Rail terminology is a form of technical terminology. The difference between the American term ''railroad'' and the international term ''railway'' (used by the International Union of Railways and English-speaking countries outside the US) is the most obvious difference in rail terminology. There are also others, due to the parallel development of rail transport systems in different parts of the world. Various terms are presented here alphabetically; where a term has multiple names, this is indicated. The note "US" indicates a term peculiar to North America, or "CA" may represent Canada while "UK" refers to terms originating in the British Isles and normally also used in former British colonies outside North America (such as Australia "AU", New Zealand "NZ", etc.). The abbreviation "UIC" refers to standard terms adopted by the International Union of Railways in its official publications and thesaurus. Exceptions are noted; terms whose currency is limited to one particular country, region, or railway are also included. == 0-9 == ; 3-step protection (US) : The protection given by a locomotive engineer to an employee working near, between, or under cars to which the locomotive is coupled, via a three-step process: :# Fully apply independent brake. :# Set reverser to neutral. :# Turn off generator field (or notify the ground employee, depending on company-specific rules and locomotive type, that protection is provided).〔(【引用サイトリンク】url=http://www.csx.com/index.cfm/about-csx/company-overview/railroad-dictionary/?i=T )〕 ; 10 wheeler (US) : A steam locomotive with a 4-6-0 wheel arrangement ; 241 (US) : Procession of a train past a stop signal with verbal permission from the dispatcher.〔(【引用サイトリンク】url=http://www.ihbrr.com/bulletins/7412_NORAC_alt2.pdf )〕 Derives from Rule 241, which is used to grant such permission under certain rule sets. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Glossary of rail transport terms」の詳細全文を読む スポンサード リンク
