Thanks for Your Patience During the Rose Quarter MAX Improvements

Like we mentioned in our Rose Quarter Progress Report, the MAX improvements work this time around was much more complicated — and disruptive — than the First Avenue project from May.

Crews replaced and upgraded tracks, signals, switches and more around the Rose Quarter Transit Center.
Crews replaced and upgraded tracks, signals, switches and more around the Rose Quarter Transit Center.

Over the last two weeks, as we installed upgraded track, signals and switches near the Rose Quarter Transit Center, many riders became very familiar with the Lloyd Center–Rose Quarter shuttle buses. These were our best option for replacing the service between the three closed MAX stations, though they made for a disjointed commute.

Shuttle buses carried MAX riders between the Rose Quarter and Lloyd Center stations.
Shuttle buses carried MAX riders between the Rose Quarter and Lloyd Center stations, and between Kenton and Portland International Airport.

For others, the commute just became longer, as trains arrived less frequently (and more packed than usual). Finally, some chose to do something altogether different and took the bus, biked or shared a ride instead.

(We should also mention that the Kenton–PDX shuttle became an unexpected highlight of the project — thanks for all the positive feedback!)

In the end, nearly everyone had to plan for an altered commute.

Volunteer Ride Guides and Customer Service staff helped riders get around the Rose Quarter construction.

We asked a lot from you — more than ever — and throughout it all, your patience and understanding shone through. This attitude allowed us to focus on improving the 30-year-old trackway at the Rose Quarter safely and efficiently.

Here’s to you, and to a more reliable ride for decades to come!

The Plan For Rose Quarter

From Sunday, August 21, to Saturday, September 3, we’re making improvements near the Rose Quarter to improve MAX reliability and make for a smoother ride.

Much like the work we completed along 1st Avenue in May, we’ll be replacing switches and improving the tracks just east of the Rose Quarter MAX Station. Switches in this area are 30 years old, so crews will replace the wooden ties (which were standard back in 1985) underneath the switches with a concrete track structure and much more durable and robust materials.

We’ll also realign the section of track that runs westbound into the Rose Quarter MAX Station. We’ll begin by removing the rails and that run into the old Trolley Barn. Then, we’ll smooth out the curve into the north platform, which will create a smoother ride into the station. This new design will help eliminate some long-term maintenance challenges and reduce wear and tear on the tracks. As part of the realignment, crews will adjust the overhead wire and relocate two existing poles.

We’ll also be updating the antiquated MAX signal system in the Rose Quarter area. Signal technology has improved dramatically since these were installed back in 1986. This will be the first time in MAX’s history that we’re upgrading the original signals — it’s kind of like rewiring part of your house. We’re most excited for this upgrade because it will decrease the chances of a signal malfunction, which causes train delays.

All of these much-needed renovations are to improve MAX reliability and keep trains running on time, but this work will disrupt regular MAX service for two weeks as we’ll have to shut down service along Holladay Street between the Rose Quarter and the Lloyd Center/NE 11th Ave MAX Station.

We know this two-week disruption will be a hassle, but it’s all for a good cause — to create a better and smoother ride for you.

Minimizing Heat Delays on MAX

Last year, we shared a bit about why our trains slow down when it heats up — basically, temperatures above 90 degrees bring the possibility of rails expanding and kinking, or overhead wires sagging.

We know how it feels to slow down in extreme heat.
We know how it feels to slow down in extreme heat.

Before we go any further, we should answer a common question: Why didn’t we build track that can withstand higher temperatures? Surely, places like Phoenix don’t have this problem — right?

It’s true. Hotter places like Phoenix, which experience many 90+ degree days, don’t have this problem. But they do have trouble at the other end of the spectrum, when it’s cold out. This is because transit agencies build systems to work within the temperature range of their region, with the rails and overhead wire resting (neither expanded nor contracted) at the average temperature. For reference, the average temperature here is about 55 degrees, compared to 75 degrees in Phoenix.

Nobody wants a slower trip in extreme heat. You’ve got places to be, and we’re trying to stick to a schedule. That’s why we’re looking into ways to speed trains up when it’s hot out — we’ve already come across a simple solution that seems to work: track anchors. These were initially installed along the new Orange Line track for other reasons, but later we noticed that the rail here didn’t seem to affected by high temperatures.

So last spring, crews installed similar anchors to the rail ties of a segment of Red Line track that we knew to be especially prone to sun kinks. These have kept the rail in place, even on warm days (when rail temperatures can approach 20 to 30 degrees hotter than the air temperature). This simple step, which didn’t even require disrupting service, saved approximately 25 to 30 minutes of time throughout each service day, adding back over 150 hours of increased on-time performance over the course of a year.

There’s also the issue of overhead wire sagging in the heat and potentially damaging the pantograph (the arm that connects MAX to the wire) if it drops far enough. So we’re looking into ways to give the counterweights — which keep the wire taut — more room to move.

This summer has been curiously mild, but we’ll use the hot days ahead to gather more data on how these potential solutions hold up in real life. Eventually, when we’re confident that they’re worth the investment, we’ll implement these upgrades on a wider scale. And we’ll be able to keep moving, right through the heat.

Speeding up MAX reliability improvements

Throughout TriMet, we have been focused on improving MAX on-time performance (OTP) — our measure of reliable service — and doing it safely. Back in January, I shared our plans to improve. We’ve made some progress, and we hope it’s making a difference in your ride. MAX OTP improved from 75 percent last November to an average of just above 85 percent in June. We still have a ways to go, but we are on track and remain dedicated to achieving our long term goal of 90 percent.

The MAX system is very complex. Over the course of a day, it is in operation for about 22½ hours and provides more than 120,000 trips. It has many moving parts that include 145 vehicles, more than 130 miles of track and overhead wire, more than 250 track switches and nearly 200 rail operators. (And that doesn’t include the many mechanics, cleaners, rail controllers, yard workers, engineers, field operations staff and others who keep our system running safely every day.) There are many events that can cause delays to the system — here’s an update on how we are addressing some of them.

Starting on time, staying on time

To get you where you need to go on time, our trains need to start their day on time. We have improved how we track which trains are ready for service, along with how that is communicated between our maintenance and operations departments. Using the new web-based system speeds up that communication and gives us more time to focus on getting vehicles ready for service safely.

rq (2 of 8)

Our managers, operators and maintenance teams also are working to ensure that our maintenance and operational checks are completed safely and in a timely manner, so our trains depart from the rail yard on schedule. But that’s just the beginning. To stay on time, we’re adding a portable data display to trains that will provide our operators with the current time and the time their train is scheduled to be at the next few stops. These mobile tablets are like the mobile data terminals on our buses that provide operators with key information, such as the time points for where they should be on their routes. I’d like to note that these are important tools to help our rail operators do their jobs, and operators will be instructed on how to use them while safely operating the train.

Uncovering common culprits

We’ve struggled with debris building up in switches, rail joint and track boxes on the Steel Bridge. This has given false indications that the track way on the bridge is occupied when it is not, leading to some significant train delays. The area of issue was in a section of the embedded track where all the MAX lines converge on the west end of the bridge. Crews have now removed the concrete around the track, which has improved drainage and gives our staff better access to keeping debris out of that equipment and also trouble-shooting any electrical issues which can rise from time to time.

Improving the tracks

Our maintenance of way department has been hard at work tackling several track projects. Some have temporarily disrupted MAX service; some have not. On the Red Line, near the Mt Hood Ave Station, crews worked overnight during non-service hours several days in a row last spring, installing anchors to the rail ties. In extreme heat, rails — which are made of steel — can expand and kink, requiring trains to run slower through the area. The new rail ties keep the rail in place. This summer we have experienced several warm days above 80 degrees, where rail temperatures can approach 20 to 30 degrees hotter than the ambient temperatures — so far we have not had any rail movement. This saves approximately 25 to 30 minutes of time throughout each service day, adding back over 150 hours of increased on-time performance over a one-year period.

During our 1st Avenue MAX Improvements project in May, crews installed new switches and rail and improved the track bed. This disrupted MAX service on 1st Avenue for two weeks, but it has paid off with the removal of slow orders along that stretch of rail.

Now we have another big project approaching fast: From Aug. 21 through Sept. 3, the Rose Quarter MAX Improvements project will replace switches just east of the Rose Quarter MAX Station and redesign the trackway, which will create a smoother ride. We will also upgrade the signal system, which will keep trains running on schedule into and out of the station. Like the work on 1st Avenue, this will require a major disruption to MAX service. Once again, we are asking for your help by adjusting trips to avoid the rush hours, using bus service or other transportation options. Learn more at trimet.org/rosequarter

Thank you for your patience as we continue our work to increase MAX on-time performance. We have much more to do, but we appreciate you staying with us as we keep MAX moving.

Renewing our bus fleet

If you ride often, you know we have some old buses. The kind that make you feel like you’ve time-traveled to 1995, when multi-colored cloth patterns were kinda cool, the Blazers played in Memorial Coliseum and Portland’s own Everclear released “Santa Monica” to the world.

That era is fading away, however, as we’ve put 326 new buses on the road the past four years. All of our new buses have amenities such as vinyl seats, easy-to-read LED signs, better interior and exterior lighting and onboard GPS (which improves the accuracy of our TransitTracker) — features lacking in some of our older buses. And our entire active fleet now has essentials like air conditioning and low floors for easy boarding. (We’ll keep some of the older buses as backup.)

This past February, the first batch of 77 new diesel-powered buses (the 3500 series) took to the streets. By the end of the month, they’ll all be in service.

Our buses are getting more efficient in fuel consumption and emissions, led by eight hybrid buses, four of which have all-electric capabilities. We’ve also tested some fully electric buses, technology that’s quickly advancing and certainly something we’re considering for the future.

And we’re not finished. (Not even close.)

We’re getting 151 new buses in the next three years, which will help keep the average age of our fleet to an industry-standard eight years. This way, your next ride is less likely to remind you of the time before flip phones.

Line 97 will connect Tualatin and Sherwood!

Our friends in Tualatin and Sherwood have no excuse NOT to get together more often. On June 6, we’ll unveil our newest bus service — Line 97-Tualatin-Sherwood Rd — the first direct transit connection between the two towns. All aboard!

Line 97 will help connect people to jobs, shopping, services and more in these two growing communities. It also provides an alternative to driving and will ease congestion along the Tualatin-Sherwood corridor.

5-31-16 Line 97 (3 of 4)
Line 97-Tualatin-Sherwood is our newest bus line and the first direct transit connection between Tualatin and Sherwood.

The nine-mile round-trip journey will run every 30 minutes during weekday commuting hours. The bus’ first stop of the day is Tualatin’s WES Commuter Rail station at 6:20 a.m. It will then travel through downtown Tualatin, past industrial areas, the Sherwood Market Center, Sherwood Plaza and the new Parkway Village before making a return trip.

Line 97 will also connect you to other TriMet service. In addition to WES, you can link up with other bus lines such as Line 76-Beaverton/Tualatin, which serves Tigard and Beaverton, as well as Line 96-Tualatin/I-5, which goes into Downtown Portland or south to Commerce Circle in Wilsonville. Near the Sherwood Plaza stop, you can also transfer to Line 93-Tigard/Sherwood or Line 94-Pacific Hwy/Sherwood.

5-31-16 Line 97 (4 of 4)
This new bus service runs every 30 minutes during the weekday commuting hours and between the Tualatin WES Station and the Sherwood Plaza.

This is just the beginning of expanded service in this area. In the future, we plan to extend Line 97 to Bridgeport Village, the 72nd Avenue employment area, the Tigard Triangle and into downtown Tigard.

We’re thrilled to bring this new service to these communities. It’s a big part of our goal to bring more buses and trains — and better overall service — to Washington, Clackamas and Multnomah counties.

Thanks for Your Patience During the First Avenue MAX Improvements

Asking you to avoid MAX for two weeks wasn’t easy. More than 100,000 rides are taken on a typical day — that’s a lot of people we hoped would consider taking the bus, biking, carpooling or working from home instead.

It’s the kind of thing we’d only do if we really had to — and for First Avenue, this was the case. We needed to replace critical sections of track and switches that had been in service since MAX opened in 1986, and the best way to do it was all at once. Unfortunately, that meant trains would have to be detoured around the project, adding pressure on everyone. Beyond the construction itself, we needed to communicate some complicated service messages to riders; in turn, many of you had to alter your commute and plan extra time.

We asked a lot but what you showed us was even more. The patience and cooperation you displayed was truly remarkable and deeply appreciated, and helped make a daunting project go even smoother than we hoped. Now we’re back and we’re better, and on track toward providing more reliable service.
