On occasion, when I make a cross-lake journey using Sound Transit’s ST Express, I step upon a bus that’s packed tighter than a can of sardines. Today ended up being one of those days — even though my trip took place before rush hour. My suspicion is that the Blue Angels’ practice had something to do with it, because the squadron’s performance over Lake Washington caused Interstate 90 to be closed twice (once in the morning and once in the afternoon). This forced the rerouting of the 550 Express, which normally goes over I‑90.
I chose to wait until after I‑90 was reopened to go back across Lake Washington. But apparently many other people had the same idea, because the 550 I walked onto had barely any room. After the doors had closed, I turned to the person behind me (who had graciously made room for me) and said, I wish we had light rail running through this corridor.
“Oh, man,” he said. “That’s what we need!”
All the people around us nodded their agreement.
Another spoke up and lamented that East Link was still more than a decade away. “That might be true,” I replied, “but at least the project is moving forward.” I explained that just last Thursday, the Sound Transit Board had selected an alignment for East Link which Bellevue’s City Council could live with. Everybody who was following the conversation seemed very pleased to hear this.
Tim Eyman and Kemper Freeman can bluster all they want, but the reality is, the people of Puget Sound want this project. They voted for this project. And they expect Sound Transit to build what it promised.
The beauty of light rail is that it offers a faster, cleaner, more reliable commute. Light rail is something people know they can depend on. The service is frequent enough that you can ride without a schedule. Trains don’t have to dwell as long at stops as buses because people just walk on or off (no standing at the door waiting to pay your fare!) And you don’t have to worry about traffic, because light-rail runs in its own right-of-way.
People who have to cross Lake Washington on a regular basis (like me!) have been ready for East Link for a long time. We want it to come it online as soon as possible… and we wish that it already had.
And the really astounding part about East Link light rail is that according to Sound Transit in the Final Environmental Impact Statement, this cross-Lake train will add daily only about 10,000 new transit riders to the regional transit rider count in 2030, compared to not building it and sticking with express buses in the Center roadway.
That 10k increment covers the whole future line from Redmond Town Center to downtown Seattle, and takes into account the westside light rail line from Lynnwood to Highline Community College as a feeder to East Link.
10,000 new transit riders after billions spend. Why so few?
One “big” reason for only 10K additional riders, is the trains really can’t carry more.
If the system had been lower cost monorail, it could carry twice as many riders.
Light rail is actually a 200 year old technology. It has a top speed of 55, and averages about 35 mph on the Seattle to Airport run. A pull out at Seattle, will get a rider to the airport (14 miles) in about 25 minutes.
The light rail trains almost never get to 55mph, but rather hit top speeds of about 48 in a few small straight, elevated sections. It’s mostly a limitation of steel wheels on steel rails and turning radius. The train stays on the rails only from just gravity.
Monorails have top speeds about 95 mph, and average about 70 mph on most trips, whether that is Seattle, Tokyo, or Disneyland. Plus monorails are twice as long as a typical light rail car configurations.
Monorails use a bit more electricity, as tires on the track have more rolling resistance. However, electricity is the least of Sound Transits problems. Monorails have much shorter stopping distance in an emergency than light rail. Monorails almost never kill people on the tracks. Light rail systems kill people, with almost clockwork precision that can be planned as deaths per year for a system.
Consider 10,000 people per day, round trip. That means 5000 people toward Seattle in the morning, and 5000 leaving in the afternoon-evening. When broken down more, about 3700 people need a ride in a 2 hour window in the AM, and 3700 in a 2 hour window in the PM. The double light rails car configuration (two trains hooked together) is Sound Transits biggest possible configuration. In that mode, it will hold about 80% of a typical monorail train, or about 135 riders. At about 1800 riders per hour demand, and 7 minute minimum safety headways on the trains, the system can’t even move 1800 riders per hour in a given direction.
Look at this system. 1⁄3 third the time to build, and 1⁄5 the cost. And it moves more than twice the riders, at twice the speed, and more than twice the safety.
