Description

This entry is a description of the history of the Second Life Railroad ( SLRR ) on the Heterocera Atoll continent.

HISTORY

2005

The Second Life Railroad has its origins in early attempts by residents to provided automated travel around the mainland during a time when their were no direct teleports available. Some of the earliest examples - such as the "Telehopper" from Kissling and the Great Second Life Railway from Mocha to Purple - led to the first Linden-created trolley, operating from Luna to Dore via Nova Albion. As the first mainland expanded and Magellan Linden made additional discoveries beyond the founding of Nova Albion, roadways and other Protected Land Rights of Way (ROW) were crafted on the first continent, Sansara, but none were slated for rail use.

Eric, Nigel, and Michael Linden created most of the track and other structures, the rolling stock, most notably, the SLRR Commuter V1.2 car.

At this time, the track formed three unconnected tracks:
Bhaga^🖈 to Paranthrene, where the Clearwing / Paranthrene Transfer Station^🖈 was located;
Clearwing / Paranthrene Transfer Station^🖈 to an End Of Line (EOL) in Torva Station^🖈;
An EOL in Jubata Station^🖈 to the Tuliptree Station^🖈.

The Torva-Jubata Gap was a section that appeared to be intended for designation as Protected Land ROW, but by some mishap was sold to Residents. (In 2009 the ROW was reacquired by Linden Lab.)

The original three tracks were provided with five Resident-created stations, all named for the region in which they are located. These stations and their creators are:

• Achemon Station^🖈 - Pratyeka Muromachi
• Calleta Station^🖈 - nimrod Yaffle
• Neumoegen Station^🖈 - Fallingwater Cellardoor
• Obscure Station^🖈 - Jauani Wu
• Tuliptree Station^🖈 - Sam Portacerro

By experimentation and a few contacts with the original designers and implementers, members of the Second Life Railway Consortium (later renamed to the Virtual Railway Consortium) determined much of the functionality of the LL SLRR automated train system as created by Eric, Michael, and Nigel Linden. The scripted System Controller of the SLRR is located in the Right Of Way (ROW) maps on the office wall of the ANWR prim drilling rig^🖈. The SLRR Commuter V1.2 car ran as physical objects, 'steered' over the tracks by an invisible non-physical prim named Guide that the trains repeatedly collided with, thereby being directed back onto the correct course.

2006

In September of 2006, Nigel Linden announced a contest for Residents to design and build ten more SLRR stations, winning L$ prizes for their efforts, and completing the final builds by October 31st. From the 103 entries, the winning builders were:

• Bhaga Station^🖈 - Alazarin Mondrian
• Tenera Station^🖈 - Shawk Pertwee
• Aglia Station^🖈 - Elliot Eldrich
• Crenulate Station^🖈 - Donk Kongo
• Clearwing Station^🖈 - Ralph Doctorow
• Foxglove Station^🖈 - Midtown Bienenstrich
• Lunalis Station^🖈 - Lunalis SLRR Committee
• Spini Station^🖈 - Mordecai Nitschke
• Jubata Station^🖈 - Ilianexsi Sojourner
• Epirrhoe Station^🖈 - Ledje Gorky
• Zale Station^🖈 - Byron Curtis

These and other stations on the SLRR lines continued to be regularly served by the SLRR Commuter V1.2 car throughout 2006.

2007

In November, Michael Linden built the Vicina Quay^🖈, a large dock with a freighter ship floating nearby. A new SLRR-gauge track was laid connecting the Quay with Crumbi, creating the original Crumbi junction.

2008

On 1 April 2008, the Havok version 1 physics engine in SL was updated to Havok 4 gridwide. Changes in Havok itself, its interface with the LL simulator code, in the system tunings, and vehicle code of the upgrade caused the failure of most physical trains in SL, including the Commuter V1.2. Gradually, rolling stock creators began to make adjustment to their builds and scripts to accommodate the new operating conditions.

Linden Lab removed the problematic Commuter V1.2 automated train system and essentially abandoned the SLRR tracks.

The LDPW contracted a Mole to work on the SLRR system. This development resulted in a test on 31 December 2008 of new SLRR rolling stock scripts in two green Alco RS-3 locomotives created by Michael Linden. No version of this automated train has ever been put into service on the SLRR.

Over a period of two months, Rail Rally 2008 was hosted in two mainland regios - Schizura and Vicina. Sponsored by the Second Life Railway consortium, the Rally included two three day sessions and multiple events in the interim. The Rally brought together rail builders, scripters, merchants, train-spotting and -riding buffs, and a mix of Residents with rail and other transportation interests. The venue hosted an SLRR-gauge two region track loop with working signals and moving bridges.

