Cut and cover is the chaper option but don't try it. It just creates a huge mess, especially since the LRT extension goes through some arterials of Bellevue.

Just look north to the border and see our mistakes.

The stub tunnel in Downtown Seattle was excavated using cut & cover.

Zap Gridlock joins the party

I didn't know Sound Transit had a mascot, looks like some kind of odd superhero.

I'd have thought the network's having more stations than that shown in the thread author's map (back at the beginning) -- it used to take just as long to drive across that city as it did crossing Toronto, hours 'n hours....

For the Americans, look up Brian Mulroney if you're interested. Zap does bare a striking resemblance to the former Prime Minister for sure.

Second, most of the crews are salaried, as I understand it. They have a minimum shift length, so increasing the length of time they work in a shift wouldn't increase labor costs.

Third, when there are only a few trips, people are less likely to use a service. They worry that they might get stuck at work late, or they want the option to go home at midday if they aren't feeling well - there are myriad reasons that people look for flexibility in timing. The more trains that run, the more people will ride *all* trips - not just the new trips. Only two round trips are packed to the gills so far - of nine total (six Tacoma, three Everett). This is the reason Sounder per-trip expenses are so high right now are that the Everett service is fledgling. We've run two round trips a day with service to only two non-Seattle stations. That's not high enough for people to want to use the Everett service - we've just implemented trip three, and haven't even started running trip four. When the fourth trip starts running, and the second Everett parking facility, Mukilteo station and ferry terminal, and Edmonds multimodal terminal are complete, you'll likely see Sounder North ridership go up. I'm betting it'll quadruple or more.

There's also the efficiency factor for maintaining each facility. Spreading O&M costs across more riders decreases overall cost per rider for these fixed costs.
Giving credence to UrbanBen's arguments here, Sound Transit's latest quarterly ridership numbers came out and though the boardings per trip on Sounder South are down (because they added two round trips since last year -- overall, ridership is way up), the cost per boarding also came down. In other words, an awful lot of the costs are fixed -- running an extra train, even with fewer riders than the packed ones, actually increases efficiency (at least in this case -- presumably totally empty trains would not increase efficiency).

Thanks. Also, you just wait. Late this year we should be adding a couple more runs to Sounder South, and Mukilteo is opening at the end of May. By this time next year, we'll see cost per boarding drop by another 20%.

The vote this year will likely offer major service increases to Sounder South, as well as longer trains to handle the load as it increases.

They just laid the final track earlier that week. It's a continous 14 miles of track and on budget and on schedule to open in 2009.



You can notice 2 golden bolts on the track.

Real gold? or just paint?

I read somewhere that central link is 90% done. is it possible that light rail might open earlier than expected?

It's at least 90 percent done. Who knows if it opens earlier than it was scheduled, but otherwise it'll probably open on June 2009. The bolts aren't real gold, lol. Real gold is too soft.

Paint for sure on those bolts. It doesn't look to be the right color, not to mention the malleability mentioned above.

Everything talking about light rail coming out of ST has always mentioned on schedule for June 2009 for Downtown to Tukwilla, and Dec 2009 for the Airport extension.

Sound Transit says "summer": http://www.soundtransit.org/x1171.xml

They slipped from June to July due to the tunneling contractor, who ate all of their float time (six months) and any chance of opening early.

Airport will be December - but probably December 31st!

Is there any chance they could get the system open earlier but defer opening Beacon Hill station? Or are we really waiting for the tunnel itself to be done?

The tunnel is actually done now - it's the systems and communication work that was delayed by the late opening of the tunnel. There's not really anything we can do.

Sound Transit actually pushed its first train through the tunnel, all the way to the Tukwila International station on June 14th. They will begin testing the trains to run on their own power later this summer on that segment.

Photo of the Week

June 27 - July 4, 2008



Light rail in the Downtown Seattle Transit Tunnel

This Link light rail train recently joined buses in a successful test of the Downtown Seattle Transit Tunnelís signal system. It was the first time ever that trains and buses ran together in the tunnel. The test took place in the evening, when the tunnel was closed. When light rail begins service next summer, trains and buses will both run in the downtown tunnel.

Photo of the Week

June 20 - 27, 2008



In the Beacon Hill Tunnel

For the first time on Saturday, June 14, a Link light rail car rolled down the tracks through the Beacon Hill Tunnel. The light rail car was pushed by a special truck through the Beacon Hill Tunnel, the Rainier Valley, over bridges spanning I-5 and the Duwamish River and then all the way to the Tukwila International Blvd Station, a distance of about 11 miles. The test of the light rail car, tracks and light rail stations went very well.
