Railway Operation Simulator Toolkit
RailOSTools provides a set of tools for working with Railway Operation Simulator program files. The repository contains various API language implementations to provide access to Railway Operation Simulator session and file properties
All command line tools are available under the parent railostools command:
$ railostools
Usage: railostools [OPTIONS] COMMAND [ARGS]...
Python based utilities for Railway Operation Simulator
Options:
--debug / --normal Run in debug mode
--help Show this message and exit.
Commands:
ttb2json Extract RailOS timetable file to jsonThe command ttb2json converts a .ttb file to a JSON file containing the metadata for the services.
This allows for easier data interpretation within other projects.
$ railostools ttb2json --help
Usage: railostools ttb2json [OPTIONS] TTB_FILE
Extract RailOS timetable file to json
Options:
--output TEXT JSON output file
--help Show this message and exit.The command rly2json converts a .rly file to a JSON file containing the metadata for route elements.
This allows for easier data interpretation within other projects.
$ railostools rly2json --help
Usage: railostools rly2json [OPTIONS] RLY_FILE
Extract RailOS railway file to json
Options:
--output TEXT JSON output file
--help Show this message and exit.Features within railostools can also be accessed via the dedicated Python API.

my_parser.dump('Antwerpen_Centraal.json')The performance log parsing module can asynchronously monitor the Railway Operation Simulator logs directory extracting
contents which can then be processed by applications live. The Monitor class is designed to only retrieve data when
it has been confirmed by file modification time that the log has been updated. These times are also used to fetch the
latest log during running. The class uses the Python asyncio library.
import railostools.performance
import asyncio
from railostools.performance import Monitor
ROS_LOG_DIR = 'C:\\Program Files (x86)\\RailwayOperationSimulator\\Railway\\Performance\ logs'
# Create a new monitor pointing to the RailOS log directory
my_monitor = Monitor(ROS_LOG_DIR)
# Create a listener function which will just print the data
# MUST have 'monitor' as an argument, this is the monitor instance
async def listener(monitor: railostools.performance.Monitor, user_name: str) -> None:
# Run until the monitor stops
while monitor.running:
print(f"Running for user '{user_name}'")
print(monitor.data)
await asyncio.sleep(10)
# Attach listener function to the async loop of the monitor
# arguments are given as a dictionary
my_monitor.exec_in_parallel(listener, {'user_name': 'John'})
# Finally run the monitor
my_monitor.run()
