Tanker 618 was delivered along with Sterling's Engine 611, a 2004 Pierce engine. It carries 1,250 gallons of water and is equipped with a 1500 gallon per minute pump. With the arrival of Tanker 618 (Mack/Pierce), this Pierce was listed for sale in June of 2011. With the planned opening of the Kincora Safety Center (Fire Station 24) in 2013, the decision was then made not to sell this Pierce and it was assigned as Engine 624 when the new station opened.
This unit was sold in 2015.
