Crew members of two stationary steam engines will host a tour of the restoration operations at 3:30 p.m. July 16 at the National Museum of History, 511 E Third St. and the N.J. Transportation Heritage Center, Phillipsburg, N.J. The NMIH tour begins with the former York Water Company 103 year old horizontal steam powered water pumping engine. The equipment is 35 feet long, weighs 115 tons and pumped eight million gallons of water a day.

The tour will then carpool to the Phillipsburg, N.J. pump house to see Big Allis, a 1913 steam powered water pump. The three cylinder, two flywheel vertical engine, is rated for six million gallons of water a day and is 51 feet tall. It is surrounded by a complete steam plant with the original boilers, condenser and backup turbine.

Tickets may be purchased in person at NMIH. The proceeds will be split equally between the two restoration projects.
