50' Mather stock cars
I assume many of this group are on the OpSig group that discussed Live Stock Operations today. The question concerned the 50’ Mather stock cars.
Mather cars were generally leased cars. Beginning in 1952 Mather spliced together pairs of 40’ cars, retaining the doors of both cars, producing a 50’ stock car. Cars in that configuration were operated by the

NYC (as NISX painted Jade Green in 1966). The NISX cars were frequently seen on the Q. Photo NISX 3169 Freight Cars - Lake States Railway Historical Association (lakestatesarchive.org) and Freight Cars - Lake States Railway Historical Association (lakestatesarchive.org)
CB&Q, 40 cars (50200-50239) for use in sheep and hog service which lasted until at least 1968.
Maybe Doug or someone else can add more details to this discussion.
