The Transportation Safety Board (TSB) says its investigation into a train derailment in Manitoba on December 31st will be limited in scope.

A Via Rail train running between Churchill and Winnipeg was going about 100 kilometres an hour when several cars derailed near Gladstone.

The TSB says it is doing a Class 4 investigation, which means the final report could contain limited analysis but will not have findings or recommendations.

Class 4 investigations are usually completed within 220 days, says the federal agency.
