Remember, standing-room-only #1 buses go through this corridor right now, as bad as that service is, every 10 minutes or so during the rush hour. Add some passengers who don't take the bus now and you've quickly overwhelmed a 15-minute rail headway service, for instance. Below 15 minute headways, singletrack on Guadalupe is not going to work.
On the original TWG proposal to go out to Mueller via Manor Road, I suggested doing singletrack on Manor, so I'm not against singletrack everywhere, but that was more of a streetcar proposal, and Manor isn't the key activity area where every bit of headway counts.
The only singletrack-like proposal on Guadalupe that ever got any traction was the 2003-2004 timeframe effort from UT to (as SAM pointed out way back when) provide a one-way loop around campus - one direction going down Guadalupe and the other one going up San Jacinto, joining up at MLK and Dean Keeton. Problem is that still had two tracks in the most constrained part of Guadalupe (27th - 29th). This wasn't an effort to disrupt Guadalupe less, in other words, it was an effort to play along with the University's ridiculous claim that San Jacinto was the new center of campus activity.

Hey M1ek, appreciate the informative response and absolutely get the importance of short headways especially there. That stretch of Guadalupe that I was suggesting for single track isn't all that long. Is there a way to interlace a double track section so that trains could pass each in the middle somewhere to get 10 minute headways. Just wondering if this might be a less-than-ideal-but-still-pretty-damn-good solution.
Or perhaps I'm just completely mistaken on what the push for not putting the rail on Guadalupe is coming from. Is this about something other than the constrained width of the ROW in that area?
