CR 8639 (former PC 8639, NYC 9639). If this unit ever got CR stencils is debatable due to the level of rust, which is just amazing. It looks like it went through a fire. I tried researching when this unit was retired prior to 1980 and why it was retired, but I was unable to track it down.

Briefly stated, during the late 1990's, Conrail worked with several short lines to create a better way to interchange freight. Conrail Express was the result. Here is former CR 8641 (PC 8641) in Conrail Express paint for the Maryland & Delaware, which renumbered the unit M&D 801. Though a former Conrail locomotive and in Conrail Express paint, every CE locomotive always bore its current owner's number.

The unit's original multi-stipe scheme has faded out by this time in 1977, though the unit has still escaped Conrail renumbering.

In 1953 the Lehigh Valley had EMD rebuild two aging NW1's (LV 128-129) into what the Lehigh Valley classed SW900's. In 1955 EMD rebuilt the remaining 9 NW1's (LV 120-127 & LV 130) into what the LV classed as SW900's. Conrail lumped all these units into the SW900 class, renumbering them into the Conrail series 8647-8657.

The Raritan River was not one of the original railroads in the April 1976 merger. The RR had originally been controlled by the Central Railway of New Jersey. 0n April 24, 1980 Conrail officially assumed operations of the railroad, though the Raritan's locomotive fleet, which consisted solely of six SW900's (RR 1-6), had been included in the Conrail roster and renumbering since Conrail's renumbering of April 9, 1976. (Conrail merged on April 1, but the roster did not take effect until April 9!) The six switchers carried the Conrail numbers 8658-8663 and were immediately renumbered as soon as Conrail took official control. Unfortunately, most if not all the Raritan switchers entered storage around 1981, though I do not have exact years. xRR8661 (former RR 4) sits here in the Rutherford dead line awaiting disposition.

Another view of xRR 8661 in the dead line. If memory serves, the Raritan switchers were the only Conrail locomotives in freight service to have yellow hazard flashers on the cab roof.

When the Reading Company rebuilt their old EMC switchers, they classed them as SW900M's, but Conrail lumped all the units into the SW900 class without the modification designation. Because they have full-length handrails running the length of the long hood, former Reading switchers in general are easy to spot, even if painted blue. Here xRDG 8705 (former RDG 1505) works Pavonia in New Jersey. A still-green Penn Central caboose sits in the background.

Looking down on CR 8709 (in forefront). CR 8709 (former Reading Company #1509) still had its VO660 trucks until it was retired.

Prior to the Conrail merger, the Reading Company repainted some of their SW900's into the more modern cream-and-green scheme, as can be seen on xRDG 8717 (former RDG 1517).
