Train to Nowhere

From publisher blurb: One of Pappa Doc's Railway crews have gone missing, deep in the wilds of Alabama. The PCs are tasked with tracking them down and rescuing them if possible. But what exactly caused an entire team to just disappear? Not all is as it seems, and the PCs will have to keep their wits about them if they're not going to become snacks for the Infected. A one-shot scenario for 1-6 players and estimated to take 4-6 hours.
