More efficient passenger power was needed as the PA's and E-units began to rack up the miles, and in the spring of 1967 the SP began taking delivery of ten new 3600 h.p. SDP45s from EMD (3200-3209). On May 2, 1970 the SDP45 3204 leads a five car No. 52, the Los Angeles-bound San Joaquin Daylight at Lathrop, California. Photo by Al Holts, from my collection.
