Hi!

Over the past years I have been working on a fork of the OpenRailwayMap.

The announcement can be found on the OpenRailwayMap mailing list and on the OpenStreetMap community forum.

The fork has several features, and is actively being developed by me and several more contributors:

  • Vector-based data: the map is interactive with e.g. hover and popup showing data details.
  • Map style improvements: station size, state of lines and statons, signal support for many new countries.
  • Visual UI improvements like: configurable background map, map settings and dark mode.
  • Additional layers: loading gauge and track class.
  • Daily data updates for the entire planet.
  • OpenHistoricalMap integration for historical railway infrastructure.

At the moment the fork is hosted on https://openrailwaymap.app using Fly.io. This is purely practical, it could be hosted anywhere else.

This pull request is a starter to discuss:

  • Can we integrate the fork into the Github OpenRailwayMap organization
  • Can we publish the fork on the domain openrailwaymap.org?

These are open questions, any response is appreciated!

This keeps the tile sources consistent (currently it is a mix of views
and functions), and allows using the 'id' column of a layer as ID,
without promoting it client-side.

Changing the fields of a single tile view is also possible by redefining
the tile function (and comment), without further changing the Martin
configuration or even restarting the Martin container.
Fixes #605 

Implements:

- ETCS block markers
- TVM/CBTC block markers
- Cab Shunt Entry block markers
- Entry, Exit, and Warning of entry into cab signalling
    - Directional arrows for the above (left and right only)
- Block marker absolute/passable plates

Drawn from the relevant RSSB standards.

## Potential testing locations

| Location | What's there |
| --------- | -------------- |
| Aberystwyth | ETCS block markers, cab signalling entry (2) |
| Dovey Junction | ETCS block markers |
| Tywyn | ETCS block markers, shunt entry block markers, cab signalling
entry |
| Barmouth | ETCS block markers, shunt entry block markers, cab
signalling entry |
| Harlech | ETCS block markers, shunt entry block markers |

Note: At Barmouth the crossing signal (white/red flashing light) should
be above the ETCS block marker at the UP end of the platforms.

TMACS is another australian system
([enwiki](https://en.wikipedia.org/wiki/Train_Management_and_Control_System)
| [osmwiki](https://osm.wiki/Key:railway:tmacs)). Just like ATMS (#546),
it uses GPS instead of Balises.


To avoid a colour clash, i've used `#ffcc00`. This is a list of every
colour used in Australia:

* `#006eff` ETCS
* `#cc0052` CBTC
* `#43b54d` ATMS
* `#884400` TWC
* `#ffc0cb` TPWS
* `#ffcc00` TMACS 🆕

I added italian square main, distant and combined signal icons. They are
used where signals are placed on the right of the track they reference
to. I don't know how to test the updates to
signals_railway_signals.yaml. I hope for the best.

I proposed to split italian AVA.svg and AVV.svg substitute signal icons
from primary signals they can be referenced to. I don't know if the this
issue can be implemented: have a look to comments i wrote in
signals_railway_signals.yaml.

Note that the 2 light_rail stop positions are tagged as `train = yes`,
so they are rendered orange (for train) instead of green (light rail).

…gnal query (#659)

Split off from
#657 to make that
PR a bit smaller.

Part of #484, this improves performance importing signals.

This pull request splits off the *direction* and *features* (*icons*)
into separate views.

During tile rendering, the `signals` table is joined with the direction
and feature views to determine the signal direction and features for map
display.
This PR adds all light signals for New South Wales (Australia), except
`main` and `distant`, because those two are more complicated, like [the
italian
system](#639).

See [the osmwiki
page](https://osm.wiki/Australian_Tagging_Guidelines/Railway_Signals#NSW)
for details.

In Australia, there can be up to 6 `train_protection` signals on a
single pole
([example](https://wiki.openstreetmap.org/wiki/File:NSW_Railway_Signal_full_example.jpg)),
so we need to increase the limit from 5 to 6.

After #642 CI
failed in #642
because of missing merge checks for import tests.
Selecting the correct radio button from user configuration for the
station labels in the settings UI was using the incorrect variable.
Part of #545 

Requires decoupling the icon from the signal "feature".

