First pictures have emerged The 'love train' used by North Korean leader Kim Jong-un to meet his Chinese counterpart.
The distinctive green and yellow armoured train that pulled into Beijing on Monday is the same one used by his father Kim Jong-il in May 2000 when he too travelled to Beijing to visit Jiang Zemin, China's leader at the time.
According to a 2009 report in the South Korean press, the train at the time consisted of about 90 armoured carriages, with two separate trains travelling ahead and behind it to handle security.

Because of its weight, it moves slowly - its average speed is reported to be 37 mph - but inside, it is relatively high-tech and luxurious.
The train is reported to come complete with luxurious seating, dark wood panelling and plentiful supplies of alcohol.
According to an account by Konstantin Pulikovsky, a Russian official who travelled with Kim Jong-il to Moscow in 2001, the train was stacked with cases of Bordeaux and Beaujolais, which had been flown in from Paris especially.
One Russian official who travelled with Kim Jong-il on the train to Moscow in 2001 said that live lobster and other delicacies were regularly sent to the train as it travelled, the Washington Post reported.

It is often been reported that that the Swiss-educated Kim Jong-un has inherited his father's fondness of the finer things in life, especially Swiss cheese, Cristal champagne and Hennessy cognac.
