Railway repairs for Thailand’s northern line, earlier scheduled to be completed end of October, will be extended 30 days until November 30, the State Railway of Thailand (SRT) announced.
The suspended services cover a 300 km stretch between Sila-at station and Chiang Mai.
SRT Governor Prapat Chongsa-nguan said damage to sleepers and track were more serious than earlier expected and the SRT wanted to ensure complete safety to passengers.
He said heavy rains have delayed repairs and the SRT encountered a manpower shortage as many workers whose homes were flooded returned to their home towns.
A survey of the Northern line found that wooden sleepers at some spots were older than 50 years and tracks were quite worn.
