| Speed limits are modelled in {{rml}} using {{tag|is|speedSection}} elements in combination with {{tag|co|speedProfile}} elements. A simple example is shown [[#examples|below]]. A more complex example is provided in [[CO:speedProfile#Example3|Example 3 of {{rml}} element <speedProfile>]].

| A speed limit valid for a speed section is presented in {{rml}} by a {{tag|is|speedSection}} element. The {{tag|is|speedSection}} element defines the start and end location of the speed section and the maximum speed limit valid for this section.

| ;The modelling in {{rml}} is:
| |
| <syntaxhighlight lang=xml>
| |
| <speedSection id="spsec100" maxSpeed="80" isTemporary="false" isSignalized="false">
| |
| <name name="JNA-201" description="Speed section" language="EN"/>
| |
| <linearLocation id="spsec100_lloc" applicationDirection="normal">
| |
| <associatedNetElement netElementRef="ne_102" keepsOrientation="true"
| |
| posBegin="200.0" posEnd="600.0">
| |
| <linearCoordinateBegin positioningSystemRef="lps01" measure="11200.0"/>
| |
| <linearCoordinateEnd positioningSystemRef="lps01" measure="11600.0"/>
| |
| </associatedNetElement>
| |
| </linearLocation>
| |
| <validForSpeedProfile ref="ssp_basic"/>
| |
| </speedSection>
| |
| </syntaxhighlight>
| |
| Each {{rml}} {{tag|is|speedSection}} element must reference (at least) one global defined {{rml}} {{tag|co|speedProfile}} element. A {{tag|co|speedProfile}} element specifies a train type for which the speed limit given by a {{tag|is|speedSection}} element shall be valid.
| |
| | |
| For example a {{tag|co|speedProfile}} element can be used to provide for ETCS a '''''Basic''' Static Speed Profile'', a '''''Specific''' Static Speed Profile'' (cant deficiency or brake type depending train categories, ETCS Operational Train categories or International Train Categories) or an '''''Axle Load''' Speed Profile''.
