The Raven's Peak Sky Rail was a series of fast-moving sky rails suspended from rail lines on the planet Eriadu. It was used during the Imperial Era to access Raven's Peak, an elite fortified compound belonging to Wilhuff Tarkin. The sky rails of the Raven's Peak Rail Line consisted of two crate-shaped cars on parallel tracks, which shuffled troops back and forth. Around 18 BBY, Clone Force 99 infiltrated Raven's Peak through the sky rail, after disabling its sensor.
The Raven's Peak sky rail consisted of a network of fast-moving twin-car sky trains that moved along two reinforced rail lines suspended from the mountains around the Raven's Peak fortress on the planet Eriadu. The trains were connected to the track via a complex assembly of powered interlocking gears that rotated, thus moving the trains along the sky line. A number of maintenance stations were located on the sky line's support pylons to allow for easy access to the line's computer.
The rail line began on a small base station facility on the lower hills of the mountain, where two observation posts were also located overlooking the valley below. From there, the line was mostly suspended on the air until it reached a station in the hangar level of the fortress itself, although in some spots it came close to nearby mountaintops. These parts of the line were equipped with military-grade perimeter sensors that were able to detect organic movement nearby in order to deter potential hijackers.
The Raven's Peak Sky Rail first appeared in the fifteenth episode of the second season of the animated television series Star Wars: The Bad Batch, "The Summit." It later appeared in the sixteenth and final episode of the season, "Plan 99." Both episodes premiered on Disney+ on March 29, 2023.
