Night service (public transport)

Another common way to distinguish night services from their daytime counterparts is dark-colored line numbers.

Local bus frequencies during late night times (defined as 1 a.m. – 5 a.m.) are required to operate at least every 60 minutes.

[1] Because of much longer intervals between services than during the day, night routes often offer guaranteed transfers to other lines or transit modes (such as regional and intercity rail).

To ease planning, many cities use a central hub where all lines converge at a specific time.
