is this a top chord reinforcement

Hi List Members,
The link below shows a RDG gondola. Along the top chord, I see an area that
has been altered - is this a top chord reinforcement, or is this damage that has
not yet been repaired?

Yes, it is an additional angle piece to stiffen the top of the side. Retrofitting this angle was typically done some time after the car was built, but sometimes it was an as-built feature.

That's a partial top chord reinforcement. This type of reinforcement, using a piece of angle, was pretty common. It only needed to be partial, not end-to-end, as a rule, because in the center part of the side was where the greatest bending moment was.

Thanks for sharing this lovely photo of a class GML gondola. Lots to take in. This car must some interior loading device based on the bolt heads on the car side. Many cars had Carmer cut levers, however this car has top mounted rod variety.
Lots of general wear and tear. The Reading Company Technical and HIstorical Society "Bee Line" latest issue (V 41 issues 1 &2 ) has a very nice feature on this car class. Bob Allan Omaha

Yes, reinforcement, and I’d venture that the car’s already got a sag in it, and the reinforcement is intended to not let that get worse!

Top chord reinforcements weren't intended to resist vertical sagging so much as to keep the sides from bowing in and out sideways.
