View source for BSicon/Catalogue

This catalogue is maintained manually and therefore ''may not include all available icons''. Refer to the following for complete catalogues by category:
* [[:Category:BSicon/railway|Railway icons]]
* [[:Category:BSicon/road|Road icons]]
* [[:Category:Icons for canal descriptions|Canal icons]]

The original list was split into smaller sub-lists due to it taking too long to load all the icons. Editors may create new sub-lists if the existing sub-lists become too long or are unsuitable for including the desired icon. See the [http://en.wikipedia.org/w/index.php?title=Wikipedia:Route_diagram_template/Catalog_of_pictograms&oldid=244943628 Catalog of pictograms] for the pre-split list.

The basic diagrams are primarily used to show
:{|

Note that the number of lines (tracks) is not normally shown in diagrams, except in depictions of small areas such as stations and individual light rail/tram lines.

== Introduction ==

BSicons are generally named logically, and different icon names can often be modified in the same way. Some examples:

== Naming logic ==
This system of icon names was originally created on the German Wikipedia in 2006, and has since been expanded by editors on different projects. Consequently, most icon names are derived from German, and the rest from English and Dutch.

BSicon files are named <code>File:BSicon <var>pictogram-ID</var>.svg</code>. (The ID of an icon is entered (without "BSicon") into {{tl|Routemap}} or into the {{tl|BS-map}} helper templates. Usage instructions for those templates are at [[Template:Routemap]] and [[:w:en:WP:RDT]] respectively.) The ID is constructed from a '''root''', usually with prefixes and suffixes (e.g. {{bsq|tKBHFa}} refers to a pictogram derived from <code>{{abbr|t|tunnel}}+{{abbr|K|terminus}}+'''{{abbr|BHF|station}}'''+{{abbr|a|start}}</code>). Prefixes and suffixes are mostly lowercase, but the root is all caps (capital letters), with only a few exceptions. All icons contain at least one root,{{efn|Except the blank icons used as spacers.}} and sometimes two or more are combined to form complex icons. Affixes generally modify the "base" icon in color, directionality, structure, etc., and may not be necessary for simple icons.

==== Prefix ====
The prefixes generally indicate the status of the infrastructure.
: Zero or more of these prefixes:

===== Parallel lines =====
All icons with a symmetrical subject such as bridges (either highway, normal or waterway), borders and tunnels but ''excluding'' icons for crossings with other railway lines and stations use the following naming convention:
* '''v''' prefix, both lines in use: {{bsq|vSKRZ-Au|0}}, {{bsq|vBRÜCKE1|0}}, {{bsq|vWTUNNEL|0}}
* '''ev''' prefix, left line disused, right line in use: {{bsq|evSKRZ-Au|0}}, {{bsq|evBRÜCKE1|0}}, {{bsq|evWTUNNEL|0}}
* '''xv''' prefix, left line in use, right line disused: {{bsq|xvSKRZ-Au|0}}, {{bsq|xvBRÜCKE1|0}}, {{bsq|xvWTUNNEL|0}}
* '''exv''' prefix, both lines disused: {{bsq|exvSKRZ-Au|0}}, {{bsq|exvBRÜCKE1|0}}, {{bsq|exvWTUNNEL|0}}

For crossings the prefix applies to the crossing line:
* '''v''': {{bsq|vKRZu|0}}
* '''ev''': {{bsq|evKRZu|0}}
* '''xv''': {{bsq|xvKRZu|0}}
* '''exv''': {{bsq|exvKRZu|0}}

For symmetrical stations the pattern is the same as for crossings, where the prefix is placed before the '''v''' and denotes the entire station:
* '''v''': {{bsq|vBHF|0}}
* '''ev''': {{bsq|evBHF|0}}
* '''exv''': {{bsq|exvBHF|0}}

