#1947 – Pacific Greyhound Lines

1948 Greyhound Silverside

1948 Greyhound Silverside

Initial Service

Originally this GM, PD-4151 “Silverside” was delivered new to Pacific Greyhound Lines in San Francisco as K-104 in April 1948. Of the 2000 post-war GM “Silversides” built during 1947 and 1948, most were PD 3751 models seating 37 passengers. There were 357 PD 4151s built, all in 1948, seating 41 passengers. Most of them went to Pacific Greyhound Lines and were numbered K91 to K323 (at that time, K was the letter designation for any bus assigned to Pacific Greyhound Lines). They were operated on Pacific Greyhound’s routes throughout California and Oregon. Because of their larger seating capacity (41 instead of 37), they were generally used on shorter intercity routes radiating out of San Francisco and Los Angeles to points north, east, and south.

Service History

During 1963-4, Western Greyhound Lines refurbished approximately 90 GM PD 4151 Silversides for suburban routes in the San Francisco Bay Area and installed fare boxes for this service. Greyhound expected an additional 5 to 7 years of service with the refurbishment of these buses. They were easily identified as suburban buses by the addition of the number 9 to the three-digit numbers on the buses. Thus PGL K104 became WGL 9104. By 1970 Greyhound’s remaining Silversides were used sporadically, usually during the busy summer months and peak travel days around Thanksgiving and Christmas. By 1971 there were a dwindling number of PD 4151s still in operation and by that fall they were stored in the back of the Greyhound Maintenance Facility in San Francisco. The last known days of operation of Greyhound’s Silversides was in December 1971. 

 

 

Pathway to PBM 

In early 1972 Greyhound sold its last group of Silversides to a bus company in Peru but the very last Silverside bound for Peru was never shipped. This bus sat in a storage lot in San Francisco until 1980 when it was re-acquired by Greyhound and eventually became part of Greyhound’s Historic Bus Fleet. The Pacific Bus Museum acquired #1947 in January 2023 and is proud to have this historic coach in the museum’s collection.

What People Love 

The Silversides are an iconic part of Greyhound history. These operated side-by-side with their contemporaries, Scenicruisers. People have many fond memories of both buses cruising the highways and interstates across the country.

This bus is a must-see when you come to visit the Pacific Bus Museum.
