Template:S-line/doc

S-line is a specialised succession box template that links railway station articles.

Note: this template is called by {{s-rail-national}}; an alias. If a change is made which alters/adds parameters names that template must be updated to reflect the new situation.

Usage

S-line must be encased within {{s-rail-start}} and {{s-end}}. The use of {{s-rail}} is highly recommended but not required.

S-line has the following parameters:

Parameter	Description	Notes
system	The system to which the line belongs	This should correspond to an entry in Template:S-rail/lines
line	The name of the line	This should be obvious shorthand (e.g. Orange for Orange Line)
previous	The name of the previous station
next	The name of the next station
type	The left-hand line branch	Optional
type2	The right-hand line branch	Optional
note	Information about the left-hand line branch	Optional
note2	Information about the right-hand line branch	Optional
notemid	Information about the station itself	Optional
oneway1	Indicates that trains do not operate towards the Previous station	Optional
oneway2	Indicates that trains do not operate towards the Next station	Optional
rows1, hide1	Used to have the Previous Station box cover multiple lines. See below for details.	Optional
rows2, hide2	Used to have the Next Station box cover multiple lines. See below for details.	Optional
rowsmid, hidemid	Used to have the middle (Line) box cover multiple lines. See below for details.	Optional
transfer	Used to show lines available by direct transfer at an adjoining station. See below for details.	Optional
branch	Used to denote specific line branch information, in lieu of or in addition to the type parameters.	Optional
state1, state2	Allows the passing of an additional station parameter. Useful for disambiguation.	Optional
through1, through2	Allows, instead of a next station, service passing to another line on the system.	Optional

Making it work

S-line depends on sub-templates for the proper display of information. For an example, here are the templates necessary to properly display this box (a version of which is at Vauxhall station):

Preceding station		London Underground		Following station
Template:LUL stations towards Template:LUL stations		Victoria line		Template:LUL stations towards Template:LUL stations

First of all, here's the underlying code:

{{s-rail-start}}
{{s-rail|title=LUL}}
{{s-line|system=LUL|line=Victoria|previous=Stockwell|next=Pimlico}}
{{s-end}}

Template:S-rail-start is a variant of the generic template {{s-start}} used to begin thousands of succession boxes. Important note: No form of start template ({{s-rail-start}} or {{s-start}}) is needed when the succession box is inside the service parameter of {{Infobox station}}. Template:S-rail is used to generate headings for each grouping of rail services in a box. Here we have only one, but some particularly large terminals may have three or four (see Union Station (Chicago) or 30th Street Station). S-rail uses the translation table at Template:S-rail/lines; if the entry is undefined, it simply links the text. Therefore, Amtrak produces Amtrak, while LUL gives London Underground.

You can see that S-line takes only parameters – no linking necessary! S-line accomplishes this through two assumptions: (1) groups of articles on train stations are named in a predictable manner; (2) redirects are cheap. For S-line to produce the table above five separate templates were defined. Before discussing them, however, let's review the parameters:

• SYSTEM: The company or grouping to which the line belongs. This is case-sensitive and must be consistent. In this case, the value is LUL.
• LINE: The line name. This is also case-sensitive and must be consistent throughout. Here, we're describing the Victoria Line.
• PREVIOUS and NEXT: The names of the previous and next stations on the line. Current convention suggests West/East Left/Right, followed by North/South, but your mileage may vary. Whenever possible, succession boxes should make geographic sense (i.e. don't have one line running west-east and the other east-west).

You need templates to define the following things: the formatting/linking of the line, the formatting/linking of the previous and next stations, the display of the line's color, and the display of the appropriate termini – all automatic.

Line

[[Template:{{{SYSTEM}}} lines]] (Template:LUL lines)

This template carries a translation table for the formatting/linking of the line. The template receives one parameter, {{{1}}} from S-line. With systems that have unusual or non-uniform naming, like Amtrak, it may be necessary to have a test case for every line. When a system has uniform naming, you may be able to get away with a default case and only one or two exceptions, as in Template:LUL lines:

{{#switch:{{{1}}}
 | #default=[[{{{1}}} Line]]
}}

Station

[[Template:{{{SYSTEM}}} stations]] (Template:LUL stations)

This template carries a translation table for the formatting/linking of the line. The template receives two parameters from S-line, {{{station}}} and {{{line}}}, although use of the latter is not often necessary. Station will be either the PREVIOUS or NEXT parameter; both are handled the same way behind the scenes. The easiest way to start the station template is with the default case that reflects how articles on system stations are named. With the London Underground, it's done this way:

 | [[{{{station}}} tube station|{{{station}}}]]

Therefore, "Bayswater" produces [[Bayswater tube station|Bayswater]], all linked and ready to go.

