A River Runs Through It

A babbling brook runs between the rails of the Brooklyn bound Q train at Atlantic Avenue. There is a lot of water and a pretty decent current there. It’s a major improvement from the waterfall that sometime resulted from a busted water main there and lasted for a few days.

The channel between the rails is there for safety – since most statons have no clearence on the sides, it’s the only place to hide from the oncoming train. The brown color of the water is due to tiny rusty shavings of steel that cover everything near the tracks. Fecal matter might play a role in that too.

The little riverlet has been there for so long that people started throwing coins there for good luck. Let’s hope no bums will decide to try and collect them.

As a bonus, here’s a picture of a subway sign from my trip to Japan. One of these days I need to sit down, sort the pictures and write everything up.
