A trio of Alco PAs are in charge of train number 176, the Speedbird on a cold day in 1952. Originally named the Advance Arrow, this train was originally inaugurated as a heavyweight second section to the popular all-Pullman, no extra-fare, streamlined Arrow. By 1948, enough equipment was available to partially re-equip the train, and it was rebranded and relaunched as the Speedbird in June of that year. Although still all-Pullman, the train is mostly made up of rebuilt heavyweight sleepers. The normal lightweight diner is likely in the shop, as there is a replacement heavyweight diner in the consist today. Holiday traffic is still heavy, and the train still has a sizable amount of head end traffic to pay the bills, but the end for this train is near. Earlier in 1952, the train was combined in non-peak months with the all-coach Cincinnati Clipper east of Pittsburgh. Although the train has just regained independence in November, in a few months the train will be combined year-round with the all-coach Clipper between Boston and Chicago, and the name will be dropped by 1956.
