Java Model Railroad Interface (JMRI) is an open source program for model railroad hobbyists, released under GNU General Public License v2. It allows users to control LED lights, horn, or switch the railway of hobbyist open-source or commercials closed-sourced trains. JMRI is a suite of tools distributed via a single download.
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 ...
Digital Command Control (DCC) is a standard for a system for the digital operation of model railways that permits locomotives on the same electrical section of track to be independently controlled. The DCC protocol is defined by the Digital Command Control Working group of the US National Model Railroad Association (NMRA).
RailTopoModel is a systemic data model for describing the topology-based railway infrastructure as needed by various applications. The RailTopoModel has been initially developed under patronage of the International Union of Railways (UIC) and was released as International Railway Standard (IRS) 30100 in April 2016. [1]
Märklin Digital was among the earlier digital model railway control systems. It was a comprehensive system including locomotive decoders (based on a Motorola chip), central control (Märklin 6020/6021), a computer interface (Märklin 6050), turnout decoders (Märklin 6083), digital relays (Märklin 6084) and feedback modules (Märklin s88/6088).
In terms of model railway operation, gauge 3 is the largest (standard gauge) scenic railway modelling scale, using a scale of 13.5 mm to the foot. The Gauge '3' Society represents this aspect of 2 + 1 ⁄ 2 -inch gauge railway modelling with both electric and live steam operation.
Data modeling during systems analysis: In systems analysis logical data models are created as part of the development of new databases. Data modeling is also used as a technique for detailing business requirements for specific databases. It is sometimes called database modeling because a data model is eventually implemented in a database. [4]
Fixed track parts, rolling stock, scenery, building, tree and hills similar to a real life model railway. Users can also control the trains once the virtual railway is built and planned, leading to some people to call HVR a train simulator. Some advanced parts such as turntables are absent from the game, and all engines on the same track will ...