For asymmetrical stations, prefixes which only apply to one half are placed after the '''v''':
* {{BS-q|vSTR-BHF}}
* {{BS-q|vexSTR-BHF}}
* {{BS-q|vSTR-eBHF}}
* {{BS-q|vSTR-exBHF}}

====== Transverse parallel lines ======
This subgroup covers icons where the parallel lines run across. If the icon name does not need a separating dash, then the name is the same as the regular icon, with the addition of the suffix '''q''' (for '''q'''uarter turn):
{|
| {{BS-q|vSTR}} || {{BS-q|vSTRq}}
|-
| {{BS-q|evCONTf}} || {{BS-q|evCONTfq}}
|-
| {{BS-q|uvBHF}} || {{BS-q|uvBHFq}}
|}

Other icons are named as if they were two regular icons, one above the other. Prefixes that only apply to the first half of the icon are separated from any preceding prefixes by the '''^''' (caret) character where necessary; in all other cases, no prefix is used to indicate transverse parallel lines.

{|
|-
| {{BS-q|uSTRq-STR+r}} || {{BS-q|uSTRq}}<br>{{BS-q|uSTR+r}} || '''u''' prefix applies to both halves
|-
| {{BS-q|KRZu-mKRZu}} || {{BS-q|KRZu}}<br>{{BS-q|mKRZu}} || '''m''' prefix applies to bottom half
|-
| {{BS-q|^mKRZo-KRZo}} || {{BS-q|mKRZo}}<br>{{BS-q|KRZo}} || '''m''' prefix applies to top half only
|-
| {{BS-q|^emKRZu-KRZu}} || {{BS-q|emKRZu}}<br>{{BS-q|KRZu}} || '''em''' prefix applies to top half only
|}

The following concerns parallel lines produced from single icons, and how those icons (if they exist) would be named. There are also applications of route diagrams where "parallel lines" are depicted using several columns of single line icons. If a diagram feature you have seen on some other Wikipedia page may be expressed in terms of the prefixes above, but you fail to reproduce it that way, then this may be because that other page used several columns.

===== Other geometry =====
If {{bsn|q}} (quarter turn) is part of [[#Suffix|the title suffix]], the primary line line runs across the page, from left to right.

Some suffix title codes, for instance {{bsn|u}}, {{bsn|o}}, imply grade separation, also {{bsn|t}}, {{bsn|h}} if used once.  This determines which line is drawn over ({{math|z}}-layer above) the other. If both lines are on same level, then the secondary track is usually shown below the primary (z-layer under), unless the primary is out of use and the secondary is in use.

There are a few "pseudo"-roots that do not follow the all-caps rule, such as {{bsn|num}} (e.g. {{bsq|num1r}}) and {{bsn|Lock}}.

=== Connectors ===
Some icons have more than one feature, in which case connectors are used to join multiple roots.

{|class=wikitable
! colspan="2" |  !! Relationship !! Example !! Description
|-
! rowspan="4" scope="row" | {{pad}} {{float|left=-2em|top=-1.5em|{{Rotate text|270|Connector}}}}
! scope="row" | <kbd>-</kbd>
| parallel || {{bsq|vSTR-DST}}<br />{{bsq|STRq-STR+l}}
| Used between adjacent objects in parallel lines syntax. Prefixes and suffixes can be applied to each root independently, but are applied to both objects if used at the beginning of the icon name. The absence of the {{bsn|v}} prefix indicates that the parallel lines are transverse.
|-
! scope="row"| <kbd>+</kbd>
| stacked || {{bsq|STR+GRZq}}
| Used to place multiple objects in the same icon without affecting their positions. All prefixes, suffixes and colours are applied to each root independently. Where applicable, the second object (from left to right) is layered above the first one, and so on.
|-
! scope="row"| <kbd>;</kbd>
| modified || {{bsq|v-2SHI2+r;g2}}
| Used to combine objects with different geometries. {{bsn|;ABZg}} is abbreviated as {{bsn|;g}} and {{bsn|;KRZ}} is abbreviated as {{bsn|;}}. In the latter case, {{bsn|KRZ}} prefix and suffix logic is used for all of the objects.
|}

=== Suffix ===
Suffixes in this category indicate the directionality, position or structural variation. Note that directions are based on as if travelling along within a standard, '''top-to-bottom route'''.

