The heat is on this weekend, so plan ahead


Add extra time for MAX trips

The hottest days of 2015 so far are expected this weekend with temperatures forecast in the low 90s. TriMet riders should drink plenty of water and plan extra time for their MAX trips as minor delays are possible.

Stay cool on the bus

In addition to our air-conditioned MAX fleet, riders can keep cool on board our buses. Nearly all (99 percent) of TriMet’s buses now have air conditioning.

High temps = slower trains in some areas

To ensure rider safety, TriMet reduces MAX speeds by 10 mph in high-speed areas (those above 35 mph) when temperatures exceed 90 degrees.

Speed reduction for safety, equipment protection

High temperatures affect the MAX system in two ways. First, the overhead power wire may expand and sag. Second, rails could swell and bow or kink. Operators slow the trains to prevent damage to the electrical wires and rail.
