Hello! I'm currently working on a dictionary of terms which relate to construction, maintenance and operation of subways. It's both a list of preferred terms for use in our documentation and a Russian-English dictionary. So I'm looking for any dictionaries or any particular guidelines to cross-check my translations and possibly find better English terminology corresponding to Russian one.

Any help with this would be highly appreciated, particularly references to existing dictionaries/lists of terms, especially terminology that comes from different regions. Priority towards signaling system terminology, names of internal components, specific track elements and so on.
