Panat Mongkolrit, a railway official at the Nakhon Lampang train station said that work to retrieve the Chiangmai-Bangkok train derailed on Saturday evening has not yet finished but is expected to be completed by today to clear the route for northbound trains.
Train service from Bangkok could still run to the Nakhon Lampang station on Sunday morning with the station providing air-conditioned buses to take passengers on to Chiang Mai.
No one was wounded in the incident, as there were no passengers on the train when it derailed. The cause of the accident is still unknown.
Yutthana Thapcharoen, governor of the State Railway of Thailand (SRT), inspected the area where the train derailed on Sunday. He affirmed that train services were expected to resume by 1 am on Monday.
An investigation is underway to find the cause of the mishap, which could be from worn out or deformed rail tracks, possibly caused by high temperatures. A probe will also be conducted to determine the riding speed at the time of the accident, the governor said.
