Maintenance

Deprecated parameters

Sorted under "1"

Pages using old parameters of this template will sort to Category:Articles with infobox errors. These deprecated parameters are:

• leadingsize - use |leadingdiameter=
• driversize - use |driverdiameter=
• trailingsize - use |trailingdiameter=
• weight - ambiguous; use one or more of |locoweight=, |tenderweight=, |locotenderweight=

The correct information for the fields should be available on enwp on the articles for the locomotives in question.

Unnamed parameters

Sorted under "2"

The template takes no positional parameters ({{{1}}}, {{{2}}}, etc), so determine if this is a parameter name lacking both equals sign and value, or a parameter value; and then either add the missing half of the parameter, or remove it entirely.

Invalid values

Sorted under "3"

In addition, this category is triggered for certain invalid values being passed in valid parameters.

• image when the relevant image file does not exist

Required fields empty

Sorted under "4"

The complete absence of the name parameter also triggers this category.
