-- This is the data used in [[Module:RailGauge]]. The format is as follows:

--  {
--      ["id"] = "1000",                            -- Gauge identification in mm. Used for checks.
--      ["aliases"] = { [[1000]], [[1000mm]] },     -- Aliases for the gauge.
--      ["name"] = "metre gauge",                   -- The gauge name.
--      ["link"] = "[[metre gauge]]",               -- Link to the Wikipedia article, capitalised as if it were inline text.
--      ["dflt1"] = "met",                          -- The default measurement system, either "met" (metric) or "imp" (imperial).
--      ["m"] = "1",                                -- The metre part of the gauge (for metric measurements).
--      ["mm"] = "1000",                            -- The mm part of the gauge (for metric measurements).
--      ["ft"] = "3",                               -- The feet part of the gauge (for imperial measurements).
--      ["in"] = "3",                               -- The inches part of the gauge (for imperial measurements).
--      ["num"] = "3",                              -- The numerator for fractions of inches (i.e. the "3" in 3/8 inches ).
--      ["den"] = "8"                               -- The denominator for fractions of inches (i.e. the "8" in 3/8 inches ).
--  },

-- The "id", "aliases", and "dflt1" fields are required, and the "name" and "link" fields are optional. There must be at least
-- one metric measurement field and one imperial measurement field. If the "num" is specified, then the "den" field must also
-- be specified, and vice versa.

-- Alias names should not contain any spaces; spaces are trimmed from the input when it is processed, so alias names
-- containing spaces will not be matched. If there are any duplicate aliases, the one appearing earliest in the table will be
-- used. Please try and avoid this.

return {
    -- Highly-used gauges are listed first to speed up table lookup.
