Planks (Mogadishu Transit)

Summary
Found whenever you build planks with the Hammer or scattered across Mogadishu's Campaign.

Background Story
Planks are simply rectangular slabs of wood, manufactured by lumber mills before the apocalypse began. There are many of them scattered throughout Mogadishu Transit, likely because they were supposed to be used as replacements when the tracks broke one day. We'll likely never know, as there's not many sources of reliable information in the apocalypse.

Tips

 * Do not block the entrance on Foxriver Prison, unless you want to troll and/or inconveniently block zombies whilst blocking your own teammates from escaping a very inevitable doom.
 * Use this to block certain places, such as Doors.

Trivia

 * 15 Planks are needed to win the Campaign for Mogadishu Transit.
 * One of the two items required to complete Mogadishu's Campaign, the other being the Rails.
 * The Hammer will have 7 planks for you to build with.
 * At one point in time, the Hammer required planks (scattered across the whole map) to build planks; not only Mogadishu.

Planks blocking a door.
 * This is no longer needed as the Hammer doesn't need planks to build other planks.
