[Safety] Comparing the Gold, Red and Green Lines

Platform edge doors prevent passengers from falling off the platform edge onto the tracks. In my opinion, it should form a basic feature of all stations. However, while stations on the Gold and Green Lines have this safety component in place, those on the Red Line do not. While this may be due to a different service builder for each of the three lines, it raises the question whether they should all be required to comply with the same standards of the Ministry of Transport, which they are all operating under.Safety standards are essential and should be prioritised. In Japan these safety doors are not very prevalent compared to Thailand. It is a proof that we have outdone our friend in this respect. We would like to see all rapid transit stations in Thailand equipped with these doors. It means we are setting the bar high and always strive to assure safety comes first.
