When we select stations to define a rail line, only one way travel is defined. The returning train always selects the shortest path. In this example Vienna West is in the station list, the return path is not defined, so the train will return through Vienna Ost, the shorter path.
To make sure the returning train follows the same route, specify the stations for the returning train too.
To increase profit (or reduce losses) you can make adjustments to your empire.
If the train frequently leaves a station without freight, set the minimum number of wagons to 4 for that station. The train will wait at the station until at least 4 wagons are loaded. Add a track to the station for the train to wait on, so other trans can also use the station.
If you set the other end of the line with the same restriction, it is possible, that the train will very rarely return to this station.
Assign the lines to the tracks of the station. By default trains select the shortest route using the same track of the station.
Error: MUI: The data grid component requires all rows to have a unique
idproperty.
Alternatively, you can use thegetRowIdprop to specify a custom id for each row.
A row was provided without id in the rows prop:
The Material UI Data Grid needs to have a unique ID to identify the rows.
To specify the column with the unique numbers, use the getRowId property.

rows={rows}
getRowId={(row) => row.MY_ID_COLUMN}

If only one main line runs through your railway station, but the traffic is very high, build a station with 8 tracks. To allow trains to use any track of the station, we could use 8 track gridirons, but those require long parallel tracks. We can use four 2 track gridirons, and combine the tracks with curved tracks in a much smaller footprint. We will also add an 8 track supply tower to refill trains on all tracks.
To prepare the site for the construction,
Remix vastly simplifies access to backend processes by auto-generating all API calls between the browser and the web server. We only need to create the “loader()” function to get data from the server and the “action()” function to submit a form.
For security reasons the Node.js web application environment variables are not available in the browser, as those usually contain sensitive information, like database access credentials.
The “loader()” function can read and expose selected environment variables to the browser via the API.
Make sure you have created the /app/routes/_footer.tsx file to display the name of the environment. See Footer in the previous post.
import { LoaderArgs, json} from "@remix-run/node";
import { useLoaderData } from "@remix-run/react";
export default function Index() {

const { environment} = useLoaderData<typeof loader>() || {} ;

npm install -g cross-envTo connect a branch line to a main line at a railway station in Railway Empire 2, create a station with four platforms. In the example below the mainline is on the left side on tracks #1 and #2, the branch line arrives to tracks #3 and #4 at the bottom from the right.
To allow any train to reach any track, we will place a four track gridiron where the branch line arrives.
At the top we will connect tracks #3 and #4 to the main line, so the branch line trains can continue on the main line, and main line trains on the branch line.
We will place two separate 2 tracks gridirons, one on tracks #1 and #2, and another on tracks #3 and #4. A four track gridiron would also work, but it requites twice as long parallel tracks.
