Watching my steps to avoid puddles of water
Dark gloomy stone walls, dripping with slime
Two sets of raised tracks, each 9 feet apart with too-narrow paths near the damp walls
What if two trains enter the tunnel at the same time? I could be crushed.
Looking behind me, I see misty green trees in the distance. Mystery.
Looking ahead, I am nearly blinded by the bright sunlight. Light.
What an amazing space to enter AS LONG AS no trains enter.
