I suspect 50' box cars might have not been able to remain coupled to one another on those Bronx Terminal 90 foot radius tracks.
On the ex-traction line Claremont & Concord in New Hampshire, in order to deliver a 50-foot car to the Coy Paper Co. in West Claremont, the crew had to remove the knuckles from the locomotive (GE 44-tonner) and the car. A steel bar, a foot or two long, was installed in place of the knuckles. The bar provided enough clearance between the locomotive and car to negotiate the sharp curves.
Of course, having witnessed this procedure, I failed to photograph it. /;-(
