0-3-0
0-3-0 is a type of wheel arrangement for a monorail steam locomotive.History
This most unusual wheel arrangement was only used for specialised monorails.The Lartigue Monorail locomotives used on the Listowel and Ballybunion Railway were of 0-3-0 wheel arrangement, although they also required non-load-bearing guide wheels. These locomotives were built by the Hunslet Engine Company, Leeds in 1888.Four locomotives were built with this wheel arrangement in 1907 for the Patiala State Monorail Trainways, a monorail line in Patiala, India. They had double flanged driving wheels and the locomotives had an outrigger wheel that ran on the ground. The builder was Orenstein & Koppel of Berlin, one locomotive is preserved in working order at the National Rail Museum, New Delhi, New Delhi.
Also, in the Russian notation that counts axles instead of wheels, 0-3-0 is identical to Whyte's 0-6-0.
