Alignment schematics

Whoever you are that keeps doing websearches like these that land you on MAX FAQs…

…this post is for you.

A while back, someone over at Portland Transport jumped through the mired swamp that is TriMet’s public records request process and came out with an extremely detailed schematic of the existing and planned MAX alignment. Sample pages below:

It’s a very thorough document that has grade/elevation/direction changes, speeds, etc (though for the person who is looking for the deepest part of the tunnel, it appears to only give elevation above sea level, not depth below the surface, and paradoxically Washington Park is the deepest underground platform and yet appears to have the highest elevation above sea level of all the platforms). This is not exactly light bathroom reading, but it’s an interesting reference for the transit wonks out there.

Anyway, have at it, folks. It’s a PDF, about 2.5 MB, and since it had already been released into the public, I figure it’s fair to repost it, especially if it saves someone money by not having to request it from TriMet again for when you just need to know how far apart the Old Town Chinatown and Rose Quarter platforms are (2700′, for the curious).

  1. Darn, I was hoping this would answer one of my orange line questions, how will the overhead line(and Max Trains) cross OPRR’s line on New Water St? Wouldn’t the overhead wire be to low for OPRR train clearance? Will there be a break/coast zone? I’ve yet to find the answer!
