Using https://github.com/railnova/osrm-train-profile and with the help of some LLM, I got this working:

I have stopped integrating it into the UI.js, such that I can update more easily. I now use import and export functions instead. And yes the train icon interpolates between the stop positions! The train data API I am running locally only includes SNCB data. |

Now using https://docs.irail.be/ instead of my own scraper because the SNCBs website is using Cloudflare protection. |

Instead of showing the tags, I would like to show icons, according to the YAML configurations. But I don't quite understand where the conversion is taking place and how I can replicate it.... At first I thought I could just convert in JS using the YAML, but when the map is loaded, the YAML files are not available to the JS. @hiddewie Is there something obvious I am not seeing? |

During the import process, the YAML is converted into a (huge) database view which does the matching of tags to the features (icons) you see on the map. The map then renders the icon by splitting and composing it on the map to form the signal you actually see on the map (possibly stacking multiple on top of each other). |

This little update is probably more for here, but since all of the tools shown above are basically useful for it as well, I'll just add it here:
(In styles.mjs (file type not supported): 'icon-rotation-alignment': 'map' and 'icon-pitch-alignment': 'viewport' for the signal medium and high) |

Incredible work, this is super nice! For the in-transit mode we could already merge the pitching and hiding of signals of the opposite direction. |

Little notes:
Let me know if I can help with something. Do you plan on adding the 3D buildings as well when introducing pitching? |

I am starting some integration work based on your work in #946. At this moment I don't plan to support 3D buildings, because the OpenRailwayMap itself does not contain any 3D buildings. But maybe we could support it for background maps that have the information. Similar to supporting hills and mountains in 3D. |

Exciting news! #I don't plan to support 3D buildings https://maplibre.org/maplibre-gl-js/docs/examples/display-buildings-in-3d/ |

I mean that currently there are no buildings imported into the OpenRailwayMap, except signal boxes. To display buildings using OpenRailwayMap data, "normal" buildings in for example cities would need to be imported in order to be displayed on the map. At the moment I don't plan on doing that because non-railway related buildings are a huge amount of data worldwide and are not related to railway data in OpenStreetMap. But like stated above, if a background map has building data, maybe 3D buildings on the background map or on the terrain could be enabled. I did not look into this yet. |

Here's a little video after I added tracking. Next: see what's on our route in the next 1500m https://www.youtube.com/watch?v=xJOv0l8QGGY @hiddewie You're going to really like this! |

One big issue I have is that I can only access the "features" from the layer I'm in, so I can only get the symbols from the layer I am on. So signals in train-protection, level crossing in infrastructure, speed signs in speed etc. |

I tried to solve it by creating a style that combines all layers. |

Currently trying a Dijkstra to find points x metres from a defined point (here intersection points of the line A-B). Probably not useful for many, but extremely useful for me! Will try to implement in ORM later.

Hey!
Perhaps it can be considered to add some basic geometry tools into the front-end.
Or even better something similar to https://signal.eu.org/osm/#locs=48.690960,6.295166;53.443899,6.725006
It could be used to calculate distances between two track elements, a geographic location and track element or calculate a location x-distance from an element/location. It also allows us to extrapolate track KMs.
The routing part an sich is also very interesting and would fit greatly into an ORM-toolbox. Currently it can take electrification, gauge and (non-)HSL into account. It could be considered to take train protection into account too.
It could also be groundworks for an in-transit mode, which with this could be generalised, i.e. not requiring the use of preprogramed OSM rail relations. Instead it could take the current location and destination into account, with the possibility of adding intermediate locations.
