Crown Coach Corporation
Crown Coach Corporation was founded by D. Brockway in 1904 as the "Crown Carriage Company" in Los Angeles, California, eventually moving factory operations to Chino, California. Crown went out of business in 1991.
Beginning as a motorized truck builder, Crown expanded into passenger vehicles and quit building trucks. Crown Coach was the creator of the original large, flat nose (transit style or "Type D"), high capacity school bus. Their first example appeared in 1932. Working with Tanner Grey Line of Los Angeles, Crown designed the well-known Art Deco coach that eventually led to a school coach utilizing unibody construction, mid-ship underfloor mounted commercial truck engines (often by Hall-Scott, Detroit Diesel or Cummins; a handful of them had Caterpillar engines) and off-the-shelf Class 8 truck parts, which made them economical to operate. Starting with steel skins, Crown later switched to rust-resistant aluminum panels.
After being purchased by General Electric a few years prior, operation ceased in 1991.
As the state of California does not place restrictions on the service life of school buses, owing to their aluminum body construction, many Crown Coach Supercoach school buses remain in active service well into the second decade of the 2000's, with all of those buses being at least 26 years old and many significantly older.
