Is that a grocery store inside this Seoul train?

A tourist had been taking the underground subway in Korea, only to stumble upon this train cabin that seemed to have been converted into a grocery store.

He then uploaded a photo of the unusual sight online, and it soon went viral on sites such as Reddit and Imgur.

It is not known whether the train was converted into a grocery store or if it was transporting goods.

However, aside from its unusual location, the photos shows what seems to be an average grocery store, complete with a cash register and refrigerated glass displays with lighting.
