The Oscawana Tunnel is several miles north of the Metro North Croton yard that marks the northern limit of electrified service to Grand Central. Half Moon Bay roads provides a view of the northern end of the yard including M3's. M7's and the A-34 traction power substation. We can also see two of the main tracks are being reballasted.
Half Moon Bay Rd leads to Senasqua Park that sits directly adjacent to the former New York Central CD tower, now inhabited by the Metro North signal department.
Even on a reduced port-COVID schedule, there is still plenty of Metro North action with hourly Poughkeepsie diesel trainsets. CDoT owned P32AC-DM #230, seen here wrong railing through CP-36 on track #4 south of the tunnel is still in the New haven livery that has been replace by the Coke Zero scheme on CTRail units. CP-36 provides access to the Croton freight yard from the north and is one of the only instances of a Metro North signal mounted on a high signal mast. On tracks 1 and 2 is the milepost 36.6 automatic cab signal indication point.
Before the pandemic MNRR weekend northbound and southbound Poughkeepsie trains tended to meet in the vicinity of the tunnel and this appears to still be the case with NH #230 and its train meeting a southbound set with MNRR P32AC-DM #201.
Continuing with the whole opposite day thing, Amtrak Train 48, the eastbound Lake Shore Limited, appeared on the normally northbound track #1 with an unidentified private car in tow. Today's New York section of the LSL also consisted of two Amfleet II coaches, two Viewliner sleepers, a Viewliner diner and a Viewliner baggage car.
A pair of Amtrak Empire Service trains were also in the mix with P32AC-DM #702 heading up the northbound and Phase V heritage painted #708 on the northbound.
