OSRR

OSRR or OpenSim Railroad is set of rail SLRR-compatible standards for OpenSim, designed by Z. Unlike SLRR, these standards promotes the use of mesh in contrast to sculpts and prims. Like SLRR, it's open source starter kits that provide reference for alternative railroads.

Concept & Inception
Z has fiddled the idea of trains since his return to Second Life in 2009. His first major projects consisted of heavily prim-based double- and single-deck passenger cars where he tried to use as less prims as possible while achieving the design he wanted. At this time, he was unaware of SLRR.

Sometime during early 2010s, Z discovered SLRR. He purchased a wide veriarity of locomotives and sets. However, since SLRR was made during a time during a time when prims and early sculpts was more common along with the use of outdated scripting techiqes that make for painful sim crossings. While OpenSim has larger regions, prims are still common on the Hypergrid and there is no railroad standard.

Originally meant to be an alternative open source simply track and wheel set, Z has decided to attempt to provide a railroad standard for OpenSim based around mesh.

Prototypes
Due to the grandfathered L$50 stipend, prototypes are currently being designed and tested on Z's Kit/Cairo account. This includes proper track gauging and testing on both OSRR and SLRR tracks. Z is also designing an open source DMU railcar with sleeping, food, and possible bath accommodations. the bogies won't hint to the locomotive power.

Relation with the Demin canon
Since Z is still working on the details in filming and capturing, the story is not as set in stone with Demin. The current story centers on Kit and Cairo on a yacht but may shift towards to Zack, Kit, and Cairo on the railroad with the mentioned DMU railcar, due to the short and long-term expense being far lower and SLRR being well documented.
