  2. Digital model railway control systems - Wikipedia

    en.wikipedia.org/wiki/Digital_model_railway...

    Digital model railway control systems are an alternative to control a layout and simplify the wiring and add more flexibility in operations. A number of control systems are available to operate locomotives on model railways. Analog systems where the speed and the direction of a train is controlled by adjusting the voltage on the track are still ...

    A series of articles he wrote on building train control and signaling systems led to requests from other modelers that he began manufacturing them. The first ad (in the May issue of The Model Maker) offered a 24-page, 15¢ catalog that listed rail, couplers, and electrical supplies. Sales were over US$500.00 for the first year.

    Micro 'pizza layout' with 9 mm gauge track in 7 mm scale (09 scale) An important aspect of any model railway is the layout of the track itself. Apart from the stations, there are four basic ways of arranging the track, and innumerable variations: Continuous loop. A circle or oval, with trains going round and round. Used in train sets. Point to ...

    The Kato wiring accessories (e.g. Unitrack DC Extension cord, Unitrack 3-Way Extension Cord) are sufficient to power layouts that are three tables in length. For very large layouts, there is an updated standard of using a wiring bus similar to that which was developed by the T-TRAK Division of the North Virginia NTRAK club.

    C/MRI (Computer/Model Railroad Interface) is a set of electronic modules that allow a computer to monitor and control real world devices, including those used in conjunction with model railroads. C/MRI was first introduced by Bruce Chubb in the February 1985 issue of the Model Railroader magazine. It appeared again with a four-part series ...

    en.wikipedia.org/wiki/HO_scale

    HO or H0 is a rail transport modelling scale using a 1:87 scale (3.5 mm to 1 foot). It is the most popular scale of model railway in the world. [1] [2] The rails are spaced 16.5 millimetres (0.650 in) apart for modelling 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge tracks and trains in HO.
