While traveling in Essen U-bahn i saw this grainy or sort of sand thing. Do you know what that is and what’s the use?

  1. Saw that design and thought “wait, isn’t it the Ruhrbahn?”

  2. It’s a box of sand, on slippy days they use the sand to cover up any delays they have.

    This is sand. It pours out in front of the wheel so the wheel can get traction on steep inclines or in rainy or icy weather. The window is for maintenance personnel to easily check the level
