THEME: Peak
A typical peak period scenario in an MRT station includes heavy boarding and alighting activities, crowded trains despite decent frequencies, especially in interchange stations. Travel time is also usually longer than the what signboards in platforms stipulate given the huge crowd and other factors like train bunching.