Four common suffixes are left, right, forward and backward:
* '''l''' [''links'', German for "left"],
* '''r''' [''rechts'', German for "right"],
* <span style="color:#888">'''f''' [''Fahrtrichtung'', German for "direction of travel"] (forward, basically) and</span>
* <span style="color:#888">'''g''' [''Gegenrichtung'', German for "opposite direction" (of travel)].</span><br/>&nbsp;

After the first BSicons were created in 2006, it was soon realized that the system with '''f''' and '''g''' was very limited, especially when dealing with icons facing across. Therefore, the '''+''' suffix—in the sense of "coming from"—was introduced.

'''l''' and '''r''' have been used mistakenly as left and right as the reader sees it; there is no "u" for "up [the page]" and "d" for "down [the page]", hence instead the icons are designed as if moving inside a classical 'down' track route that is being depicted instead.

In 2018, additional variations of the '''l''', '''r''', '''f''' and '''g''' suffixes were introduced in order to reduce naming conflicts and increase specificity; these additions are shown in the table in the {{section link||Suffix modifiers}} section.

{{anchor|gq_pair}}<span style="color:#888">''Caveat:'' Depending on context '''g''' also pairs with '''q''', them sharing letter positions wrt other suffix codes. In this respect ''g'' usually stands for [''geradeaus'', German for "straight" or "straight ahead" – analogous to "throu'''g'''h" in English].{{efn|introduced in 2013, possibly before: [[Talk:BSicon/Renaming/ABZ#Former_ABZ3]]}}{{efn|Symbol '''g''' polymorphism in BSicon titles can be confusing, esp. because the letter in root's prefix has yet another meaning. Comparing titles of a set can aid in getting an interpretation that fits, but this is unstable at times when title mapping is disputed, discussed and/or adjusted to accomodate for new/ambiguously named icons.}} The letter tuple is then employed to bisect straight (top-bottom) from across track (left-right) attributed icon variants in applicable icon sets.</span>

Some suffixes have the same meaning across all icons, but others may have root-specific meanings. For example, the '''l''' and '''r''' suffixes on their own typically produce a 90° turn, but this is not the case for the BS, BS2, FOW, KRW, PSL, SHI, TEE, ÜST, ÜWB or WSL roots, and is only sometimes the case for KRZ.

Other codes are made from joining these together. Additional icons can be created by overlaying existing ones.

==== Suffix modifiers ====

* A '''primary object''', as used here, is usually the line.
* A '''secondary object''' is usually an object on the line, or one which would be on a line, like a station. The crossing line of {{bsq|KRZo}} is also defined as the secondary object.
* An '''auxiliary object''' is an object which is not a line (or roadway) and which does not change colour with the {{bsn|ex}} prefixes, such as a formation: {{bsq|lBRÜCKE|0}}.

== Colours ==
* '''dark''' colour means a currently open line / facility
* '''light''' colour means ''either'' a closed line / route / facility ''or'' one under construction / planned
* '''red''' indicates heavy rail or freight line
* '''blue''' indicates light rail, metro or tram line; or canal
* '''green''' indicates specific uses: nominally footpaths and unwatered canals, but also [[:en:track gauge|other gauges]] or special circumstances such as [[:en:free public transport|fare-free]] zones.

