The low door cars were retired from service in 2005. 25 of the cars were sold to Utah Transit Authority (UTA) for the FrontRunner service, and 20 were leased to Metrolink in 2008 to help with an acute car shortage there. In March 2011, Metrolink returned the cars to FrontRunner upon the expiration of the lease. Metrolink also leased 15 cars directly from New Jersey Transit in 2009. These cars have not been used since 2011. The Comet I cars have become popular with western commuter lines as the low door setup is compatible with the low-platform stations in use. Eight Comet Is were sold to SEPTA, but are now out of service and put into storage. Some of these have recently been used in work service.
