Diesels were being used on all trains by 1953, with the exception of ten-wheelers number 181 and 183 pulling passenger trains numbered 3 and 4 between San Rafael and Eureka with number 182 on standby. The #3/#4 trains offered sleeping cars, a cafe-lounge in addition to coach cars. Passengers from San Francisco would take Greyhound Buses from the San Francisco Ferry Building at the base of Market Street to San Rafael. NWP locomotives 112, 140, 141, 143, and 178 plus SP numbers 2345, 2356, 2564, 2582, and 2810 were stored at Tiburon for emergency use; but steam power had disappeared by 1955. On November 10, 1958, all mainline passenger service was discontinued south of Willits. The only remaining service was a tri-weekly Willits-Eureka round trip, operated by a single Budd Rail Diesel Car, which ran until April 30, 1971. When Amtrak took over intercity passenger rail service on May 1, 1971, it did not continue service on the NWP.