Color

[[Template:{{{SYSTEM}}} color]] (Template:LUL color)

This template is designed the same way as the others except that a default case is rare--lines within a system tend to have a different color. Note that some systems don't have a switch statement, because only one color is used. Such a template would consists only of a hex code. The pound sign is included within s-line so it isn't necessary to add it. This template forces the use of hex codes; no nouns are permitted (e.g. red, white). The template takes one parameter, {{{1}}}.

{{#switch:{{lc:{{{1}}}}}
 | bakerloo | bak = a45a2a
 | central | cen = da291c
 | circle | cir = ffcd00
 | chelsea-hackney | c-h = 8cc63e
 | crossrail | cr = {{LCR  color}}
 | crossrail2 | cr2 = e1eb5b
 | district | dis = 007a33
 | east london | ell = ffa300
 | fleet = 414b56
 | hammersmith & city | h&c = e89cae

   | #default = {{tramlink color}}
  }}
 | tl1 = {{tramlink color|1}}
 | tl2 = {{tramlink color|2}}
 | tl3 = {{tramlink color|3}}
 | tl4 = {{tramlink color|4}}
 | thameslink = 5c2483
}}

Termini

[[:Template:S-line/{{{SYSTEM}}} left/{{{LINE}}}]] (Template:S-line/LUL left/Victoria)

[[:Template:S-line/{{{SYSTEM}}} right/{{{LINE}}}]] (Template:S-line/LUL right/Victoria)

These are the all-important templates which produce the "towards..." part of the templates. They can also get pretty tricky depending on the setup. The Victoria line is an easy example. It runs end-to-end from Brixton to Walthamstow Central. Therefore, the "left" (southbound) template contains "Brixton" while the "right" (northbound) template contains "Walthamstow Central". These names are plugged in to the STATION template just as NEXT and PREVIOUS were, with the results that you can see above. A feature of S-line is that if it detects that the next station is the name as the terminus, it will display a note to that effect instead of the destination. Hence,

{{s-start}}
{{s-rail|title=LUL}}
{{s-line|system=LUL|line=Victoria|previous=Brixton|next=Vauxhall}}
{{s-end}}

Produces the box:

Now, let's say we've got a more complicated example, like the London Underground's Northern line, which runs from Morden north to one of three destinations: Edgware, Mill Hill East, or High Barnet. The Northern line's "left" template is still a simple line of text – Morden – but the "right" template needs a switch statement. The left and right templates receive one parameter, {{{type}}}, from s-line, which tells them which termini to return. Here's a simplified version of the Northern line's "right" template: {{#switch:{{{type}}} | Edgware=Edgware | High Barnet=High Barnet | Mill Hill East=Mill Hill East | Three=Edgware, Mill Hill East or High Barnet | Two=Mill Hill East or High Barnet | Kennington=Kennington }} This allows any combination of northbound destinations; depending on which branch the station is on. A default statement is acceptable here if it is true for disproportionate length of the line. In order to make this work properly, you have to define the concepts of "Edgware, Mill Hill East or High Barnet" and "Mill Hill East or High Barnet" in the STATION template, like so:

 | Mill Hill East or High Barnet=[[Mill Hill East tube station|Mill Hill East]] or [[High Barnet tube station|High Barnet]]

Here's a hypothetical example of this at work:

{{s-start}}
{{s-rail|title=LUL}}
{{s-line|system=LUL|line=Northern|previous=Clapham North|next=Oval|type=Morden|type2=Three}}
{{s-end}}

Produces the box:

One-way operation

For rail lines that operate in only one direction (such as going around a loop), the oneway1 or oneway2 parameters are used, to indicate that the Previous or Next station, respectively, does not have service going towards it. When these parameters are present with any non-null value, the toward [Terminal] line is replaced with One-way operation. For example, at Heathrow Terminal 4 tube station:

{{s-start}}
{{s-rail|title=LUL}}
{{s-line|system=LUL|line=Piccadilly|next=Heathrow Terminals 2 & 3|branch=Heathrow|rowsmid=2|type=Heathrow 4|rows1=2|notemid=(Terminal 4 loop)}}
{{s-line|system=LUL|line=Piccadilly|type=Heathrow 4|next=Hatton Cross|oneway2=true|hide1=yes|hidemid=yes}}
{{s-end}}

Produces the box:

Circular operation

Parameters circular (both sides), circular1 (left cell only) and circular2 (right cell only) are useful for lines that operate in uninterrupted circular manner. These parameters simply hide the word "toward(s)" and then you need to edit the succession templates of that circular line to describe the direction and position of either side. The following example uses circular1 and circular2 with the terms "Clockwise" and "Counterclockwise":

Alternatively, the following example uses circular, and the north american english term "counterclockwise" is interchanged with the commonwealth english term "anticlockwise".

