A Starlink satellite train is a line of newly launched Starlink satellites seen moving together across the night sky.
Starlink is SpaceX's internet network, based on thousands of small satellites in low Earth orbit, at an altitude of about 550 kilometers (approximately 340 miles). The term "satellite train" describes groups of recently launched satellites that move together across the sky; under suitable conditions, they can be seen with the naked eye as a string of lights.
The term refers to the appearance of the satellites in the sky, but Starlink satellites are also used to provide internet connectivity on the go. According to SpaceX, the service is designed to operate in moving vehicles and under harsh weather conditions. A 2026 report described an experiment in Latvia where a Starlink terminal was installed on a train to test internet connectivity during travel.
The company presents its mobility service as fast and reliable internet while in motion, but the connection depends on an open line of sight to the satellites. A report on communication issues on trains in Israel noted that tunnels still block the signal; satellite coverage above ground does not guarantee reception inside them.

Not necessarily: tunnels can block the signal, even when there is satellite coverage above ground.
