• Yellowbonnet: one of two Santa Fe paint schemes. The standard freight scheme from 1972 until the BNSF merger was dark blue with yellow on the front, with the same color division as the warbonnet scheme. It is also known as Bluebonnet. Yellowbonnet can also mean a warbonnet unit with only the red painted over, resulting in a silver and yellow locomotive; this was used on passenger engines transferred to freight service after the formation of Amtrak.
