The Fryske Line¹⁾ is an overground railway corridor constructed as first project by Moszyan Railways. The line was made to be a simple connection from the later-constructed Hylkemare station towards the Taipa area of the Let's Play Server, with a later plan to extend to Kallos. The line is known for using frisian naming conventions for its station names.

On December 12th, the first plan for the line was published, simply mentioned as the first stage of the Moszyan Railways Overground network. The plan showed a line going from Shuangmen Xuegui station (now Froastpoarte) to multiple stations on a horizontal line eastward. The map also featured a planned section of side-by-side running tracks between Moszyan Railways and the Lilac Light Rail.

On December 26th, the line officially recieved the name “Fryske Line”.

On January 28th, an updated plan map for the line was posted. It showed that the plan for the line had temporarily been shortened to ending at Hylkemare until a suitable solution could be found for the fact that bad planning initially had the line planned for at least a kilometer or two of over-sea travel.

On February 6th and 8th, it was announced that an originally unplanned new station was to be constructed on the line, going by the name De Marren.²⁾ After that, the plan for a station over the lake in the yellowstone biome was dropped.

On February 12th, a new extension was added to the plan, connecting the relatively out-of-reach line to the Kallos area. Connecting directly to Kallos station was not impossible, but it was decided that it would be for the better to put the terminus in the open field next to the Royal Park light rail station, precisely where another line already had plans to connect. The end of the bridge was planned to have a replica of Spijkenisse's Metro Rail Whale statue, known for the crash in 2020 where a RET Metro train ended up being saved from falling by the massive tail.

On February 14th, “Station 19” was revealed to receive the name Ridgecrest. The frisian name for this station would end up being Rykkam.

On May 12th, all tracks between the two terminus stations were finished, and the line started running a shorter service between Kallos Royal Park and Āoraki North. The depot was moved to Royal Park, and the temporary 2-car siding at Hylkemare was removed.

On May 22nd, construction of Rykkam's “temporary station design”, probably to stay as a permanent structure due to its castle wall design, was finished. This meant that all stations on the line had now been completed and were just awaiting connection.

• The Fryske Line may be the first to use frisian naming conventions, but not the first to use dutch naming conventions. This is due to two stations north of spawn carrying the names Zuidbaai and Zuidbaai Centraal. One could argue however, that these naming conventions are tied closer to afrikaans than dutch, as the dutch rarely use the term “baai”.
• Rykkam is the only station to have both the english and frisian name on the system map, as its the only interchange station on the line that did not already have a chinese name.
