Commuters Spot 'Pac-Man' Easter Eggs Hiding on This European Subway

Commuting is never fun at the best of times, as you end up crammed like sardines, sometimes in an un-airconditioned tin can, or waiting in a tunnel.

Most cities around the world have some form of public transportation system, from the London Underground to the Paris Metro, but it's Stockholm's trains that are causing a stir online.

Travelers have spotted numerous Easter Eggs hiding on the locomotives in the Swedish capital, and have been sharing their finds online. Stockholm resident Fabiano Souza tweeted a photo on Sunday, showing ventilation grills on the train.

They look fairly inconspicuous at first, but a closer glance reveals 80s arcade icon Pac-Man in the design. The circular vents mimic the game format, which sees Pac-Man chasing and eating on-screen pellets, pursued by four ghosts: Blinky, Pinky, Inky and Clyde.

"Cute Easter egg in the new subway train in Stockholm," Souza captioned the image, which has been liked more than 200,000 times.

Numerous people commented on the post, as they shared more Easter Eggs hiding on the trains, while fellow commuters called for similar revamps in the U.S.

The new trains also feature three crowns, the national emblem of Sweden, and play, pause and stop buttons—commonly seen on tapes on yesteryear—hiding in the grills.

Byron Wright Jr. commented: "How come the United States is not like this? Everything almost seems so typical."

"The Stockholm subway is definitely less utilitarian than those in the U.S. and other countries, many of the stations have really beautiful artwork," Matte5 thought.

Michelle raved: "I love this. A fun little human touch in a utilitarian place like a subway. It's these little treats that delight and make the experience memorable."

Miss V exclaimed: "What the hell, I live in Stockholm and have never seen this!"

@Wint3rmute joked: "Future archaeologists will be so confused."

And a few people questioned why there was only a trio of ghosts shown in the photo.

"Where is the fourth ghost?" Jesjuar asked, to which Souza replied: "It was actually a bit more hidden, down to the right. Unfortunately it's not in this picture."

The Easter Eggs were added to the latest C30 trains, a batch of 48 new locomotives replacing Stockholm's existing CX rolling stock, dating back to the 1970s, The Local reported. All the new trains, delivered by transport company SL, should be in service by 2022.

Elin Lindström, press spokesperson for SL, told The Local: "These figures symbolize in a playful way the Swedish gaming industry which has grown so big. Even if these classic figures don't come from Sweden they're an easily recognizable and appropriate symbol to represent the gaming sector as a whole."

Newsweek reached out to Souza for comment.
