Don't ask me why I never hotlinked it.
Today they seal off every track already, any one go inside is consider as illegal trespasser, shoot on sight, and also what ever trek you go, make sure it is the railway track, not our MRT tracks, once you get hit by MRT, the disruption is going to cause alot of people problem.
