Business Times reported that an email had been sent to all employees on Monday notifying them of changes at the management level.

The report quoted sources as saying that the board had ordered an internal investigation. “We can’t disclose anything more until the investigation is completed.”

Malayan Railway was turned into a government-owned company Keretapi Tanah Melayu Bhd in 1992 and has debts of more than RM2.5 billion.

Last week the railway suffered a disruption of the popular ETS services during the Deepavali weekend when several wagons of cargo train went off the rails near Batu Gajah blocking one of the tracks on the trunk north-south line.

Work on extending the double-track line from Gemas to Johor Baru will begin next month and is expected to be completed by 2020.
