Goodman Street Yard is a railroad switching yard near the intersection of Goodman and University . It borders the parking lot to the Village Gate, and is visible from the Legal Wall and from the Public Market. An attraction of this yard is the fantastic Graffiti often found on or appearing on the cars. This site documents some of the art that can found at the yard.

However, the most unbelievable thing of all was what happened at the CSX's Rochester Yard (formerly Conrail's Goodman Street Yard). I got a hold of the Yardmaster and asked if we could possibly get a yard tour. At first, he was very skeptical about the idea, but after I explained the goals of TAMR, he was extremely glad we wanted to come and extended an invitation to our group. We started with a tour of the yard tower, which gave us an inside look at railroad yard operation. We also got a tour of an active ex-Conrail caboose (Rochester is one of the few locations on the CSX system with an active caboose pool used on locals). As thanks, we received lots of official CSX items (sunglasses, payment sheets, yard diagrams, timetables, operating manuals, etc.) to take home as souvenirs. But the best part of the yard tour, by far, was the cab ride in a GP38-2. After it came back from a local, we piled on and were treated to a cab ride around the yard. The crew was very friendly, explaining to us all the functions and controls.
