Long Island 4-6-0 "Ten-Wheeler" Type Locomotives

Class G53 (Locobase 2969)

Data from 1899 Brooks catalogue.

Builder info from B.Rumary, 25 Kingscombe, Gurney Slade, Radstock, BA3 4TH, ENGLAND and Jeremy Lambert as supplied by Allen Stanley in March 2004. Works #3229-3233 in June 1899

Camelback freight engine with the wide firebox (10 x 8 feet) burning fine anthracite coal. The catalogue gives the engine's rigid wheelbase as 6 feet, which implies lateral driving-axle boxes at least on the lead axle and flangeless drivers.

Class G53 - simple (Locobase 5708)

The account in the April 1894 American Engineer & Railroad Journal compares this locomotive with #145, a 4-cylinder Vauclain compound. The table of trials shows that the safety valve on this simple-expansion engine was set at 145 psi while the compound's was set to blow at 180 psi. Wonder of wonders, the compound showed better fuel economy -- how much was related to using higher-pressure steam? The article doesn't say.

Class G53 - compound (Locobase 5709)

The account in the March 1894 American Engineer & Railroad Journal compares this locomotive with the simple-expansion #138. Charles M Jacobs, consulting engineer, found that this Vauclain compound version showed a 37.2% decrease in coal consumption and 17.2% decrease in water use. He doesn't comment on the higher boiler pressure used in the compound (180 psi vs 145 psi) and whether that difference might have affected the results. He does note that all of the runs took place in conditions "adverse to the compound engine."
