Here's the sad tale of the Reading Shops-built composite cabooses: They were all sidelined by Conrail shortly after they took over because of their all wood bodies and Duryea Cushion underframes. An individual from Phillipsburg, who tried to save as much of the L&HR as he could, sued Conrail over scrapping/abandoning the L&HR. As settlement, he received 6 or 8 of the cars, and had them shipped to the Ingersoll-Rand plant in Phillipsburg, along with the L&HR flanger (ex-O&W). The flanger was kept inside for a number of years, but the cabooses were not. Almost as soon as the cabooses arrived, I-R sent letters telling him to have them moved.
They sat and sat for a number of years, with the cupolas, roofs and siding leaking water, which also warped the floors very badly. Eventually, I-R tore up the track inside the plant, and the cabooses were going to go, too.
Apparently, the Phillipsburg Rail Historians managed to get various people to adopt them, and they all found homes, more or less. I did see one of them in the yard of a garbage hauling company along Route 46 above Belvidere. Looked pretty sad.
