Antacids work by counteracting (neutralising) the acid in your stomach. They do this because the chemicals in antacids are bases (alkalis) which are the opposite of acids. A reaction between an acid and base is called neutralisation.This neutralisation makes the stomach contents less corrosive.ntacids may be used: 1  To reduce the symptoms of acid reflux which may cause heartburn or inflammation of the gullet (oesophagitis) . 2  These conditions are sometimes called gastro-oesophageal reflux disease (GORD). 3  To relieve some of the symptoms caused by ulcers in the stomach and part of the gut called the duodenum.
HowTo/Configure An Interlocking Tower. An Interlocking Tower (aka Signal Tower) is an in game object which automatically configures junctions, signals and level crossings to allow trains to drive a path from one location to another.
Interlocking towers came about due to a need to centralize early railroad signaling systems at busy locations. Before the tower gained widespread use a signalman would have to manually set each signal and/or turnout (switch) to the desired indication. Not only was this very time consuming it was also very costly.
