The speed restriction will affect San Joaquin service of the Oakland to Bakersfield section owned by BNSF Railway, according to Amtrak spokesman Marc Magliari. The speed restriction has been implemented due to anticipated extreme heat this afternoon
Passengers could see delays of a half-hour or more, Magliari said. He encourages passengers to follow Amtrak tweets or go to Amtrak.com to check on routes and possible delays.
