With record-setting high temperatures causing disruptions to MAX this weekend, TriMet is immediately halting service on all MAX lines from now until the start of service on Tuesday, June 29. The historic high temperatures, which are approaching or exceeding 110 degrees in some areas, are straining the power grid and the overhead wires that power MAX trains. The MAX system is designed to operate in conditions up to 110 degrees. Forecasts show it will likely only get hotter today without sufficient time to cool down.
On Sunday, MAX Blue, Green and Red lines were disrupted due to heat-related mechanical issues. The MAX Yellow Line encountered similar heat-related mechanical issues near N Killingsworth station. As high temperatures continue to occur through Tuesday morning, there is the strong possibility of further heat-related disruptions later.
Riders will want to consider other travel options if they were planning on taking MAX today or tomorrow. WES riders will also want to plan ahead on Monday, as WES cannot run when temperatures exceed 105 degrees. TriMet suggests riders use regular bus service if that’s possible. Buses will continue to run on their normal routes unless they are experiencing delays. If you must travel during this heatwave, check http://trimet.org/alerts before you go.
