According to Jang Chol Su, an office head at the Ministry of Railways, the ministry's transport plan for March was over-fulfilled and tens of thousands more tons of freight than schedule were carried away in the first six days of April.

Meanwhile, the Kim Jong Thae Electric Locomotive Complex made innovations in the production of locomotives and the Pyongyang Passenger and Freight Car Corps finished the painting of trains in only 40-odd days after the start of the ongoing 70-day campaign.