=== Colour sets ===
There are [[:Category:BSicon/railway/other colors|34]]{{efn|As of January 2019. The ruby and teal sets have also been extended into exruby and exteal respectively.}} BSicon sets in addition to the four standard sets:
{|

|}

Many standard icons, including some of those needed for drawing more complex track geometries, are available in all 37 sets. The smallest set, carrot, contains 1,662 icons.{{efn|1=As of January 2019 (PetScan: [https://petscan.wmflabs.org/?language=commons&project=wikimedia&depth=25&categories=BSicon&show_redirects=no&sortby=title&add_image=on&regexp_filter=File%3ABSicon%20.*carrot.*\.svg&interface_language=en&active_tab=&doit= HTML], [https://petscan.wmflabs.org/?language=commons&project=wikimedia&depth=25&categories=BSicon&show_redirects=no&sortby=title&add_image=on&regexp_filter=File%3ABSicon%20.*carrot.*\.svg&interface_language=en&format=csv&active_tab=&doit= CSV]).}} However, most tables in this catalogue only show the heavy rail and metro sets. For an overview of the icons in other sets, see [[User:YLSS/BSicon/navbox|the catalogue by YLSS]].

New colours can be proposed at [[Talk:BSicon/Colors]].

=== Naming ===
Icons in the colour sets follow the same naming as regular icons, with the colour name appended.

==== Mixed lines ====
===== Basic colours =====
For icons with both more than one colour, the {{bsn|m}} prefix indicates that the primary line is the default colour and the secondary ({{bsn|u}}, {{bsn|f}} or {{bsn|g}}) is different. A {{bsn|um}}, {{bsn|fm}} or {{bsn|gm}} prefix denotes the opposite.

{|
! m !! um
|-
| {{BS-q|mKRZ}} || {{BS-q|umKRZ}}
|-
| {{BS-q|mABZgl}} || {{BS-q|umABZgl}}
|-
| {{BS-q|xmABZqr}} || {{BS-q|uxmABZqr}}
|}

The '''f''' and '''g''' sets can also be mixed.
{|
|-
| {{bsq|mfKRZ}} || {{bsq|fmKRZ}}
|-
| {{bsq|mfKRZo}} || {{bsq|fmKRZo}}
|-
| {{bsq|mgKRZo}} || {{bsq|gmKRZo}}
|}

If two of the '''u''', '''f''' and '''g''' prefixes are used, '''m''' is omitted.
{|
|-
| {{bsq|fuKRZo}} || {{bsq|ufKRZo}}
|-
| {{bsq|guKRZo}} || {{bsq|ugKRZo}}
|}

When '''m''' is omitted, the '''e''' and '''x''' suffixes are placed between the two sets' prefixes, as in {{bsq|uexfKRZo}}.

===== Named colours =====
[[#Others|Other colour sets]] can also be mixed, but use a different naming scheme: the first colour is the primary line (through line or vertical axis) and the second color is either the branch line or on a secondary axis, separated by a plus symbol (+). A blank adjacent to the {{bsn|+}} indicates that one of the lines is a basic colour.

* {{bsq|mABZgr +yellow}}
* {{bsq|umKRZo +saffron}}
* {{bsq|xmtKRZtu azure+}}
* {{bsq|mvSTR black+orange}}

Some icons may use '''m''' as a suffix instead of a prefix to indicate that a specific element uses the secondary colour. This is usually done by prepending it to another suffix, such as in {{bsq|STRl+mr}}.

== Geometry ==
{{Main|BSicon/Icon geometry and SVG code neatness}}
Standard icons are drawn in a 500 pixel × 500 pixel square. Lines are 100 pixels wide, centred at 250 pixels. Parallel lines are centred on the quarter points, i.e. 125 and 375 pixels, as are formation elements. Thin lines (sidings, feeders, formation elements, linkways, borders, etc.) are 50 pixels wide, and also aligned to the ¼–½–¾ grid.

The documentation for each template explains its usage and syntax.

There are also matching templates that insert the header row for each of the icon row templates. For example, the template &#123;&#123;[[Template:WP:RDT/BSa8/h]]}} creates the first row of this table (which uses &#123;&#123;[[Template:WP:RDT/BSa8]]}}):
{|class=wikitable
