truth here?

All the livelong day: the expression is actually generally used with a negative connotation, to refer to a period of time that is too long, too tiring:

According to the Phrase Finder the folksong "I've Been Working on the Railroad"(1936) you cite may be responsible for its origin, but the expression was actually used well before that date and the term 'livelong' has a complex and ancient origin.
The following source says that the origin of the adjective"lifelong" is quite old and it originally meant, "dear, beloved". Only in the late 18th century its meaning changes to "lifetime, lifelong" probably as a result of a misanalysys of the word's origin:

Ngram, all the livelong day can be found from the late 18th century.
