According to the SEPTA web site, the El is short-turning at Erie-Torresdale due to "police activity" at Bridge-Pratt. There's no word on how the bus routes that serve the terminal are being impacted. Since there's no mention of any bus routes being detoured, I'd suspect that there was likely a jumper in the tracks between Erie-Torresdale and Bridge-Pratt. It's highly doubtful that a suspicious package would've caused this incident since, as noted, there's no report of bus detours. Assuming SEPTA decides to tell us what the hell is going on (and don't hold your breath on that one), more details should become available later.