Goal: instead of duplicating the same signal features because they have
similar tags but need different icons:
```yaml
  - description: 1ª categoria quadro (Avvio & Avanzamento) (1 light)
    country: IT
    icon:
      match: 'railway:signal:main:states'
      cases:
        - { any: ['(Y)', 'Y'], value: 'it/main-s-1v-AVV-AVA-Y' }
        - { exact: 'G', value: 'it/main-s-1v-AVV-AVA-G' }
      default: 'it/main-s-1v-AVV-AVA-R'
    tags:
      - { tag: 'railway:signal:main', value: 'IT:1V' }
      - { tag: 'railway:signal:main:form', value: 'light' }
      - { tag: 'railway:signal:main:shape', value: 'square' }
      - { tag: 'railway:signal:main:substitute_signal', all: ['IT:AVA', 'IT:AVV'] }

  - description: 1ª categoria quadro (Avanzamento) (1 light)
    country: IT
    icon:
      match: 'railway:signal:main:states'
      cases:
        - { any: ['(Y)', 'Y'], value: 'it/main-s-1v-AVA-Y' }
        - { exact: 'G', value: 'it/main-s-1v-AVA-G' }
      default: 'it/main-s-1v-AVA-R'
    tags:
      - { tag: 'railway:signal:main', value: 'IT:1V' }
      - { tag: 'railway:signal:main:form', value: 'light' }
      - { tag: 'railway:signal:main:shape', value: 'square' }
      - { tag: 'railway:signal:main:substitute_signal', value: 'IT:AVA' }
```
instead, allow multiple icons, composed with each other:
```yaml
  - description: 1ª categoria quadro (1 light)
    country: IT
    icon:
      - default: 'it/main-1v-s'
      - match: 'railway:signal:main:states'
        cases:
          - { any: ['(Y)', 'Y'], value: 'it/1v-Y' }
          - { exact: 'G', value: 'it/1v-G' }
          - { exact: 'R', value: 'it/1v-R' }
      - match: 'railway:signal:main:substitute_signal'
        cases:
          - { all: ['IT:AVA', 'IT:AVV'], value: 'it/AVV-AVA', description: 'Avvio & Avanzamento' }
          - { exact: 'IT:AVA', value: 'it/AVA', description: 'Avanzamento' }
          - { exact: 'IT:AVV', value: 'it/AVV', description: 'Avvio' }
    tags:
      - { tag: 'railway:signal:main', value: 'IT:1V' }
      - { tag: 'railway:signal:main:form', value: 'light' }
      - { tag: 'railway:signal:main:shape', value: 'square' }
```
(this example is only combining 2 signals, the Italian signals will have
more variants composed together)

For a full example, see
#639 which has
huge duplication because of the large variety in tagging. (A good thing,
but currently the YAML configuration does not support such use cases
well.)

This requires changes in many different places:
- [x] UI icon map rendering #656
- [x] Icon size determination
- [x] Signal feature SQL
- [x] YAML signal configuration
- [x] Taginfo
- [x] JOSM preset
- [x] Documentation
- [x] Signal feature performance
- [x] Duplicated features in popup
- [x] Make offsets work
- [x] Split off commit
66a7eae
into separate PR --> #659
Followup on #657

Features with multiple icons did not output their icon height correctly
for non-center-positioned icons.

Now the feature icon height is calculated as
```
max(max(centered) + sum(top_bottom), left_right)
```
with centered the height of centered icons, `top_bottom` the height of
the top/bottom positioned icons, and `left_right` the left/right
positioned icons.

Recently, I've surveyed Warsaw Central with its new railway signalling
and having discussed at forum on Skyscrapercity
(https://www.skyscrapercity.com/threads/warszawa-warszawski-w%C4%99ze%C5%82-kolejowy.979536/page-364?post_id=195487518#post-195487518)
I've realised that a certain type of semaphore hadn't existed.

It's the case when semaphore has 5 cells
(green-yellow-red-yellow-white), but the 2-cell signals contain only
yellow lights, no green-yellow (as it's currently implied by code).
Thus, I've made it possible to render properly currently 2 semaphores
(G1C and G2C, https://www.openstreetmap.org/node/12021271222 and
https://www.openstreetmap.org/node respectively) at Warsaw Central

Analysis in
#662 (comment)

This pull request uses the total rail length of all railway lines within
a yard, to assign a measure of importance to the yard.

