truncated to Cynwyd on May 17, 1986, due to concerns about the Manayunk Bridge over the Schuylkill River. Service to Cynwyd ended altogether in 1988, but fierce political pressure brought resumed service. R8 diesel service between Fox Chase and Newtown ended on January 14, 1983, after SEPTA decided not to repair failing diesel train equipment. The service was initially terminated on July 1, 1981 (along with diesel services to Allentown and Pottsville) and reinstated on October 5, 1981, using operators from the city transit division. This experimental Fox Chase Rapid Transit Line caused a rift in unions within the organization, adding to the March 1983 strike that lasted 108 days. SEPTA management was criticized for the cuts. Vukan Vuchic, the transit expert and University of Pennsylvania professor who designed the former R-numbering system for SEPTA, said he had never seen a city the size of Philadelphia "cut transit services quite as drastically as SEPTA. For a system that is already obsolete, any more cutbacks would be disastrous—and likely spell doom for transit in the Philadelphia region. This city would be the first in the world to do that." DVARP said that SEPTA purposely truncated service and that while other commuter railroad counterparts "in North America expand their rail services, SEPTA is the only one continuing to cut and cut and cut. The only difference between SEPTA and its railroad and transit predecessors is that SEPTA eliminates services to avoid rebuilding assets, while its predecessors (PRR, Reading and Conrail) kept service running while deferring maintenance." RailWorks On November 16, 1984, the Columbia Avenue (now Cecil B. Moore Avenue) bridge near old Temple University Station was found to be unsafe, putting all four tracks out of service north of Market East Station. In December 1984, a temporary bridge opened, allowing service to resume north of Market East Station. Nonetheless, the results of decades of deferred maintenance on the Reading Viaduct between the Center City Commuter Connection and Wayne Junction continued to threaten the right-of-way. In 1992, the bridge was in such poor condition that the bridge inspector actually saw the structure sag every time a train passed over the bridge; further inspection revealed that the bridge was in imminent danger of collapsing. Over the following year, SEPTA undertook a 10-month, $354 million (equivalent to $ million in ) project to overhaul the viaduct, labeled "RailWorks." The viaduct was shut down completely from
