json2ttb is a external tool for Railway Operation Simulator which allows the user to speed up the creation of complex timetables.
The program works by parsing a user-written json file, which is then converted to a .ttb file which can be used in within ROS. The structure of the json file is in such a way that you define a service template, which can then be iterated upon and copied over several instances, which can have non-iterative references, descriptions, times and train data.
Key Features
- Allows for unusual repeats of services.
- Create templates of service data and use them for several services.
- Change the reference and description of single repeats.
- Allows for creating shuttles without using shuttle syntax.
- In most cases, quicker than writing timetables in ROS.
What json2ttb cannot do... (yet)
- Does not simplify writing individual services.
- No current support for the ROS repeats (e.g. R;30;2;2), repeats are done in a different way.
JSON Example
Below is a small excerpt of the json file which can be parsed by json2ttb. This example is taken from the timetable for Sheffield East.
