Heritage Park's working locomotives, Nos. 2023 and 2024, each have a water tender capacity of 3,000 gallons. When in use, one of these engines will travel approximately 72 kilometres in a single day on the track at Heritage Park and use between 1,600 and 1,700 gallons of water.
Every morning, the engine being used is filled up from this water tower. Heritage Park built this enclosed water tower and tank in 1973 from a 1902 Canadian Pacific Railway plan. Pipes and valves for the tower came from a retired water tank at East Coulee, Alberta, 22 kilometres east of Drumheller.
