I agree with Ben that it's from the Buffalo Rochester & Pittsburgh Railroad.
That would give it a date range of 1885-1932, so "1917" on the reverse may well be the year of issue.
My first thought was that it looks like a tool check or work check, rather than a baggage tag. However, given the fact that it's dated, it may be an annual rail pass— although the only pass I can find listed from that railroad is printed paper (1885).