There was a growing personal train industry in Second Life, with many builders and several very different approaches to train building. Proponents of LL automated trains lobbied to have the Lindens remove SLRR's solid center rail. Residents successfully fought this effort and the SLRR's solid center rail remains as a vital part of the SLRR's track standard.

Though not a part of the SLRR, rails were added to the Bay City mainland area. Many of them were essentially decorative, and for use on a non-physical trolley system down Route 66 in Bay City. A Bay City station was also constructed by Squishy Mole of the LDPW in Inner Harbor^🖈, but left unfinished at the opening of the Bay City area. It served only as a place to house the city's content package for Residents. Late in 2008, additional rails were laid from Grub Beach to Manyiminya^🖈in the Bay City area.

2009

By 2009 there was a thriving personal railroading industry in Second Life with a dozen or more active train builders. There was a reshuffling of the LDPW and consequently the priorities for the SLRR moved away from problematic "super-automated trains" on the SLRR Atoll tracks.

Early in 2009, the Resident-owned land in Sinica^🖈 where the SLRR should have been running since its inception was acquired, track was laid, and the Torva-Jubata Gap was closed.

Around the same time, a passing track in Sinica, between Torva and Jubata, was laid, a passing track was laid in Lunalis^🖈 and Fucosa Passing track^🖈, and slightly later, the Sinica Passing track^🖈 passing track mentioned above.

In late 2009 Sylvan Mole began the development of active switches for the SLRR. Multiple configurations have been tested to ensure compatibility with the widest possible range of existing Resident rolling stock designs. A switch design testbed^🖈 was constructed in Tussock.

On October 1st 2009 the SLRR Rail Group organized Rail Fest 2009. About 30 trains started at Tuliptree Station^🖈 and ran the entire Heterocera main line all the way to Bhaga^🖈. The after-party was held at Dougie Flossbergs railroad build in Yui Bon.

In late 2009 the track alignment near the Crumbi Transfer Station was modified. A bridging track was added in Tenera^🖈 to enable routing from that track over to the track heading out through Webworm. In Pawpaw, another bridging track^🖈 was laid to enable routing between the branch heading from Pawpaw to the Pavonia End of the Line^🖈, and the other from Pawpaw toward Tussock Junction. A trackbed extension from Tussock extended the SLRR up to Spangle. No center rail was installed, however, and many residents insisted that the LDPW finish this new track. Track in inner Harbor^🖈 to Manyiminya^🖈 in Bay City received a guide rail and buffer stops, and became a test rail for switches and crossings.

2010

Several residents began providing automated train, helicopter and ferry services around the SLRR, as well as giving out free trains and providing the ability to ride a train "on demand." The VRC began distributing a free open-source VRC Hobo Train to the public. The train's design was criticized by some residents for its griefing potential and a the VRC began distributing a different version of the free VRC Hobo Train. The free SLRR Crew Boat ride was created by Jer Straaf, which automatically rides approximately 39 regions pausing at all SLRR railheads.

VRC members bought land and made swaps with LL to enable: Expanding SLRR ROW at Pawpaw^🖈, adding that station and bridging track. Completing the LL ROW to a large Linden land area in Pyri^🖈.

Michael Linden reconfigured the Clearwing/Paranthrene Transfer Station^🖈 with the now-connected tracks passing on either side of the the station. Another passing track was laid in Triphosa^🖈, and a siding in Spangle. Several new stations and a railyard were also built by the LDPW:

• Crumbi Junction station^🖈 - Hyper Mole
• Dubia Station^🖈 - Crafty Mole
• Leafroller Station^🖈 - Abnor Mole
• Melanthia Station^🖈 - Myopic Mole
• Pawpaw Station^🖈 - Glamorous Mole
• Spangle Station^🖈 - Garden Mole
• Tussock Rail Yard^🖈 - Sylvan Mole

The LDPW began accepting requests for private resident rail connections to the SLRR, with connecting track being placed on a case-by-case basis. Several of these connections have been installed.

Road-grade crossing gate systems were installed at Mocis crossing^🖈, Cisthene crossing^🖈 and Oculea crossing^🖈 as part of the LDPW signal and switch project by Sylvan Mole.

The LDPW began building and placing new control signals signals on the SLRR. Several different designs have been fielded. This is controversial, however, because some residents see no need for control signals on the SLRR.

On August 15th the SLRR Rail Group held RAIL JAM 2010. Over 45 trains were counted along a route that took the participants from Bhaga Station^🖈 to Calleta "Hobo" Station^🖈. The event ended with a gathering at the Loco Motives track in XL City.

A test track in Fuchsia^🖈 was been build to show the switches and signals that where produced by Sylvan Mole.

Michael Linden, from the Linden Department of Public Works, organized a Railway Brown bag meeting to discuss the future of the SLRR and the standards of track, switches and signals. This took place on August 18th 2010.