This is similar to how platforms and railway routes assign importance to
passenger railway stations.

The current thresholds are set at >= 7200 meters of rail is a large
yard, >= 750 meters of rail is a normal yard, and all others are small.

I renamed everything *route count* to *importance*, because stations and
yards each get a (scaled) importance which can be compared (e.g. in API
search results).
Closes #555

## Goal

Improve the distribution of stations on the map for lower zoom levels,
worldwide, without cluttering the map with too many stations.

## Implementation and documentation

Method: *Discrete Isolation* to provide a measure of local importance of
a station, compared to a global importance.

See:
- https://osm2pgsql.org/doc/manual.html#strategy-discrete-isolation
-
https://blog.jochentopf.com/2022-12-19-selecting-settlements-to-display.html
- https://dx.doi.org/10.1007/s42489-021-00079-y

## Changes

The *Discrete Isolation* implementation of Osm2pgsql is used. This is
experimental but works fine.

After the station importance has been determined by the number of routes
or rail length (for yards), the discrete isolation algorithm is ran to
determine the discrete isolation column values for each station.

The discrete isolation are used to filter zooms 4 until 7, instead of
just the station importance values. The result is that huge stations
close together (e.g. in the same city) do not all show on the map in the
same location, because locally one of the stations will be the most
important.

Worldwide this makes a difference because many stations do not have many
routes like the large European stations, but do have more routes tagged
than other stations in the area, making them locally more important.

Furthermore, the requirement to have a railway reference has been
removed. For non-European stations, railway references are often not
tagged, which removed them from the map for the low zoom levels.

Zooms 3 and lower are unchanged and show no stations.

Zoom 4 shows medium and large stations without their references/names,
filtered by local importance for zoom 4.

Zoom 5 shows medium and large stations, filtered by local importance for
zoom 5.

Zoom 6 shows medium and large stations, filtered by local importance for
zoom 6.

Zoom 7 shows all stations, filtered by local importance for zoom 7, but
no references/names for small stations.

Zoom 8 and higher shows all stations.

## Future

Stations should not be rendered for low zooms if they are not on
main/branch lines, and for non-train modalities. There is much missing
tagging in some regions of the world. See e.g.
#663.

With more stop areas and routes tagged, the importance of a station is
clearer to determine worldwide. Some future tweaking of the discrete
isolation output values might be needed.

hiddewie and others added 30 commits May 22, 2026 22:45
Followup from #960 which put the argument of the station name for high
zooms in the operator layer in the wrong place.
Simplify the style expressions for rendering the guage coloring with the
`interpolate-hcl` expression.

Move the generation of railway line labels for the infrastructure,
electrification and gauge layers to the map style instead of the
database.

The speed label is an exception, it is generated with complex logic
during data import.

Additionally, the reference and name are not output in the low zoom
tiles anymore, because there is no use for it in the tile rendering.

This adds most railway signals of Luxembourg.

The documentation can be found at
https://wiki.openstreetmap.org/wiki/OpenRailwayMap/Tagging_in_Luxembourg

- This includes every signal in Luxembourg currently tagged in OSM
except for tram and foreign signals.
- Signals RF6 and RF13 are included as symbols, but not yet implemented
as signal features, as I want to wait for a new suitable signal category
(#972).
- Some other signals not yet tagged in OSM are still missing which I
will add when encountering them in person.
- The only previously implemented signals of Luxembourg were the
catenary ones. I have replaced these to better match their actual design
(as opposed to the French one).
- This probably doesn't matter to anyone but me, but the SVGs are
(except for letters and numbers) entirely written in a text editor which
makes the source code compact and me happy. :)

Due to the large number of signals, I will just show some screenshots
for demonstration. Please ask if you have any questions regarding
specific signals. Most of them can be seen around Luxembourg,
Bettembourg, Ettelbruck and Dudelange-Ville station.

Ideally this can be solved more properly when
maplibre/maplibre-gl-js#2108 is implemented,
to render bridges and tunnels for multiple levels over each other in the
correct order.

