CA AB2262

Requires the State Board of Equalization to determine physical presence of private railroad cars in California based on mileage instead of average number of car days.

Changes the valuation method to include acquisition cost plus additions and betterments (rather than acquisition cost alone), and eliminates the "minus the age at acquisition" depreciation calculation for most car types.

Repeals the definition of "class of private railroad cars" and eliminates the requirement to exclude repair facility data from the California factor calculation.

Requires a 2/3 vote of the Legislature to pass, as authorized by the California Constitution for differential property taxation.
