Too many dangerous selfies have forced the closure of the outdoor carriage on New Zealand’s iconic Coastal Pacific train.

The 350km route between Picton and Christchurch takes in some of the South Island’s most beautiful scenery, which tourists frequently try and capture from the train’s viewing carriage.

However, travellers are putting their lives at risk by leaning out of the carriage to take selfies, photos and videos of the landscape.

“Despite the number of signs and announcements on board our trains pointing out the dangers of this, we have seen passengers leaning out with selfie sticks, iPads and their bodies, often unaware of an approaching tunnel which could cause a tragic incident for themselves, and others in the carriage,” said Katie McMahon, general manager of KiwiRail group, which operates the service.

“We simply have to stop adults and children leaning from the carriages or we would not be discharging our duty as a safe transport operator.”

As a result, the company has launched a review, during which the viewing carriage will be off limits.

Potential solutions could involve glass windows, narrow bars or an inclining barrier, according to McMahon.

“We hope to have a solution in place shortly that will allow the carriages to re-open safely,” she added.

The move comes as so-called “influencers” are increasingly coming under fire for posting pictures that seemingly promote risk-taking to get the perfect shot.

Earlier this month, a picture of a travel influencer couple in Bali was branded “dangerous” and “stupid” by online commenters.

Kelly Castille and Kody Workman, who created Instagram account Positravelty, posted a photo of Workman holding Castille over the side of an infinity pool in Ubud while they kiss, with a sheer drop below.

While some were impressed by the pair’s ingenuity, others were quick to censure the couple for the “terrifying” and “idiotic” stunt.
