"Welcome home".
I think the line outside of the Airforce base is doing it's short excursions again.
Greenfield Villiage/Henry Ford Museum has greatly improved for RR content inside and out, over the more recent years. (With all that maize &blue, you kinda gotta know where that is 
)
During the winter the CN & CP holiday trains have both made passes by us and unscheduled stops Downriver (depending on if they are on time for Ill. or Ind. I think)
Owosso still has things going. I think that would be the largest.
But thats all I know of. I.e., not much for the big names and big modern locos around metro that I've ever heard of.
There is one railfan site frequented by some Detroiters that is pretty savy on the sweet spots but I can't recall the name right now.....I was thinking about them a lot lately. Give me time and wish real hard for some faster replies, lol. I don't get out much so don't give up hope. I'd bet Detroit Model Railroad Club and the 3railers are your best bets for more info outside of your asking here.
