With model railroads, changing track layouts on the table, on the floor or outdoors are quite common. Frequent mating of the track connectors can cause them to become loose and/or dirty and can result in higher contact resistances. If a short circuit event occurs in combination with higher contact resistances, there is a risk that your control panel/booster will not detect the short circuit quickly enough, but will continue to supply a high current. This high current can lead to uncontrolled heating and thus to the outbreak of a fire.
A frequent feeding of the traction voltage into the track bypasses the transition resistances that have to be overcome, the automatic shutdown of your command station/booster reacts faster and safer.
