Below is a reprint of a photo from the March 1961 issue of Headlight, New York Central's employee magazine. It shows a jet snow blower moving west, being pushed by an 8200-series Alco RS3 and clearing Track 2 at Scarsdale NY on the Harlem Division on January 23, 1961. This was the original unit -- powered by a surplus B-36 jet engine mounted on a caboose frame -- and is not the same as the one pictured above. That is a later model.
I believe this snow blower was built at Collinwood Shops around 1960. Normally it worked clearing yard tracks in freight yards but January 23rd (a Monday) was not a normal day. New York Central train service had been shutdown after striking New York Harbor railroad marine workers (ferryboat and tugs) had thrown up picket lines at various terminals and Central crews refused to cross them. Operations were shutdown for seven days beginning on January 17, 1961. The picket lines came down on January 23rd but in the meantime a heavy snowfall had dumped close to a foot of snow on Central tracks. With no trains running it was a real mess. Thus the call went out for the jet snow blower.
The snow blower cleared the main tracks but reportedly problems were encountered in the yard at Putnam Jct. (Brewster). At the time employees said the blower -- which did not melt snow but literally blew it away -- did create some condensation and the following morning some of the switches were frozen up.
Other Central employees have told me the blower (probably one of the newer models) was used at Dewitt Yard in Syracuse several years later following a monster snow storm. That time the problem was the snow blower was picking up things like discarded air hoses and brake shoes and whipping them around. The track engineer in charge finally had to order the blower operation be discontinued before someone got seriously hurt.
