Can anyone post, or direct me to, performance grading standards, not TCA C10 - C6 cosmetic grades, etc., if they actually exist. Google has not been my friend. And, yes I realize this is not TCA News, but is TCA related.

O-5Full Operability: All operational components of the piece function as described by the manufacturer or as found in available documentation.
O-4Limited Operability: All operational components of the piece function, but there is a limited, intermittent, or sluggish condition noticeable; adjustment, cleaning, lubrication or maintenance is required to bring the piece to FULL OPERABILITY.
O-3Partial Operability: One or more than one operational component of the piece do not function; replacement of parts, either mechanical or electrical, is required in order to restore operability; at least one operational component in the piece must be functioning properly to be described as PARTIAL OPERABILITY.
O-2No Operability: None of the operational components of the piece function properly; might be relegated to “parts only”
O-1
Unknown Operability: The operation of the piece is not known; the current owner either has no way in which to test it or is unfamiliar with proper operational characteristics.

Although I applaud TCA for creating the operational standard, it doesn't seem to have caught on - it's not included in most listings, and it's too easy to default to O-1 (unknown).  Speaking as someone who would never knowingly misrepresent the condition of an item, from the seller's standpoint it's risky to describe something as O-5 (fully operational) - how many of us will test (or use) ALL functions of a DCS or TMCC/Legacy locomotive?  A buyer could legitimately complain if one obscure function doesn't work.
