Book excerpt: A reflection of the effects of highways--and their hugely subsidized trucks--upon railroads, and of the incompetence of the Southern Pacific. The trucks took much rail freight on the coast, the SP--partly through government rules & inertia--failed to meet the competition; many lines were closed, most of the rest were sold to small, hungry, competent firms. This is the story. It is well told in a style familiar to rail fans: lists of stations, engine rosters, control blocks. Abundant photos, a few in color. Current through the visit of the X2000 in mid-1993. Annotation copyright by Book News, Inc., Portland, OR.
