The beautiful Old Saybrook station in Connecticut was busy with Northeast Corridor trains on a cloudy May morning in 2013. First, southbound Amtrak Northeast Regional train 93 stops from Boston. Next, the northbound Northeast Regional train 170 flies by. Then, the northbound Acela Express train 2154 heads to Boston. The signals change from "approach" to "clear" and the southbound Acela Express 2163 roars by with lots of horn. The southbound Northeast Regional train 173 passes by on the way to Washington as rain falls. Finally the northbound Northeast Regional train 172 with a HHP-8 locomotive stops and departs toward Boston.
