Transport Superintendent Asanka Samarasinghe said the train is set to operate according to its usual schedule from today onward.
The accident occurred on April 24 when the train, travelling from Beliatta to Maradana, derailed at Wadduwa Railway Station, with 11 of its 13 compartments leaving the tracks.
In the aftermath of the incident, four railway staff members who were on duty have been temporarily removed from active service until investigations are completed.
Those suspended include the train driver, guard, assistant driver, and sub-guard.
Meanwhile, the Railway Trade Union Alliance (RTUA) alleged that the disciplinary action was taken to divert attention from management-level shortcomings within the railway sector.
RTUA Convenor Indika Dodangoda also stated that train drivers have decided to withdraw mechanically unsafe trains from operation and strictly comply with speed regulations.
