I wrote about Pennsylvania Railroad’s Rockville Bridge in my book Railway Masterpieces published in 2002.

“The third bridge at Rockville was started in 1900, and opened to traffic in 1902. It is listed in the Guinness Book of Rail Facts and Figures, as ‘the world’s largest stone arch railway bridge over a river’. It consists of 48 stone arch spans.”

Last month Kris and I paid a visit to the Rockville Bridge. As we approached this magnificent viaduct a westward Norfolk Southern freight was crawling across, yet we had arrived too late to catch the head end of the train on the bridge.

We decided to wait a little while to see if another freight would come along.

Finally after about 45 minutes, I could hear a GE diesel chugging away on the far side of the Susquehanna. As the train started across the bridge, the evening sun emerged from the clouds, producing some very fine light to photograph the train.

I exposed these photos with my Nikon Z6 with 70-200mm lens firmly mounted on my mid-1990s vintage Bogen tripod.
