MUNI Twin Peaks Tunnel Delays

On Wednesday around 7pm I hopped on board a westbound L Travel MUNI tram to get out to the ocean and watch the sun set over the Pacific. Well after departing Castro station, on what should be the fastest part of the line, my LRV proceeded at a rather leisurely pace through the Twin Peaks Tunnel (30mph instead of the 55 or so in the Market St tunnel) and then, just before the Forest Hills station, came to a near complete stop due to congestion ahead. We then spent about 20-25 minutes crawling through the remainder of the TPT to the West Portal Station.

The last time I had ridden this route I had experienced similar delays in the TPT and I was wondering if this sort of thing is considered to be standard operating procedure. I did not see any sort of advanced traffic control devices at the West Portal grand junction so if this is a recurring problem why has nothing been done to solve it. Also, speeds in the TPT are also slow even in the absence of congestion in both directions. The TPT is straight as an arrow and should be able to support the same high speed running as the Market St tunnel. Can anyone explain either of these phenomena.

They've had a few collisions in there, so ...

Bummer. Next time, try the N-Judah, goes (close) to the beach as well, and no Twin Peaks action (Sunset Tunnel doesn't have as many issues, AFAIK, and only the N runs there, as compared to the TPT which has K/L/M)

The N was having power problems and was being bustituted.

The TPT is ATO just like the market st tunnel.

Welcome to Muni -- discouraging transit use on a daily basis. Your delay did not register in the Muni report for Wed.

IINM there has been recent talk locally about track issues which would generate slow orders.

That too would make sense. I hear from a bud out there that they've had a few close calls as well (brake issues I guess) and even where the rails are good, you want to take your time through there ...

Well it could have been scheduled. I had only looked at the N timetable in advance. Luckily I got to the beach with about 3 or 4 minutes to spare although I had planned about 20.

Speeds in the Market St Tunnel were still high. Why would trains need to go slow in one but not the other?

I was referring to the publicly distributed Daily Reports which allege to list delays >20' In recent years the reports have carried less and less useful data. www.sfmta.com/cms/rdlymuni/dlymuniindx.php
if you care to have a look
