Don't forget ex ATSF 3751. On the break-in run from San Bernardino to Los Angeles it pulled a string of baretable flats from the San Bernardino "B" yard into L.A. Ironically there was one of the last occupied uses of a caboose on the Santa Fe BEHIND STEAM!! Hank Graham rode in the wide vision caboose on that trip. I'd have to find My slides for the exact date. It is debatible if baretables are "revenue", but it was indeed freight cars being pulled behind steam for loading later in L.A. so I feel that it counts.
