Poly couple run over by train were drunk

This news was happen on Aug 8 last year
Both of the students from Republic Polytechnic were dead. Due to the Malayan Railway train was unable to stop in time. A coroner’s court recently found out that the pair were too drunk to get away from the path of the oncoming train. The train driver had just taken the train, and was moving at 70kmh, around a bend along the Bukit Timah bridge when his assistant spotted something on the truck about 30m ahead. They sounded the horn three or four times. It was only when the train was 10m away that they realised there were two people on the track facing each other. The driver applied the emergency brake, but it was too late as the train needed 50m to stop completely. Their friends said that there is no reason for them to commit suicide and neither were there any documents or messages to indicate they were troubled or wanted to kill themselves.

This article appears to me because I wondering is what train run over them?? Is MRT or others.
I would like to ask the writer that will there any action to be done example like they will not let people to easy accessible to the place and will put more warning signs?
If I am in-charge I will try to increase more barriers to the place.
