MAX, WES train speeds are limited when temperatures reach 100 degrees or hotter
TriMet is preparing for extreme heat this weekend and into early next week — and we want riders to be prepared as well.
We are coordinating with partners, including the National Weather Service, and monitoring conditions throughout our system. If temperatures reach 100 degrees during this heat wave, MAX and WES train speeds will be limited. Riders should plan for trips to take extra time.
Read more about how and why hot weather affects TriMet, and what you can expect while riding TriMet during extreme heat, at trimet.org/heat.
Train safety
In recent years, TriMet has made improvements to the tensioning system we use to keep overhead power wires on MAX in place during extreme heat, as well as to our MAX and WES trackways. This work has improved our system’s heat resiliency. However, we still limit train speeds during triple-digit heat for safety and to avoid damage to our equipment during extreme temperatures.
MAX is limited to 35 mph at 100 degrees. Although MAX typically operates at speeds below 35 mph in dense areas like the Portland City Center, this speed limit affects how fast MAX can travel elsewhere on the system. Riders should expect delays up to 30 minutes.
WES is limited to 40 mph at 100 degrees, causing delays up to 10 minutes. Above 105 degrees, WES is unable to operate under our agreement with Portland & Western Railroad.
Always check trimet.org/alerts for the latest service information before heading out. You can also sign up to receive alerts at trimet.org/email.
Extreme weather fare policy
During extreme heat, TriMet may activate our extreme weather fare policy.
While this policy is active, TriMet will not turn away anyone riding to or from a cooling center who cannot pay fare. Those who can pay fare should. On the bus, riders who are unable to pay and are taking TriMet to access a cooling space should let their operator know.
The following conditions must be met for our extreme weather fare policy to take effect:
- Multnomah County and/or the State of Oregon declares a state of emergency due to extreme weather.
- Cooling centers (or severe weather shelters) are open to the public.
- TriMet’s General Manager makes the determination that our policy should be activated.
We will notify the public if and when our extreme weather fare policy is put into action.
Staying cool and hydrated
Extreme heat can be dangerous. Following these tips can help you avoid heat-related illness while you’re out and about on TriMet.
- Not all stops and stations have shade. Sunscreen, wide-brimmed hats, long-sleeved clothing, umbrellas and portable sun shades can offer protection against sun exposure. Umbrellas and sun shades should be folded and stowed on board so they don’t block seats, doors or aisles.
- Drinks are allowed on TriMet in closed containers, including water bottles and cups with lids. It’s a good idea to carry water or another hydrating drink, especially if you may spend an extended amount of time outside in extreme heat.
- All TriMet buses and trains have air conditioning on board. However, riders should be prepared for trips to take longer, including potentially longer waits at stops and stations.
Your safety matters to us! We encourage everyone to take precautions during extreme heat and stay safe on TriMet this summer.
