Glossary of terms used in these pages


English-Spanish Spanish-English

Spanish / English

Spanish, like English, is not a single homogeneous language. Different words can be used in different places to express the identical concept. The same word can have very different meanings in different countries in normal usage. For instance, the word hacienda in Argentina (in the context of railways) means livestock; however, its usual meaning in Mexico is something like stately home, in Perú a large crop-producing estate and in Spain (the royal) household. Another is muelle, which in Patagonia means a pier (landing stage; normally of timber piled construction) whereas in Spain it is a spring.

The ultimate authority on language in the Spanish speaking world is the Real Academia who list the variations such as noted above. However, technical terms may not always be recorded by the Real Academia, and may be specific to individual railways, particularly is the railway was of British origin. Where the word is specific, but not necessarily uniquely, to a country or railway, there is an abbreviation indicating the context of the word.
