The extra 30-day suspension of services for the 300-kilometre stretch from Sila-at Station in Uttaradit to Chiang Mai was due to worse-than-expected damage to sleepers and tracks, Prapat said. He said the SRT wanted to ensure the track was 100 per cent safe for passengers before it was reopened.
Flooding had also aggravated delays, as many SRT employees needed to return to their homes urgently to deal with rising floodwater, he said.