Closes #549 

### Railway line states

Railway lines under construction and proposed are shown from zooms 7
onwards. These are a single dashed line with the train protection under
construction if defined, and otherwise the train protection.

Present railway lines show one, two or three train protection systems
present on the line, with dashes in multiple colors. If additionally a
train protection system is under construction, it will be shown with
dashes "around" the solid line.

### No train protection

Previously there were explicit combinations configured for the case when
one or more train protection tags were set to `no`. Instead, if no train
protection system is matched, a check is done against all known tags. If
any of the tags is `no`, and all tags which are not `no` are missing,
the railway line is classified explicitly has having no train
protection.

Currently the individual voltages and frequencies are shown.

When two voltages and two frequencies are tagged, the conversion is
determined instead, formatted.

At this moment the `frequency_conversion` is not used at this point. See

At the moment the colors of railway lines under construction or are
proposed are not rendered correctly and become gray.

The composed Maplibre expressions were not handled correctly in the

Fixes #967 

If the user has enabled location tracking, the UI will request the
browser to disable sleep.

See https://developer.chrome.com/docs/capabilities/web-apis/wake-lock
See
https://stackoverflow.com/questions/6106747/can-i-prevent-phone-from-sleep-on-a-webpage
See https://w3c.github.io/screen-wake-lock/
See
https://maplibre.org/maplibre-gl-js/docs/API/classes/GeolocateControl/


Semantics:
- By default does not do anything
- When the user requests location tracking, the browser wake lock is
enabled
- When the user stops location tracking, the browser wake lock is
disabled
- When the user is using location tracking, but moves the map, the wake
lock is disabled until the user re-enables full location tracking
This PR should fix the recent failures in nightly updates.

Recent update to what details are shown for traction substations
improperly uses `%d` in `string.format`.\
`%d` accepts only integers, for real numbers `%f` should be used
instead. That's fixed in this PR.

Do note, that this PR changes the intended behaviour see changes in
tests.

In GB, shunt and distant signals are displayed below main signals.
(See:

[https://en.wikipedia.org/wiki/UK_railway_signalling#Position_light_signals](https://en.wikipedia.org/wiki/UK_railway_signalling#Position_light_signals)
and

[https://en.wikipedia.org/wiki/UK_railway_signalling#Semaphore_signals](https://en.wikipedia.org/wiki/UK_railway_signalling#Semaphore_signals))

I've moved the shunt and distant signals before main signals in
signals_railway_signals.yaml so that they are displayed below the main
signal.

**PR number 1000 🎉**

Fixes #979

Enabled by maplibre/maplibre-gl-js#1235 and
maplibre/maplibre-gl-js#5812. Supported since
Maplibre GL JS version 5.8.0.

See https://maplibre.org/maplibre-style-spec/layers/#line-dasharray

We can combine duplicated map layers that use different dashes. The
`line-dasharray` supports a data-driven style.

We still have to duplicate dashed lines and non-dashed lines, because
`line-cap` is not data-driven. For lines with a dasharray, the line cap
should be `butt` while for non-dashed lines the line cap should be
`round`.

Deduplicating railway lines with dashes will cause the map style to
contain less layers, causing the map to load quicker. Less layers will
also cause the map to show tiles quicker, because less layers have to be
evaluated for each feature on the map.

Layer differences:
- infrastructure: from 586 to 464
- speed: from 78 to 58
- train protection: from 144 to 166 (because of a correctness split of
dual/multi train protection system lines with/without dashes)
- electrification: from 134 to 74
- track: from 117 to 82
- operator: from 80 to 60
- routes: from 72 to 52

Having edited a lot of railways in Serbia I realized that they mostly
have `operator=Железнице Србије` that is wrong since 2015 when the
company was split according to the EU Fourth Railway Package. The
company managing the infrastructure is called [Инфраструктура Железнице
Србије](https://en.wikipedia.org/wiki/Serbian_Railways_Infrastructure).
I'm reluctant to batch rename until this is rendered properly here.

Apart from that Željeznice Republike Srpske operate in Republika Srpska
that is a constituent entity of Bosnia and Herzegovina, not Serbia, so I
moved the railway operator accordingly. Also fix a small mistake in some
Russian operator name.
