railhead Railhead A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWjXAJwpEbGdrcN5Y29ycA" class="cyc_term">TransportFacility</a>. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r3CW8xkJ_EdqAAAACs0uFOQ" class="cyc_term">Railhead</a> is a terminus of a railway line where materials can be loaded or unloaded from railroad wagons. Typically, a railway will interface with another mode of transport (such as shipping) at a railhead.

These are trains whose <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rv-lujZwpEbGdrcN5Y29ycA" class="cyc_term">primaryFunction</a> is to transport <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViM4pwpEbGdrcN5Y29ycA" class="cyc_term">passengers</a>, not freight.

Train-TransportationDevice <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjIJZwpEbGdrcN5Y29ycA" class="cyc_term">Train_TransportationDevice</a> is a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwHLvC5wpEbGdrcN5Y29ycA" class="cyc_term">WheeledTransportationDevice</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjUQJwpEbGdrcN5Y29ycA" class="cyc_term">TransportationContainerProduct</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwAPux5wpEbGdrcN5Y29ycA" class="cyc_term">PublicTransportationDevice</a>. Each instance of a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjIJZwpEbGdrcN5Y29ycA" class="cyc_term">Train_TransportationDevice</a> is a "train," i.e., a transportation device that runs on <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi-lJwpEbGdrcN5Y29ycA" class="cyc_term">Railway</a>s and consists of multiple <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViTsJwpEbGdrcN5Y29ycA" class="cyc_term">TrainCar</a>s coupled together. train

RailwaySignal railway signal A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjJhJwpEbGdrcN5Y29ycA" class="cyc_term">Signal</a>; each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rFy1yzkJ6EdqAAAACs0x8nw" class="cyc_term">RailwaySignal</a> indicates the beginning of a section of track that may have to be shared with other trains; thus it regulates whether trains can move or stop.

class of concepts belonging to a shared domain ConceptTypeByDomain Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4ret7qgOKgEdmAAAACs6hfSg" class="cyc_term">ConceptTypeByDomain</a> is a collection, all of whose elements can be considered concepts which belong to some domain of knowledge. For example, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rWJzeaOKhEdmAAAACs6hfSg" class="cyc_term">FamilyRelationsConcept</a> is the collection that includes predicates, such as <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjj6ZwpEbGdrcN5Y29ycA" class="cyc_term">siblings</a> or <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjPcJwpEbGdrcN5Y29ycA" class="cyc_term">children</a>, collections, such as <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjhG5wpEbGdrcN5Y29ycA" class="cyc_term">FamilyCohabitationUnit</a>, and potentially other concepts that are part of the domain of family relationships. It is important to note that instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4ret7qgOKgEdmAAAACs6hfSg" class="cyc_term">ConceptTypeByDomain</a> are not quoted collections -- i.e., their elements are not the _terms_ used to represent the concepts, but instead are the concepts themselves.

Every thing in the Cyc ontology -- every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaApwpEbGdrcN5Y29ycA" class="cyc_term">Individual</a> (of any kind), every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvl2en5wpEbGdrcN5Y29ycA" class="cyc_term">Set_Mathematical</a>, and every <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAzJwpEbGdrcN5Y29ycA" class="cyc_term">Collection</a> -- is an instance of (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViA9JwpEbGdrcN5Y29ycA" class="cyc_term">Thing</a>.

(Note that the above reference to "every thing in the Cyc ontology" is not meant to be limited to things actually reified in the Cyc system, but includes (e.g.) every instance -- reified or not, known or not -- of every collection recognized by Cyc.)
