Trains during the hottest hours today, 2:00 pm and 6:00 pm, will need to reduce their speed by 15mph (but not lower than 60mph). This may add on average 10 minutes to trips (longer for longer trips but much less for shorter trips like UP Express). Crews continue to monitor the weather for tomorrow.
Sustained high temperatures beyond 30°C can cause ‘sun kinks’ in steel rails. These bends in the rail can cause a safety issue if trains pass over them too quickly. The temporary slow order is out of an abundance of caution so to ensure customers get home safely. Their patience and understanding is appreciated.
