Help with official GLC designations

Unread postby Todd_F » Sun Oct 06, 2019 7:04 am

Hi all!
I’m working on a systemwide GLC video and wondered if anyone could help identify each portion of the line, or branch, as they are referred to today? I use terms like “Middleton Branch”, “Oakley Branch”, “Yuma Line”, etc but I don’t actually know if any of these are official GLC designations.

Thank you for any assistance, insight, or clarity you can offer!!

When finished, I’ll be sure to share the video link.

AA-OWO = AA District
OWO-CAD = Clare District
North of CAD = Northern District (Petoskey and Traverse City respectively)
OAK, MID and YUM are all branches.

I'm guessing at the names to see how close I can get :) .

Thanks for the great info! I didn’t realize the Cadillac District began at Owosso. I always thought Clare separated districts—probably because of how I’ve seen the Caddy/Owosso trains function. It’s good to know why I was wrong.

Does the Grawn Branch have a name or is that part of the TC District?
I’m assuming the TC District starts at Walton Jct.

Based on the mile posts I think the answer to both of your questions is yes (Grawn is part of TC District)

AARR, thanks. I never saw mileposts in the grawn line when I was there so I wasn’t sure, but it made sense.

Am I correct to assume the St Charles District is the Oakley Branch?

You are correct, Todd :)

However, I didn't think the tracks were in place past Chesaning anymore :?

Unknown District 225.9 - 226.3

Have heard this called the BELT LINE before. Section between Selma and Tufford yards.

I’ve also heard Cadillac crews refer to that as the Belt Line. It makes sense. :-)

The belt line is the track that rune SW - NE between Selma yard and the PRR enginehouse area

I reviewed a Conrail track chart for the Ann Arbor. The mileposts listed above correlate to where the yard limit sign was located just east of Whaley street to a point that shows a spur (maybe). It does not make sense that there would be a district 4 tenths of a mile long. Where did the list of districts come from?
