Anything pertaining to railfanning in Michigan.
According to the NS train symbols page on RailroadfanWiki, there is a new symbol that goes to Detroit, NS 29M. It originates in Avondale Yard in Kansas City, MO, and terminates in Oakwood Yard in Melvindale, MI. It also works several places as well. Please let me know if you have any further information on the symbol. Thanks.
