The Rail Mail is a Cloak, that provides the ability to grind on any surface, including spikes. Even though it is used for faster traveling, it may be tough to control, since Specter Knight can still fall into bottomless pits. It can be bought from Manny for 6000 Gold.
- In the official trailer for Specter of Torment, the armor looked very different than in the final variant of the game. In the trailer it is blue, but in the game, it is grayish with a bit of brown.
- Part of the cloak changes color when Specter Knight grinds. Grinding right makes it blue, and grinding left makes it red.
