The Mass Rapid Transit Authority of Thailand (MRTA) has come up with a set of precautionary measures to prevent Covid-19 infections among subway passengers.
Pakapong Sirikantaramas, governor of the MRTA, said the Bangkok Expressway and Metro Plc, operators of the MRT's Blue Line and Purple Line, are asking passengers to wear face masks when they enter the system and keep them on throughout their journey.
The move comes as the Covid-19 pandemic shows no sign of abating, with soaring daily case numbers.
Under the measures, passengers can be held back and released in batches to reduce overcrowding in stations and on trains, Mr Pakapong said.
He stressed the need for physical distancing between passengers, with each sitting on every other seat and standing between 0.5-1 metre apart from others.
Passengers are also asked to avoid holding conversations while facing one another onboard trains or in stations.
They are also asked to use the Thai Chana QR Code system, and regularly use alcohol-based hand sanitisers provided at all stations, Mr Pakapong said.
