History
File:Lartigue, Ballybunion, 1900.jpg
This most unusual wheel arrangement was only used for specialised monorails.
=Listowel and Ballybunion Railway=
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.{{cite book |last1=Newham |first1=A.T. |last2=Foster |first2=Michael |title=The Listowel & Ballybunion Railway |year=1989 |orig-year=1967 |publisher=Oakwood Press |location=Headington |isbn=0-85361-376-1 |id=Locomotion Papers LP33 |pages=46, 65 }}

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.{{cite web|url=http://www.indianexpress.com/news/rail-trail-patiala-state-mono-rail-tramways/362660/ |title=RAIL TRAIL: Patiala State Mono Rail Tramways |date=18 September 2008 |publisher=Indian Express |access-date=12 September 2010}}
Also, in the Russian notation that counts axles instead of wheels, 0-3-0 is identical to Whyte's 0-6-0.
