I have a 1986 ORER and it has about 11 pages of PC listings, plus 2 1/2 pages of PRR and about a page and a quarter of NYC.
Also nearly 2 pages of RDG, 2 1/2 of EL and about a quarter page of LV listings. There'a also precisely 10 cars listed under ERIE, 4 for NH, 12 B&A, 16 CNJ, a single solitary DL&W car in the 18000 series and one remaining RR box.
