Openttd Junctions. For a list of engines and carriages see the trains category. This is a list to clarify the usefulness of a junction.
Junctions are formed at any point where a piece of railway track directly crosses or joins another piece. In openttd references to junctions are almost always talking about rail junction because the other modes of transport either do not need them or they are trivial to build. Building stations efficiently is very important if you wish to establish a great train empire.
