The train has an average speed of just 37mph — likely because every carriage is bulletproof, making it much heavier than a regular train.
The elder Kim also had a flat-screen TV, wooden desk and a computer at the end of one of his carriages. The desk and computer are now being preserved at Kim's mausoleum in Pyongyang. It's not clear where the TV is.
Unlike his father, however, Kim seems to prefer using Apple MacBooks to desktop computers.
The elder Kim used to travel in opulence — he stocked his train with Bordeaux and Burgundy red wines, silver chopsticks, and whatever else he fancied from around the world. This is according to Konstantin Pulikovsky, a Russian official who travelled with the late North Korean leader in the early 2000s — when the rest of North Korea was reliant on humanitarian aid after years of famine.
"It was possible to order any dish of Russian, Chinese, Korean, Japanese, and French cuisine" on board, Pulikovsky said. This undated video shows a section of the train's dining carriage under Kim Jong Il's reign, which has reportedly since been renovated.
It's not clear whether Kim Jong Un stocks the train as opulently as his father did. But he's not known to be one to skimp — he reportedly enjoys Swiss cheese, Cristal Champagne and Hennessy cognac.
