This template employs intricate features of template syntax.
You are encouraged to familiarise yourself with its setup and parser functions before editing the template. If your edit causes unexpected problems, please undo it quickly, as this template may appear on a large number of pages.
You can conduct experiments, and should test all major changes, in either this template's sandbox, the general template sandbox, or your user space before changing anything here.
The markup for composing the diagram in the |map= parameter is different to the {{BSrow}}-based templates. The major differences are the separators in each row. Subtemplates are not necessary, since a new row in the table is simply created by a carriage return (newline).
{{Routemap
Add other parameters like |title= here.|map=
Map markup goes here!}}
The third and fourth pairs of tildes can be omitted if there is no content following either of them.
After the last icon ID, if there is only one set of "tilde-tilde" (~~), the following text will be displayed in the main text cell instead of dist./time.
Separating text cells requires at least one empty space; otherwise the tildes will be treated as a signature.
Aside from bg=, there are several other parameters, separated by commas (,), which can be used to customize the display of a row. Only bg= can be used to change the display of icons; all others only affect text cells.
Parameters for all of a stack of multiple overlaid icons and/or text boxes (or a single icon or text box with no overlays) are separated to the left by an exclamation mark and an underscore (!_). This must go after the link (if any).
Parameters for part of a stack of multiple overlaid items are separated to the left by two underscores (__).
For the last overlaid item in a stack, the individual item parameters (if any) must go before the stack parameters.
Most of the parameters are the same as those for rows, but there are a few additional ones. Additionally, the values for align=, bg= and color= can override those of the row parameters.
For larger and more complicated diagrams, it often helps to have a text sidebar on the left as well as the right.

Left text cells require "exclamation mark-space-exclamation mark" (!!) separating them from icon cells.
If there is no "tilde-tilde" (~~) separator to the left of "exclamation mark-space-exclamation mark", the text to the left of the separator will be displayed in the left main text cell.
Many contributors of the English Route Diagram Template project during the implementation of Routemap have conflicting opinions about the justification of replacing all maps of legacy BS row templates by the Lua-based Routemap. Opponents deem the map markups of Routemap to be too esoteric for editors unfamiliar with Routemap markup to modify. While proponents support a complete conversion for better performance. There is no consensus reached at the moment so any transition without massively updating the map appearance for reflecting service and/or structural change in reality should only be done with the following considerations:
The map of the legacy BS row template design has exceeded template size limit in the transcluding page, which means the template does not expand into its intended appearance but only the link to the template page is shown, so there is an imminent need to translate the map into Routemap design to reduce post-expand include size.
If there is no template size issue, respect the preference of the initial contributor of the first completed version of the diagram. If that contributor contests the change to Routemap, retain the BS row template design.
All BS row templates have been amended with safesubst commands, hence conversion can be easily done by adding the safesubst: markup before every BS row template name in the map. For example, change {{BS2|STR|BHF|0|1|2|3|O1=uSTRq}} in the map to {{safesubst:BS2|STR|BHF|0|1|2|3|O1=uSTRq}}, then save change, it will produce STR!~uSTRq\BHF~~0~~1~~2~~3. The process can be sped up by using the "replace all" function of advanced edit tool or separate text editor such as Notepad or Notepad++, but the search rule for the BS row templates should be specified to the number of icon columns in order to avoid templates with similar name such as BSto and BSsplit in case they are present in the map.
"Column mode editing" can avoid the trouble of find and replace to add safesubst: on all rows efficiently. This function is common in advanced text editors like Notepad++ and Sublime Text.
You can also use the "convertbs" function of Modeule:Routemap or an Unix script.
Copy/paste the following code to any edit area of this wiki, maybe the map page you are working on:
{{#invoke:Routemap|convertbs|<nowiki>
</nowiki>}}
Then copy/paste the original BS-map or Railway line header map code between the <nowiki> tags (alternatively paste the invoke convertbs header before the original map code and the </nowiki>}} ending after the map code) and show preview. It will generate the safesubst version and show the original versions (for comparison) of the map code. You copy the safesubst code from the preview area back to the edit area, and you should remove everything of #invoke:Routemap|convertbs if the preview of the new code works properly.
Example
{{#invoke:Routemap|convertbs|<nowiki>
{{BS-map
|title=Demonstration
|map=
{{BS|KBHFa|0 km|A station|Shuttle bus}}
{{BS3|WASSERq|hKRZWae|WASSERq||||{{BSsplit|Suburb|Capital}}}}
