Cross-channel rail operator Eurostar resumed its service to Brussels on 1 March after suspending operations for over two weeks following the Belgian rail crash.
Services to Brussels had to be suspended after two commuter trains collided in the nearby town of Halle in mid-February killing 18 and injuring nearly 150 people.
Eurostar, which limited its London-Brussels operation following the crash, will now operate five direct services between London and Brussels on Saturday and Sunday, and has resumed a full schedule this week.
The crash prevented all train services, including Eurostar who offered a shuttle bus-service from Lille, to operate to Brussels.
This had been the latest in a string of high-profile problems for the international carrier after being criticised for cancelling trains over Christmas due to the weather and a mysterious break-down in Kent soon after the crash outside Brussels.
