Provides a standard citation for using the National Electronic Sectional Appendix as a reference, as many rail articles do. No longer a footnote.

{{NESA}}
{{NESA|region=|access-date=|version=}}

When the region parameter is provided, a footnote about that specific data set is generated. All the below examples use {{today}} for the access date and March26 for the version. The region codes are the same as those used by {{NESA}}:
