No, but they have one IRL. Honestly, you don't want to do that kind of thing without knowing how to do it properly. And knowing the schedule of the trains, which is always off from what is listed. Always.
When it comes between trucks and trains, trains always have right of way.
There aren't many rail lines left in North America anyhow, considering how many countries and tribal territories they cut through, with a customs stop at pretty much every one. Easier to take the bus, cheaper bribes and faster searches. And driving on the rails would certainly get you noticed on customs patrols, which would watch the rail lines carefully as cargo trains do still move a lot of goods around.
