Amtrak marks PTC progress on BNSF lines

Amtrak, working with BNSF, will the week of June 11 implement Positive Train Control (PTC) on BNSF-owned subdivisions that host the Southwest Chief and California Zephyr, marking the first activation on host-owned territory used by Amtrak. Full PTC activation on BNSF routes that host these two long-distance trains is expected by the end of August.
