Number 9767 was built in October 1930 by Pullman ( body c/n 458 ), powered by an EMC No. 148 400 horsepower diesel. Originally built with a 15 foot mnil apartment, it was converted in 1930 by the CB&Q to a 30 foot mail apartment.Like all self-propelled cars, the 9767 has a varied and interesting career, though perhaps more distinguished thak most. In her later years she was painted a distinctive silver gray and pulled one of the finest riding cars on the system, the Silver Pendulum, between Saint Joseph and Brookfield, Missouri, ihere the train connected with the Kansas City Zephyr. When this passenger train was discontinued, both the 9767 and the Silver Pendulum were moved to Lincoln, Nebraska to become the Lincoln - Sait Joseph via Wymore Local passenger. Motor failure due to a broken connecting rod did severe damage to the diesel and the 9767 was taken out of service in December 1961. The PMC body waqs set on Jhe ground at Beardstown, Illinois to serve as an enginemen's locker room. However the Silver Pendulum, built in 1941, saw more service.
