Back in 2003, the MARC service HHP-8's were brand new. 15 years later they are circling the drain, just like the Redbirds were after 40 years of service. Here #4913 hangs out at Baltimore Penn Station's track 5.
The brightly colored GP40-2WH's, like #56 seen here, have also been displaced by newer MP36PJ-3C's.
MARC AEM-7's like #4901 seen here, have also disappeared from service, despite having been supposedly refurbished just a few years ago. They will be replaced by diesel power because clean energy and all that.
At least the new NJT ALP-46's and Comet V's have not yet been replaced like the HHP-8's. #4614 and #6033 seen here at Hamilton, NJ.
One problem with Riding the WF Redbirds late in their career was that they only made appearances during the peak periods. Throughout the rest of the day it was all R62's. Imagine the irony when 13 years later it would be all one could do to catch R62's in place of the newly arrived R142/188's. These photos were taken of R62 local and express trains at Woodside. Note the all-day express service and still active 65th St. interlocking and tower.
In this view of Sunnyside Yard you might notice three ALP-46 hauled Amtrak Clocker trainsets. The ALP-46's displaced the Amtrak E60's and then Amtrak turned the slots over to NJT entirely since 90% of the traffic originated in Trenton.
Behind the REA building on the Sunnyside engine tracks, an NJT push-pull set comprised of Arrow IIM cars sits next to an Amtrak Regional trainset hauled by AEM-7AC #919.
The sad state of affairs at the Corona Ready Yard with only a single Redbird trainset in the lineup :-(
