ULink

uLink is the main rapid transit system serving the Underwater Islands, consisting of 2 lines and 15 stations. The system originally opened in April 2020, before being extended north and west in late 2020 and even further west in June 2021.

History
When Underwater Islands Airport was under construction, the airport’s operator, Samuelian Airports proved that there were problems on how to connect the airport to the city. Underwater Islands therefore decided to build a rapid transit system to connect the airport and at the same time, better serve the city with transportation. This project would be named the Space Needle High Speed Line. In April 2020, the section of track between Space Needle and Luxury Island began trial runs, with the entire line to Airport opening later that month.

Late 2020 saw another rapid expansion to the system. In November 2020, two infill stations were added at Botswana and Draconian Pond, serving northbound trains. Another infill station was opened at Botswana New Street at the same time to serve southbound trains. In December 2020, the line was extended north to Diagon Alley, adding 4 new stations. The Space Needle High Speed Line was renamed to the Space Needle Line at the same time.

On June 1, 2021, management of the rapid transit line was switched, and a renaming system took place. The original line was split into two lines, with Line 1 running from the Airport to Oriental Bay and Line 2 running from Botswana to Diagon Alley.

Construction on a new Crackton Extension project also began and opened in phases. On June 3rd, Line 2 was extended west to Crackton, serving the new minigame complex there. Line 1 service to Oriental Bay was also reinstated, before it was extended north to Glacier Parkway on June 12th.

On August 4, 2021, it was leaked that an infill station between Botswana New Street and Underwater was approved by uTransit District officials, with construction to begin later that month.

Network
Since June 2021, the uLink has been using numbered lines to differentiate each services, each line also marked by colours to further distinguish them. Lines 1 and 2 share stations in the Central area, between Space Needle and Oriental Bay. One more line, Line 3, will open in August 2021 using energy-efficient detector rail technology. Line 4 will also use this technology and will open later that year.
