Gettysburg PA traffic?

I'm heading out to Gettysburg tomorrow - what's traffic like going through town these days? I'll be there for a good bit of the afternoon tomorrow, and was wondering what my chances are of seeing something roll through town. Any help or info is greatly appreciated!!!

Sorry that I didn't catch this when you posted it, I haven't been on here for a while. Gettysburg usually has a train heading west around 10am-1230pm, and returns eastbound between 6pm-8pm. Extras run as needed, dependent on traffic needs. Gettysburg and Northern sorts cars in the am, leaves for their run around 9am or so, and depending on switching duties in Biglerville, Aspers, Gardners and Mt Holly Springs, returns to Gettysburg around 3-4pm.
