Abstract: A system which operates a digitally controlled model railroad transmitting a first command from a first client program to a resident external controlling interface through a first communications transport. A second command is transmitted from a second client program to the resident external controlling interface through a second communications transport. The first command and the second command are received by the resident external controlling interface which queues the first and second commands. The resident external controlling interface sends third and fourth commands representative of the first and second commands, respectively, to a digital command station for execution on the digitally controlled model railroad.

Abstract: A vehicle for electric toy and model trains with a freight car body, which is suspended in a free-floating fashion over overrunning inclinations at superstructures of the carriages passing through its bottom in such a manner, that the pivoting angle is positively controlled proportionally by the rotation of the carriages when passing through curves, in the case of a carriage, the superstructures and the freight car body being provided with curve grooves or suspension pins, which engage the curve grooves and are disposed horizontally and transversely to the longitudinal axis, and that the other carriage is not guided and is hooked in a self-aligning fashion to the freight car body.

Abstract: A monorail toy train is suspended from an overhead guideway, which guideway is secured to a ceiling or other fixed support structure. The elongated tubular guideway includes a plurality of guideway sections connected together at a joint by a short tubular coupler and a hanger secured to the ceiling. Each guideway section is connected to like length guide rails and rack rails, which, together, define a track for cars of the monorail toy. Trucks of driven and nondriven cars ride on the track defined by the rack rail and guide rail. The driven car includes a drive frame including a motor, drive gear and pinion gear, which pinion gear meshes with the rack rail to provide motive force for the monorail train.

Abstract: A motorless toy vehicle and propelling track. The toy vehicle includes a gear housing having a drive system, the drive system including a drive gear and a ratchet means for controlling the direction of rotation of the drive gear. The track is adapted to receive and laterally direct the toy vehicle as it passes there along and includes a rack coextensive with the track having upwardly disposed teeth there along which operably engage with the drive gear. A rack drive reciprocates the rack back and forth in the track interacting with the ratcheted drive gear to propel the toy vehicle in the direction determined by the position of the ratchet means. Hill and switch tracks are also provided.

Abstract: A driving device for rail vehicles having both a friction drive and a cog gear drive has a common drive shaft placed in the longitudinal direction of the rail vehicle. The drive shaft is provided with driving worms which mesh with worm gears on the driving axles of the friction drive and the cog gear drive. The worms are axially spaced on the drive shaft and engage the respective drive gears of the friction and cog gear drives which are located under the drive motor so as to obtain greater traction force with the friction drive and a more positive meshing of the cog gear with the rack.
