TOPEKA, Kan. (AP) — Amtrak officials say a rail line is in need of additional funding in order to keep passenger service moving through southwest Kansas at a profitable speed. But the Topeka Capital-Journal reports that Amtrak needs to have the track maintained at a proper level so trains can move quickly and keep passenger service on time. The track is owned by BNSF Railway and is used by Amtrak for about four passenger trains a day, including two runs by the Southwest Chief from Chicago to Los Angeles. BNSF is willing to maintain the tracks to allow freight trains to travel at 30 mph, but not the 79-mph that Amtrak wants to maintain for passenger trains. Amtrak has approached Kansas, Colorado and New Mexico about funding the $100 million for repairs.
