a monorail track comprising a plurality of rail assemblies each connected to at least one other of said rail assemblies and each comprising an upper rail member having an upper surface, sides, opposite ends, and a bottom surface, a narrow middle rail member, said middle rail member being connected to said bottom surface of said upper rail member, said middle rail member having a lower surface and lower side surfaces, a plurality of upright rail supports, said rail supports being attached around said lower surfaces and said lower side surfaces of said middle rail member, each of said rollers on each of said roller arm subassemblies being positioned during operation of said engine assembly to engage one of said sides of said upper rail members, one of said rollers on each of said safety arm subassemblies being positioned during operation of said engine assembly to engage one of said sides of said upper rail members and at least one of said rollers on each of said safety arm subassemblies being positioned during operation of said engine assembly to engage said bottom surface of said upper rail members, a plurality of electrically conductive strips, at least one of said electrically conductive strips being positioned on said upper surface of each of said upper rail members; means to connect said ends of adjacent ones of said upper rail members to one another and said ends of adjacent ones of said middle rail members to one another to form said monorail track so that electrical current can be transported from said electrically conductive strips on one of said upper rail members to said electrically conductive strips which are attached to the one of said upper rail members next adjacent thereto, a direct current power source; a sufficient quantity of wiring to electrically connect said electrical pick-up subassemblies to said direct current motor and said electrically conductive strips to said direct current power source so that when said engine assembly is positioned upon said upper surface of said upper rail member, said electrical pick-ups contact said electrically conductive strips to draw power therefrom to move said engine assembly along said monorail track; at least one car assembly having a car shell, a car base, at least two of said safety arm subassemblies, and two wheel-coupler subassemblies each comprising at least one of said rollers, one of said wheel-coupler subassemblies on each of said car assemblies comprising a male coupler for attachment to said female coupler on said engine assembly, each of said wheel-coupler subassemblies also comprising at least two of said rollers for movement of said car assembly along said upper surface of said upper rail members and a pivot point to allow said car assemblies to move along curved sections of said rail assembly, said safety arm subassemblies each having a plurality of said rollers to center said car assembly upon said upper rail member and a plurality of said rollers to engage said bottom surface of said upper rail member to prevent said car assemblies from becoming separated from said monorail track at speed; wherein said drive subassembly also comprises a pinion gear connected to said direct current motor, an upper tooth gear connected to said pinion gear, five interlocking gears connected between said upper tooth gear and two of said rear engine wheels which counter-against said sides of said upper rail member to drive said engine assembly along said upper surface of said upper rail member, one reduced-sized engine wheel for support of said engine assembly upon said upper surface of said upper rail member, and means to bias said two rear engine wheels against said sides of said upper rail member to account for wear of said two rear engine wheels during use; a plurality of switches, each of said switches having an incoming upper rail member and two outgoing upper rail members, each of said outgoing upper rail members having an outside edge, a swivel track member having opposite sides and positioned adjacent to said incoming upper rail member, a gap separating said swivel track member from said incoming upper rail member, said swivel track member having a pivot point, a swivel support member supporting said pivot point, each of said outgoing upper rail members supported on a switch support member, a switch stop connected to said outside edge of each of said outgoing upper rail members near to said swivel track member and positioned to engage said swivel track member when said swivel track member is selectively pivoted so as to align said electrically conductive strips on said swivel track member with said electrically conductive strips on the one of said outgoing upper rail members to which said swivel track member becomes pivotally aligned, an electromagnet laterally connected to each of said switch support members, and a metal plate connected to each of said opposite sides of said swivel track member in a position for selective attraction to one of said electromagnets so that an engine assembly positioned on said incoming upper rail member can be transferred for movement onto a selected one of said outgoing upper rail members; said system further comprising at least one building associated with said monorail track, each of said buildings having a plurality of openings therethrough each of said openings sufficiently dimensioned to house one of said engine assemblies positioned upon one of said upper rail members, and further supported by one of said middle rail members; wherein each of said electrical pick-up assemblies comprise an electrical pick-up having an upper portion and a lower portion, an electrical pick-up guide positioned over said upper rail member to guide said electrical pick-ups along curved sections of said rail assembly, a weight positioned above said lower portion of said electrical pick-up and in contact therewith to bias said lower portion of said electrical pick-up downwardly against said electrically conductive strips on each of said upper rail members, said weight being supported by said electrical pick-up guide, said electrical pick-ups also each having a pivot point positioned between said upper portion and said lower portion for help in moving said electrical pickups horizontally along curved sections of said monorail track, said electrical pick-ups each being connected to an attachment block attached to said engine base which allows vertical movement of said upper portion of said electrical pick-up relative to said upper rail members;
