Thursday’s expected extreme heat could cause Metra to put the brakes on some of their equipment, resulting in some delays for riders, the commuter rail agency said.
Metra issued an extreme heat alert Thursday morning, stating that because of the extremely hot conditions forecast for the Chicago area over the next several days, riders may experience delays of between 10 to 15 minutes.
Metra explained that when temperatures exceed 95 degrees, it’s necessary to operate the trains at reduced speeds to compensate for heat-related stresses on tracks, switches and signals. Metra says that during this heat event, they will have all resources on standby so that crews can quickly respond and restore service.
The National Weather Service has issued a heat advisory through Friday for the Chicago area. High temperatures will be in the low to mid-90s Thursday and in the mid- to upper-90s on Friday. Heat indices were expected to be between 100 and 105 today and between 102 to 108 on Friday, according to the weather service.
As of about 9 a.m., the official temperature in Chicago was 86 degrees, according to the weather service.
