Train World is a railway museum in Schaerbeek, a municipality of Brussels, Belgium, and the official museum of the National Railway Company of Belgium (NMBS/SNCB). It is situated in the preserved buildings of Schaarbeek railway station and in a new shed built to its north. Although scheduled to open in 2014, its opening was delayed until September 2015, when it was solemnly opened by King Philippe.

Train World, the national railway museum of Belgium, is located at Schaarbeek railway station, incorporating the station building, and was open to the public for the first time on 25 September 2015, having been formally opened the previous day by King Philippe. Until then, €20.5 million had been invested into the project, which planned to attract 100,000 visitors per year from its third year of operations onwards.

The museum is over 8,000 square metres (86,000 sq ft) and displays 22 locomotives. It also displays 1,200 other objects, including an original 19th-century railway bridge. One of the most important objects in the museum is the "Pays du Waes" steam locomotive, dating to 1845, which is the oldest preserved locomotive in continental Europe.
