After the BN-Frisco merger of 1980, many Frisco diesel locomotives were painted into BN colors fairly quickly. When repainted, they retained many of the features such as the Leslie 5-chime horn, front class lights, and nose gyralight. Many would soldier on into the BNSF era losing their roof top beacons and nose gyralights in favor of ditch lights and nose mounted headlights.
