On articles dealing with LNER locomotives, place this near the bottom, above the categories:
{{LNER Locomotives}}
There is one parameter:
state - by default the template is uncollapsed. Use |state=autocollapseor|state=collapsed for variant behaviour. See navbox documentation for further details.
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (anavbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
To change this template's initial visibility, the |state=parameter may be used:
{{LNER Locomotives|state=collapsed}} will show the template collapsed, i.e. hidden apart from its title bar.
{{LNER Locomotives|state=expanded}} will show the template expanded, i.e. fully visible.
