What is a service pattern?

• A. The designed sequence of stops and service levels along a route.
• B. The maximum operating speed on a line.
• C. The color scheme of station signs.
• D. The schedule for maintenance windows.

Answer: (A)

A service pattern describes how trains operate along a route in terms of where they stop and what level of service they provide. It defines which stations are served, the order in which trains run, and whether a train is local (stops at most stations) or expresses (skips some stations), including how often service runs at different times of day. This pattern can vary by time of day or day of the week to match demand and track constraints. It’s not about how fast trains can go (maximum speed), nor about the colors or branding of signs, nor about when maintenance happens. Those aspects cover performance, appearance, or maintenance planning, not the actual way service is delivered along the route.
