Not sure of the date, but the critical fact is that it was partially demolished, as the photos with the article show.
This collapse has nothing to do with bad engineering, poor materials, age or obsolescence (except indirectly). It's likely about a contractor screw-up of some kind during the demolition process, such as a failure to brace, abutments that tilted or moved or were undermined, a local overload, etc.

zugmann caldreamer here was a coal train derailment on it a number of years ago. Did not hurt the bridge at all, A number of the coal cars dropped into the river though. They derailed because a portion of the bridge collapsed. And don't forget Shocks Mills downriver. Middle of that gave out during Agnes.

It sems every picture of a PRR stone arch bridge has metal bracing on it.
