Bogie

Bogie, a northern English dialect word of unknown origin, applied to a kind of low truck or “trolly.” In railway engineering it is applied to an under-truck, most frequently with four wheels, which is often provided at one end of a locomotive or both ends of a carriage. It is pivoted or swivelled on the main frames, so that it can turn relatively to the body of the vehicle or engine, and thus it enables the wheels readily to follow the curves of the line. It has no connexion with the series of words, such as “bogey” or “bogy,” “bogle,” “boggle,” “bogart” (in Shakespeare “bug,” “bugs and goblins”), which are probably connected with the Welsh bwg, a spectre; hence the verb to “boggle,” properly applied to a horse which shies at supposed spectres, and so meaning to hesitate, bungle.
