'''Track Access Controller''' (known as TAC) is a [[life-critical system|safety-critical]] job role in the [[London Underground]]. TACs work mostly at night and protect workers in the track environment, during "[[Engineeringengineering]] hours" when [[Railway electrification system|traction current]] is switched off and passenger trains have stopped running. Using Line Safe and Line Clear rules, they protect engineering workers from traction current, as well as moving trains and vehicles.
