Saybrook Junction has changed a lot since the days the Valley Line crossed here at-grade (just beyond that first catenary tower). The freight house has been moved to the west (closest) end of the passenger station, and is now a pizza restaurant (with LOTS of railroad decor, natch), the station platforms are now high-level, there's an overhead pedestrian bridge to cross the tracks, and there're wires - something not seen east of New Haven until the 1990s.
But one thing that hasn't changed - other than the equipment and frequency - are the trains. Trains still go through Saybrook Junction. And some of them go pretty fast.
