As far as I know, both the old route and the bypass have PTC installed. BNSF Railway completed installation between Portland and Seattle about six months ago. The bypass was constructed with PTC. The deficiency is that the locomotives and cab cars are not yet fully equipped. Until the both the ground and moving portions of the system are in place, tested and certified, PTC cannot be activated.
