Density Loop

Density Loop is a rail loop around the Sea of Density built and governed by FERRA. It goes through 21 stops, with three connections to Cenrail and other FERRA lines.

Early Stages

The plan to create a loop around the Sea of Density (then unnamed) was conceived on the same date as FERRA was formed, 23 April 2025. The original plan considered going through Martinus' Territories and taking a stop at B’hiy’aj Dchâjâ. Both considerations were later rejected.

Since T'anshilebs was already in the process of constructing its underground rail system, it was integrated into the plans of the loop.

Construction

It is estimated that the Density Loop has consumed around X stacks of rails, Y stacks of powered rails, and Z stacks of redstone torches, as well as C stacks of blue wool, and in fully-enclosed segments, B stacks of tuff.

Construction began with the segment of rail from Ḿaro-Heki to Perhyh (then Rainsten), mined by Dragonfly. It continued to Green Transitional, Syfa, then from Ḿaro-Heki to Kiakus'a. In the meantime, Wánade portion of the rails was being constructed. On the 29 May 2025, the tunnel from Syfa to Yäzka was opened. On the 30 May 2025, Bä Daras was connected with Alk’emit’at, and in evening hours of that day, the loop became functionally complete.
