I know this is an old forum, but I've been working at the shipyard for the past couple months (putting in a diesel fuel tank for Quirk Ford). The railroad really interested me, and that's how I found this site.
Reading this forum, I figured I'd let ya'll know, the security there is kind of lax. I would pull up in my personal vehicle wearing a white tshirt and my john deer hat, told them I was working for Quirk, and they let me through.
Not trying to condone tresspassing or anything, but I know you guys just wanna get a closer look. It is pretty cool seeing the engine go back and forth jockeying the rail cars all day.
A few years ago I did roof repairs on the buildings in there, the rail activity has gone down since then. They still operate all day every day, but I can tell a few sections of rail arent used anymore.
Hope this helps!
