-A capacitor is a basic electronic component and can have many uses. Small value capacitors are often used in an electrical signal path to block DC voltage and only let AC signals/​voltages through. Small value capacitors may also be used with other components to make up filter circuits to pass or limit certain frequencies along a wire. Large value capacitors are often used for short term electrical storage or to smooth out AC ripple in power supplies that get their power from an AC input. ​ Combining several large capacitors, or using one or more “super” capacitors, may be used in a model railroad engine to provide momentary power when crossing parts of a track (dirty track or gaps in track for example) which would normally cause the engine to stutter or stop.  The common term “bypass capacitor” refers to adding a small value capacitor directly across the power and ground pins of an IC in order to help remove AC ripple or noise from the DC voltage used by the IC. +A capacitor is a basic electronic component and can have many uses.

 Capacitors can be made from may types of materials or processes such as mica, tantalum, polystyrene,​ electrolytic or ceramic. Each type has its uses and one type generally will not work in place of other types. Usually the type is called out on a parts list or schematic, or based on the value and tolerance, it may be assumed to be a certain type. Capacitor values are measured in “Farads”,​ generally microfarads (µF), nanofarads (nF) or picofarads (pF).     \\ [[:​glossary:​capacitor|Main article]] Capacitors can be made from may types of materials or processes such as mica, tantalum, polystyrene,​ electrolytic or ceramic.

-CARLOS is an acronym for Computer Aided Layout Operating System, a computer programme for creation of model railway control panels on screen. CARLOS is a DOS program developed by MERG member John Down and can be used with the Remote Panel Control (RPC) system. See TB G18/1 for more information. ​+CARLOS is an acronym for Computer Aided Railway ​Layout Operating System, a computer programme for creation of model railway control panels on screen. CARLOS is a DOS program developed by founding ​MERG member, the late John Down, it was designed to be used with the Remote Panel Control ([[glossary_r#​RPC|RPC]]) system. See TB G18/1 for more information

 +An adaptation of the program may be seen at the occasional model railway exhibition running the [[glossary_h#​Hysteresis loop|Hysteresis loop]] demonstration. Until recently running on a Windows 95 laptop, it now runs on a Raspberry Pi with a CEEEDTOP screen.
