Two weeks ago Philadelphia regional rail commuters, a large group to which I belonged for a number of years, experienced a week from hell. On 2 July a yard inspector for Septa, the Philadelphia region’s transit agency, discovered a Silverliner V railcar tilting. For those not familiar with Septa, the Silverliner Vs have been in service for only three years and have been long touted as the future of the Philadelphia commuter rail service. After inspection Septa discovered the tilting railcar suffered from a fatigue crack on the equaliser beam, specifically where it was welded to connect to the wheel bearings. The beam forms part of the truck, which is what connects the railcar to the rails, and any failure at speed could have resulted in an accident, possibly a derailment. The transit agency then quickly inspected the remainder of its fleet of 120 Silverliner Vs. It found the same fatigue crack in a total of 115 cars. By 4 July, Septa pulled all 120 Silverliner Vs from service.
So what happened? At this point, we do not know. Septa continues tests to discover just what happened and just what can be done to repair the cars. Because, with a fleet of approximately 400 cars, the Silverliner Vs represent 1/3 of the fleet. And with fewer seats and fewer trains, commuters attempting to ride into the city, particularly from nearer-in suburbs, find trains bypassing stations because they quickly reach capacity.
Consequently, Septa has instituted a reduced service—a modification of the Saturday service—with additional service on subways and other high-speed lines. Additionally, Septa has agreed to lease additional trainsets, i.e. locomotives with passenger cars, from other regional transit agencies: Amtrak, New Jersey Transit (NJ Transit), and the Maryland Area Regional Commuter Train Service (MARC).
