SINGAPORE: You’ve probably seen buses labelled 10A or 25M and wondered what the letters mean. Letters such as A, E, M and T are commonly used across bus services.
“A” usually refers to short-trip services that run during peak hours and start or end midway along a route to ease crowding.
“E” stands for express. These buses make fewer stops and often use expressways, offering faster journeys at slightly higher fares.
“M” indicates a partial loop. These buses turn back at a midpoint instead of completing the full route.
