The first stamp from left was issued in 2008 to commemorate the 125 years of Oriental Express.
The Orient Express was the name of a long-distance passenger train originally operated by the Compagnie Internationale des Wagons-Lits. Its route has changed many times, and several routes have in the past concurrently used the name, or slight variants thereof. Although the original Orient Express was simply a normal international railway service, the name has become synonymous with intrigue and luxury travel. The two city names most intimately associated with the Orient Express are Paris and Istanbul, the original endpoints of the service.
On June 5, 1883 the first 'Express d'Orient' left Paris for Vienna and the train was officially renamed Orient Express in 1891.
On 14 December 2009, the Orient Express ceased to operate and the route disappeared from European railway timetables, reportedly a "victim of high-speed trains and cut-rate airlines."
