Gentek Rail System

These are general ideas for a future rail system.

Standards

• Track gauge (inner <-> inner) = 1.96 m (to allow for SLRR rail compatibility in the far future, although SLRR tracks alone will be incompatible with the scripts, see "SLRR compatibility")
• Minimum vertical clearance = 5.5 m
• Minimum horizontal clearance = 4.0 m on straight sections, 5.5 m on curved sections (minimum)
• General car length, wheel to wheel = 12.5 m
• General car length, end to end = 16.5 m

Guides

• Straight
• Stop buffer (reversible)
  • Instantly stops train to prevent derailment
• Switch left (switchable, requires 2 connections in one direction)
• Switch right (switchable, requires 2 connections in one direction)

Sensors

note: sensors will require 2 pieces to detect movement direction

• Block delimiter
  • Will require detection of multiple cars and constantly ping for their presence
  • Also allows for trip stop e-brake if connected to a signal showing a stop indication
• Switch alignment
  • Aligns connected switch for train merging onto single track

Train automation

Automated systems will have to be custom-designed, it is prohibitively complex to make automated train control devices (think UR but 10x as complex); nobody will figure it out
Ideally the engines could be remote controlled in a way to start up and assign routes through various switches to reach an endpoint (since freight trains would be stored either in a yard or in a "magic depot" instead of running continuously) but this is obviously not a consumer-friendly setup - continuously automated trains, e.g. Lionheart passenger service, may be an option

Rolling stock

• Standard Boxcar
  • many different themes (won't list here)
• Standard Tanker
  • some different themes (to be done)
• Standard Flatcar
  • not really any themes to make, but has different cargo
• Standard Hopper
  • themes yes indeedy
• Standard passenger car
  • could make a lot of themes for this
• Standard mail/baggage car
  • yep more themes sure thing
• Russian-styled boxcab engine
• US-styled hood-unit freight engine
• F40PH/P42DC passenger service engine
• Electric standalone passenger unit (metro/subway)
• Maybe a steam engine, would be popular with VRC types

SLRR compatibility

Problems with SLRR compatibility:

• No standard for overhead/wayside clearance
• Guide prims are too close together to have trains travel at speed and calculate movement directions
• Curve radius is too small (turns too quickly) in some locations, which might fuck things up at high speeds
• Switch designs are pretty shitty
• No signalling, which will be a critical aspect of the system (particularly for automated trains)
• Public SLRR lines have no control system or prompt maintenance and tier for trackside yards/depots would be too expensive
  • Privatized SLRR compatibility would be theoretically possible, but it would be easier for them to just set up additional guide pieces

Problem pessimist checklist

Works

• Crossing sims with keyframed movement
• moving_end to detect when movement stops

Doesn't works

• (nothing yet)

Untested

• Sensor across sim borders
• Curve system feasibility
• Chained communications down entire consist when car(s) crossing border
• Movement determination in each car
