A thrust reverser actuation system comprising: a moveable transcowl assembly with a slider assembly comprising a slider cam and a slot; and a track lock assembly comprising: a pawl assembly comprising: a pawl arm extending from a pawl axis to a distal end configured to engage the slot in the slider assembly and contact a slot end of the slot, a cam arm extending from the pawl axis radially opposite the pawl arm and having a pawl cam, and a compliant member configured to urge rotation of the pawl assembly about the pawl axis from a pawl locked position, such that the distal end of the pawl arm is engaged in the slot and is positioned to contact the slot end upon movement of the slider assembly and the pawl cam is disengaged from the slider cam extending from the slider assembly, to a pawl unlocked position such that the distal end of the pawl arm is biased away from the slot to a position that does not interfere with movement of the slider assembly and the pawl cam is biased toward contact with the slider cam extending from the slider assembly; and a position lock assembly comprising a first lock arm extending from a lock axis and an actuator configured to urge rotation of the first lock arm between a lock locked position and a lock unlocked position, the first lock arm configured to engage and retain the cam arm in the pawl locked position when the first lock arm is in the lock locked position and disengage the cam arm in the lock unlocked position such that the compliant member is able to urge the pawl assembly to the pawl unlocked position. a moveable transcowl assembly with a slider assembly comprising a slider cam and a slot;