{{s-rail-start}}
{{s-rail|title=MOSMETRO}}
{{s-line|system=MOSMETRO|line=Koltsevaya|previous=Krasnopresnenskaya|next=Novoslobodskaya|circular=yes}}
{{s-end}}

Produces the box:

Preceding station		Moscow Metro		Following station
Template:MOSMETRO stations Template:MOSMETRO stations		Koltsevaya line		Template:MOSMETRO stations Template:MOSMETRO stations

Through operation

When there are different rail services connected on the same line, the through1 or through2 parameters are used to differentiate said services. When these parameters are present with any non-null value, the toward [Terminal] line is replaced with through to [Adjacent line]. This incorporates the use of previous and next, with the use of an adjacent line instead of an adjacent station. These parameters are not commonly used, but an example from Jamaica station:

{{s-rail-start}}
{{s-rail|title=LIRR}}
{{s-line|system=LIRR|line=City|previous=Kew Gardens|next=Branches|type=Penn Station|through2=yes}}
{{s-line|system=LIRR|line=Belmont Park|next=Belmont Park|previous=City|through1=yes|notemid=special event service}}
{{s-end}}

Produces the box: Template:Adjacent stations

Parallel lines

For lines that operate on the same tracks and serve the same next station and final terminal, the rows1, rows2, hide1, and hide2 optional parameters can be used to have the Previous (the 1s) or Next (the 2s) Station boxes cover more than one line. The rows parameters specify how many lines the station should cover, while the hide parameters ensure that the table formatting remains intact. The two parameters must be used together, with hide specified for every line that is being covered by the first line. An example of this use can be seen in the preceding CTA box. Note that, in the preceding CTA example, the previous and oneway1 parameters could have been omitted from the Purple and Pink line entries, but were left in for consistency's sake.

Another example of this:

{{S-start}}
{{S-rail|title=LUL}}
{{S-line|system=LUL|line=Circle|previous=Westbourne Park|next=Paddington|type2=Aldgate|rows1=2}}
{{S-line|system=LUL|line=Hammersmith & City|previous=Westbourne Park|next=Paddington|hide1=yes}}
{{S-end}}

Produces the box:

Transfers

The transfer parameter makes it possible to show within the box lines available at a different station with which there's a direct transfer from the current station. This snippet is taken from the article about the Finchley Road tube station. The North London Line does not actually serve the station itself, but there's an official out of system transfer designated between London Underground services at Finchley Road and London Overground services at the nearby Finchley Road & Frognal station:

{{s-start}}
{{s-rail|title=LUL}}
{{s-line|system=LUL|line=Jubilee|previous=West Hampstead|next=Swiss Cottage|type2=one}}
{{s-line|system=LUL|line=Metropolitan|previous=Wembley Park|next=Baker Street|type=Four|rowsmid=2|rows2=2}}
{{s-line|system=LUL|line=Metropolitan|previous=Harrow-on-the-Hill|next=Finchley Road|type=Four|hidemid=yes|hide2=yes|note=Peak periods only}}
{{s-note|text=Out-of-system interchange}}
{{s-rail|title=LOG}}
{{s-line|system=LOG|line=North London|previous=West Hampstead|next=Hampstead Heath|transfer=Finchley Road & Frognal}}
{{s-end}}

Produces the box:

Branches

The branch parameter can be used to describe a subset of a line. In the example hereafter, the branch parameter designates four different parts of the MBTA's Green Line. When passed to the left and right termini templates, the branch and line parameters identify destinations. Additionally, the branch name is displayed beneath the line name.

Optionally, [[Template:{{{SYSTEM}}} lines/branches]] may be defined, which allows the linking of the branch parameter.

In this example hereafter, taken from the Acton Town tube station article, the branch template (Template:LUL lines/branches) is defined, allowing branch linking. Additionally, through the branch parameter, the left and right hand termini are generated. In some cases, a type parameter can be used to supplement the branch parameter. If necessary, a notemid= parameter can be used to substitute for a branch parameter.

{{s-start}}
{{s-rail|title=LUL}}
{{s-line|system=LUL|line=District|previous=Ealing Common|next=Chiswick Park|type=Ealing Broadway|type2=One}}
{{s-line|system=LUL|line=Piccadilly|type=Uxbridge|notemid=[[Piccadilly line#Uxbridge branch|Uxbridge branch]]|previous=Ealing Common|next=Turnham Green|note2=Early morning and late evening service only|rowsmid=2|rows1=2}}
{{s-line|system=LUL|line=Piccadilly|branch=Uxbridge|previous=Ealing Common|next=Hammersmith|hidemid=yes|hide1=yes}}
{{s-line|system=LUL|line=Piccadilly|branch=Heathrow|previous=South Ealing|next=Turnham Green|note2=Early morning and late evening service only|rowsmid=2|rows1=2}}
{{s-line|system=LUL|line=Piccadilly|branch=Heathrow|previous=South Ealing|next=Hammersmith|hidemid=yes|hide1=yes}}
{{s-end}}
