This was an original Walthers product line launched in 1990. Walthers SceneMaster offers scenery, lighting, figures, loads, vehicles, and other details like shipping containers to build a realistic model railroad. WalthersN offers locomotives and rolling stock in N scale. Walthers Controls offers electrical controls and wires for DC train layouts.
Walthers continued to make the Life-Like line of products, aimed at beginning hobbyists and the mass consumer market, up until the 2010s. The Life-Like train sets were discontinued in 2016, along with many of the stand-alone products, although currently building kits and grass mats are still sold under the Life-Like name.
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 ...
The definition of a closed loop control system according to the British Standards Institution is "a control system possessing monitoring feedback, the deviation signal formed as a result of this feedback being used to control the action of a final control element in such a way as to tend to reduce the deviation to zero." [2]
The modules are combined to form a complete switch or any of the modules can be added to your present Step-by-Step Systems.) EMS-2 (The EMS-2 RURAL SWITCH is a stored program control analog switch designed to be cost-effective in small exchanges. The modular design with connectorized cabling permits fast initial installation and growth.
A keyboard matrix circuit is a design used in most electronic musical keyboards and computer keyboards in which the key switches are connected by a grid of wires, similar to a diode matrix. For example, 16 wires arranged in 8 rows and 8 columns can connect 64 keys—sufficient for a full five octaves of range (61 notes).
The crossbar switch itself was simple: exchange design moved all the logical decision-making to the common control elements, which were very reliable as relay sets. The design criteria specified only two hours of downtime for service every forty years, which was a large improvement over earlier electromechanical systems.
The panel switch is an example of a power drive system, in that it used 1/16 horsepower motors to drive the selectors vertically to hunt for the desired connection, and back down again when the call was completed. In contrast, Strowger or crossbar systems used individual electromagnets for operation, and in their case the power available from ...
