    Anybody else notice the signal upgrades BNSF is making on the Thayer North Sub east of Springfield? Most of the old Frisco
    'searchlight' signals are being removed and replaced with new 3-light units. The work can be observed along US 60, which parallels the sub in Webster County.

    I'm guessing these signals had to have been at least 60 years old?

    Same thing here, they have done over 400 miles of CTC signal replacements and additions. We were told it is due to the Fed mandated implementation of the PTS (positive train separation), that might be whats going on there.

    You are correct, searchlight signals are not compatible (at least not economically so) with the Wayside Interface Units (WIU) that are a part of I-EMS, the system being implemented by the freight railroads to meet the federal Positive Train Control (PTC) mandate. This is not an issue limited to former Frisco lines, or even just to BNSF.
