Definition of "tidiness"

The amount of external pipework is also unusual in a British locomotive, though apparent in the most recent L.M.S.R. designs, such as the Class "4" 2-6-0s; but while lacking the tidiness of the old school of British locomotive engineering, this has obvious application for maintenance purposes in present circumstances.
