I was doing a job in Corona, Ca. and had to make a run to San Bernardino for some personal business. The freeway runs parrallel to the BNSF main from Cajon pass through Riverside & Corona to the Santa Ana Canyon. Anyway, I saw a short train on the BNSF, 2 gp units on the point with about 6 cars and a CABOOSE. It was running in reverse on the BNSF main, and may have had the caboose in place because the locomotives were doing a backing move at speed on the mainline, but I didn't even know they had any cabooses left! The caboose was in Santa Fe colors, no mention of BNSF that I could see on it.
