No, passing tracks were never needed in Chicago. The first train would be an "A" train, and every other station is a "A" station, except major ones which are "A/B" stations. In Chicago this worked for years, until they deemed ridership was too low, and made all trains local.

How did that work out? Wouldn't one train be faster than the other though?

Back to the topic, three-track sections is a good idea, one for bypassing.

No 3rd or 4th track needed, as mentioned.

No. First train makes 'A' stops. Next train makes 'B' stops. Major stations are AB stops. Minor stations are A or B. If you are waiting at a B stop, an A train will pass and you have to wait for a B train. They don't go faster or slower than one another, they try to efficiently cover the stations.

But how do you get from an A stop to a B stop?

You had to transfer at an A/B stop.

Yeah, I see how that works - I thought (given that this was a discussion of expresses) that the trains did actually pass each other. That right there, though, is probably why it died - necessitating two transfers drops ridership right through the floor for a lot of those A/B stations' users.

I was at Sea-Tac International Airport (I was on my vacation to Oregon and California for 8 days) and saw the light rail construction process. It is looking good but the station at Sea-Tac International Airport didn't get started yet. I looked around for a bit, I didn't see anything that will connect the airport and station. Can anyone please show me the floorplan of light rail station linked to the airport? Thanks!

Don't know off had where to find renderings (scour the ST website), but I know the station will be behind the parking garage, and riders will take a sky bridge from the station, through the parking garage to the terminal.

Well, define "good idea". It would cost a lot and lose a lot of public support. In a lot of the places where light rail's being/been built, getting enough space for double track was hard enough - you'd have to destroy buildings in the Rainier Valley, add another $500m tunnel to Beacon Hill, move or eliminate the E-3 busway, possibly do major work to the bus tunnel downtown, totally redesign the elevated guideway...

It likely just plain wouldn't be cost-effective. This is light rail, not a heavy metro.

Actually, the airport station's foundation is complete, final approach columns are complete, and some of the structural supports are re-barred (what do you call that, anyway?) and ready for framing.

Here's a really cruddy, low-res site plan (north is to the right):

Thanks! I am little surprised because that airport station is little way off of the airport area. Good thing they will connected by skybridge.

It's all about the available space with this one. How the terminal roads and freeway is laid out. They're rebuilding the freeway access at the same time to accommodate the light rail as well as increase the capacity of the terminal loop road.

Yeah I saw that. The construction there was crazy.

I wonder if they will equip it with a special moving floor that speeds up people who can't walk fast or far to the terminal from the light rail station. That type of stuff is common in some airports around the US. I forget what it is called.

I don't know if anybody has linked to this document yet. It's a 28 page, full color outline of the ST2 plan.

http://www.soundtransit.org/Document...Plan_08_07.pdf

There's a few more publications on this page as well:
