5 tips for a happy—and safe—holiday season

Christina Hansen-Tuma

The holidays are a time of wonder and goodwill, and for the men and women of the Transit Police Division, a time to step up our patrols on the TriMet system. In an effort to keep the Grinch at bay, we need your help to make sure your belongings (and those holiday purchases) make it home with you.

So far this month, we’ve noticed a good thing—riders being more courteous to each other. This is something we hope to see year round! But please don’t get complacent—thieves will strike when you least expect it.

Here are the top five tips to make sure you have a happy and safe holiday season:

  1. Pay attention to your belongings.

Too often we see someone hang up their bike on MAX and then go sit down with their back to it. A thief could make off with your bike and you wouldn’t notice! So far, two-thirds of reported thefts this year were items left behind or lost and never turned in to Lost & Found, so please keep track of your things.

  1. Pay attention to your surroundings.

We can all get so caught up in our phones or devices that might not notice someone watching us. Look up every so often to see who is around you and trust your instincts. When you hear, “Doors are closing, please hang on,” on MAX, make sure to hang on to your phone and other items. Thieves often look for opportunities to snatch-and-run as vehicles are about to leave a stop.

  1. Don’t leave valuables in your car at Park & Rides.

Leaving items, especially valuables, in plain view in your parked car is an invitation to thieves. If you must leave packages or other things in your car, make sure they are out of sight or locked in a trunk. If a thief walks by and doesn’t see anything worth breaking a window for, they’ll likely move on.

  1. See something. Say something.

If you see something suspicious, please say something. Tell your operator or call 9-1-1 immediately—we’ll decide what’s important. You never know, your call could prevent a crime.

  1. Look and listen when crossing tracks and streets.

Please listen for approaching trains and look both ways when crossing tracks. Take your time and don’t run across—a few seconds could save your life.

All year round, Transit Police officers patrol the system, hopping on trains and buses, and interacting with riders at stations and transit centers. During the holidays, we increase our missions to keep those looking to spoil the season from targeting you and your stuff.

“Santa Bob” steps down from his sleigh

Roberta Altstadt

Our very own “Santa Bob” has delighted riders for nearly 30 years as he maneuvered his sleigh—er—bus through the streets of Hillsboro, Beaverton and Portland. But before this holiday season begins, Santa Bob, aka Bob Foster, will be turning in the reins of his Line 88 bus.

“Santa Bob” retires

After 34 years of operating a TriMet bus, Bob is retiring. A few years into his job behind the wheel, Bob, who resembles the jolly old elf, began moonlighting as Santa for TriMet employees and families across the Portland metro area. TriMet riders also enjoyed their brush with Santa!

“Sometimes kids will say to their parents, ‘Look it’s Santa!’” says Bob. “That’s a tremendous responsibility, because you’re a walking billboard.”

With Bob retiring, will this be the year without a TriMet Santa?!? Kids of all ages: never fear, it’s a TriMet “Santa Exchange”!

Santa Mark takes the reins!

Santa Bob is handing the reins of his 40-foot diesel powered “sleigh” to Santa Mark. Mark Larson has been a TriMet bus operator for 25 years. For the last two to three years, some riders on the lines 54 and 56 that travel through Beaverton, Tigard and Portland, have been doing a double-take due to Mark’s resemblance to St. Nick.

“I get quite a few comments ranging from, ‘You look like Santa,’ ‘Have you ever thought about playing Santa?’ ‘Mom, he looks like Santa! I told you he was real!'” says Mark.

What does it take to be a TriMet Santa?

Being a TriMet Santa takes driving skill, great customer service, a Santa-like appearance and a degree in SantaClausology. Both men have attended the International University of Santa Claus.  Santa Mark has his Bachelor of SantaClausology; Santa Bob has his Master of SantaClausology and is working on a Doctorate.

Santa Mark knows he has some big boots to fill.

“I never wanted to replace Santa Bob—in fact, you can’t replace him!” says Mark.  “As to taking over as TriMet’s Santa? All I can say is HO, HO. HO. Who needs a ride?”

Huh? What’s an “all-electric” hybrid?

Andrew Longeteig

Now on the streets—you might find yourself aboard one of our newest all-electric hybrids! This next-generation of hybrids is designed to be our most efficient for fuel and emissions.

Thanks to a $2.5 million federal grant, we were able to purchase four of these buses, which are similar to a Toyota Prius—just a smidge bigger. Here’s how they work: a diesel engine powers a generator, which starts the bus and electrifies the energy storage system. The electric-traction motor then turns the wheels.

spacer

It’s a hybrid—but electric!

“All-electric hybrid” may sound contradictory. These hybrids, though, are different and have even more awesome features than the last four we launched into service in 2012.

Everything on them can be electrically powered 100 percent—and for up to two miles! (Our older hybrids can’t do this because the diesel engine powers the hydraulic steering and air compressor.) If there’s not enough energy stored in the battery, the generator starts and uses the diesel engine, which also recharges the battery.

Another cool feature is what’s called Stop/Start Drive. As the bus slows to about 8 mph—and as long as the lithium-ion battery has enough juice—the engine shuts off and the battery takes over.

During shut-off, the bus’ accessories—such as the lights, air compressor, hydraulic steering and air conditioning—are battery-powered. As the bus leaves a stop and moves faster than 10 mph, the engine starts again.

These buses use regenerative braking, too. This means when the brakes are applied, kinetic energy is captured and can be used immediately or stored in the battery for later use. The batteries also provide acceleration power.

Good gas mileage, low emissions

We won’t know until they’ve been in service for a while, but we expect these new hybrids to get at least 6 miles per gallon … just like our other four hybrids. In comparison, our newer fleet of standard buses get between 4.5 and 5 miles per gallon. In a 50,000-mile stretch, our all-electric hybrids would use about 1,719 fewer gallons of fuel when compared to our standard diesel buses. At over 50,000 miles, this saves about $4,000 worth of fuel!

The diesel engines on our newest hybrids also run even cleaner, as they comply with 2013 EPA regulations as opposed to the less-strict standards from 2010.

We’re often asked about getting more hybrid, electric, biogas or compressed natural gas (CNG) buses. We’re considering all of these quickly-evolving technologies, but as we test them, we look for cost-effectiveness of a bus’ entire lifecycle before making wholesale changes to the fleet.

Shhhhh …

And they’re quieter than our other buses. They’ll still make some noise, but we’ve never put a bus on the streets that’s basically as loud as a typical passenger car. Folks who are visually impaired will still be able to hear it.

Down the road

We’ll watch how our newest hybrid buses perform on the streets to see if we’ll buy more of them. Battery technology continues to improve and buses are being tested that can go 200 to 300 miles (wow!) without a recharge. These hybrids just may be great transition toward all-electric buses in the future.

Sign of the times: Older MAX destination signs going digital

Andrew Longeteig

The iconic MAX destination signs on our “old” trains—those made between 1983 and 2003—are going digital.

We’re phasing out the older signs as we replace the communications systems on 105 train cars. Yes, this includes the old-school roll signs that have to be hand-cranked by our MAX operators (a time-consuming task).

Since last year, we’ve been installing LED destination signs on the front, side, interior and back of these trains so you can more clearly see—even on those dark, dreary December days—where your train’s headed. We’re also upgrading the speaker systems so you can hear us better and be able to listen to any special recorded announcements.

Doug Jones is a TriMet engineer working on the project. He says with the opening of the new MAX Orange Line, it didn’t make sense to buy new destination roll signs that included “Orange Line.” Plus, there was simply no room left on the old hand-cranked roll signs.

“It’s good timing to work on this project as we expand our MAX network,” Jones says. “It’s a more flexible system and improves service to our passengers.”

It takes six people about four days to strip out the old communications systems on a train and install the new equipment. More than one-third of the trains are done, but not without some challenges.

“Working on the oldest trains is more difficult than expected because we’re using the existing conduits that pipe underneath,” Jones says. “It takes a lot of effort to pull through the new cables because the space is tight.”

You’ll still see the older signs around for a bit longer. But don’t hold your breath—all MAX signs will be digital sometime in 2016.

Moving forward with cleaner, more energy-efficient buses

Andrew Longeteig

Our buses continue to become more fuel and emissions efficient.

Although our older buses consistently meet federal emissions standards, our newer buses—which make up about one-third of our fleet of 655— emit far fewer particulates into the air.

Why?

A big reason is our newer buses have a diesel particulate filter that removes soot from the exhaust. We’ve also retrofitted 157 of the older buses with these special filters, which remove at least 98 percent of the black powdery stuff.

Diesel particulate filters remove most of the soot from our buses’ exhaust.

Our newer buses also emit less smog-inducing nitrogen oxide (NOx), a pollutant caused by fuel burned at high temperatures. The technology converts NOx into oxygen, nitrogen and water before it exits the tailpipe.

Smart sensors

Another technology that reduces fuel consumption by about five percent is called Sensotop. Made in Germany, it’s a shifting algorithm that uses sensors to change the gear-shifting calibration based on weight and terrain.

For example, a full bus going uphill requires more power—which Sensotop helps provide—while a bus with fewer people going downhill or on level roads requires less. These sensors are on all the buses we’ve purchased in the past three years, and we’ve also retrofitted 40 older buses.

Cool cooling system

In the transit world, we’re also pioneers of a NASCAR-inspired electronic cooling system that reduces engine drag, maximizes horsepower and improves fuel economy by up to 10 percent. Developed for military heavy equipment, it’s on about half our bus fleet. EPA actually gave us a Clean Air Excellence Award for helping bring the technology to the transit market (Woohoo!).
