Bridge Tending on the 
Penn Central

Mystic River Bridge, Mystic Connecticut

I lived in Mystic, Connecticut for the summer and fall of 1972. I had the use of a good camera and was a short walk to the former New Haven ‘Shoreline’ and so I often watched the trains, mostly Penn Central passenger trains. As a child, my family rode the New Haven occasionally and I remember riding along and seeing the ocean much of the way. In 1972 my interest in railroading was mild at best, but I couldn’t help but look up when I heard the rumble or horn. A friend and I had recovered and restored an old rowboat, which we kept tied up at a marina on the Mystic River across the street from where I was living. This provided me with alternative transportation, and so this little story. The marina was in the area between the Route 1 highway bridge and the downstream railroad bridge, and I often rowed that stretch of the river when I wasn’t working painting houses.

Before — 1968-1972

Having worked on a sport fishing boat in Niantic, Connecticut in the early 1960’s and having to help guide the boat through the narrow channel between the Route 1 bridge and the New Haven’s lift bridge, I was acquainted with the routine of notifying the bridge tender when wishing to pass through the channel. It was the same routine in Mystic; once or twice we took the boat over there and had to pass through the bridge. I got a kick out of blowing the klaxon and seeing the bridge open. Back in the ‘60’s, the New Haven trains were shiny and flashy but by the time I was back there they were dirty and looked worn out. Penn Central didn’t really care about passenger trains and they did their best not to dissuade anyone of that attitude.

One day I rowed down to the railroad bridge, tied off the boat, and climbed up to have a closer look at the bridge. The bridge tender invited me in and so started a ritual of rowing out and visiting that summer. I think I recall his name as Bob but do not remember his last name. I pretty much stayed out of his way, but he showed me how everything worked. He wouldn’t open the bridge for boat traffic if a train was due within a certain period of time, and sometimes the boat traffic piled up.

The bridge was a double track center bearing through truss swing bridge dating from 1919. It had an interlocking plant that protected the trains when the bridge was not fully closed and locked in place. Rails on the bridge locked into place when the bridge was closed, ensuring safe and smooth ride across the joints. There were derail switches on each track on both sides of the bridge. These would prevent a train from going onto the bridge if it wasn’t fully closed and locked in place or over the bridge abutment and into the river if the bridge was open.

It was an enjoyable summer there and I took a few photos to remember it by. I wasn’t interested in a railroad career back then and don’t remember much detail about the bridge operation. Penn Central was a depressing operation and I moved on. What I never imagined were the changes that were coming to the railroad and to the Mystic River bridge and that I would spend almost forty-five years (so far) working in the railroad industry.

So, in doing some research for this story, I came across a series of photos in the Library of Congress taken by W.H. Moore in 1968, just before the Penn Central took over the New Haven, for the Historic American Engineering Record that show the bridge in great detail. They are too good to pass up and since they are in the public domain, here are a few of them.

All of these and a few more that I didn’t include here are covered by the following citation:

After — 1991

Traveling back to Mystic many years later, I wanted to see the replacement bridge that Amtrak had installed. Rebuilding the northeast corridor had been front page railroad engineering news for several years and the Mystic River bridge was one of the features. It was finally finished, and I was able to go by and have a look. The difference between 1972 and 1991 was amazing. The bridge was in operation, still a swing span truss, but the bridge tender’s cabin was now on top of the bridge structure. Welded rail, concrete ties, elastic fasteners, deep ballast, and beautifully surfaced double track. Derails were still in use protecting the trains and the bridge. Bob was most likely retired, and I didn’t try to meet the new bridge tender because I couldn’t find the ladder. Train traffic across the bridge was busy during my visit, and I was content to see it in full operation.

Of course, even these ‘after’ photos are outdated now. Amtrak has electrified the corridor from New Haven to Boston and the entire railroad is lined with catenary support structures and wires. I haven’t been back to examine the electrified bridge, but have ridden across it on a couple of occasions behind now-retired AEM-7’s. The only diesel-electric locomotives you’ll see there now are occasional freights of the Providence & Worcester Railroad and Amtrak work trains. But the new Mystic River Bridge should be around for a good long time.

Of Time and the Railroad

Southern Pacific Cab-Ahead 4274 passes Rocklin, California on November 30, 1957, headed for Donner Summit.

It’s the last day of November in the foothills of the California Sierra-Nevada and remarkably warm for the time of year. The station-board by the main line reads “Rocklin.” There is no longer a station building here but you can usually spot the location of a former Southern Pacific station by the presence of a mature palm tree, and in 1957 Rocklin has a fine specimen.

At one time, this was a staging point for the long climb to Donner Summit, but its roundhouse and its busy turntable are long gone. In 1957 Rocklin is a quiet, peaceful and unspoilt place. (Today, in 2022, there is an elevated highway interchange at this location.) On either side of the tracks a few wildflowers mix with the tall grasses, including some California poppies which have been dormant over the hottest months of the Summer. Jointed rails creak in the midday heat.

Editor’s Notebook

Many of our readers will have fond memories of a Lionel Train set under the Christmas tree. It’s that time of year again, and I wanted to share a video we produced last year with artist Angela Trotta Thomas, who features Lionel trains in her work. Angela’s art is sure to evoke many happy memories and watch for her special connection with singer/songwriter Neil Young.
