High temperatures can affect the MAX system in two ways: the overhead power wire may sag a bit and rails may expand, so trains may need to slow in higher speed sections to ensure the wire and the rails are not damaged.
- When temperatures rise into the 90s, trains traveling in speed zones above 35 mph will need to run 10 mph slower. This will impact some segments of each of the MAX lines and create minimal delays to overall service.
- If temperatures climb above 100 degrees, trains cannot go faster than 35 mph throughout the system. This will create 10-15 minute delays throughout the system.

I wonder how other cities with light rail handle excessive heat? I think there might have been some sort of over site in engineering. They also don't mention the 2900 series buses that the drivers heat wont go off, causing an extremely hot cab even with the ac running. This is a problem they have been aware of for at least a year, and I am still getting buses with heat coming out of the defrost vents with the heat turned all the way off. This is very dangerous and can lead to dehydration, and contribute to fatigue. ]
They care nothing about the polluted AC, nor Fatigue, you are on your own. They may put out fresh water at the garages, but that may be a budget cut item.

Systems are designed for the climate in the area. Portland usually doesn't get that hot.
