The National Transportation Safety Board issued a recommendation on September 30th for SEPTA to suspend the operation of its Silverliner IV fleet due to the threat of fires. The recommendation is the outcome of an investigation by the safety board following a series of fires involving Silverliner IV rail cars. There are 225 Silverliner IV railcars among SEPTA’s 390 passenger-carrying railcar fleet.

Silverline IV railcars are among those used along the Lansdale/Doylestown Regional Rail Line that services the stations in Ambler, Fort Washington, Pennlyn, and Gwynedd Valley.

The Silverliner IV fleet was introduced between 1974 and 1976 by SEPTA’s predecessor, the Reading Company. According to the safety board’s report, the Silverliner IV fleet has not been refurbished since its original deployment.
