I have seen at least four articulated cars(two car sets) to hold twenty foot trash containers lettered for NYSW. One was number 100117. These are identical to the ones that EPIC uses for trash hauling on the River Line. One car was in a freight consist, and was empty, on the River Line. The others were at the Resources interchange track for NWSW/NS Croxton. I work at Resources and nobody seems to know anything about these cars. They are red and appear to not be new cars.
