Running costs for Island buses, railways and trams were nearly £15million during the 2017/18 financial year.
The figure - which also included central costs - was revealed by Infrastructure Minister, Ray Harmer MHK, in the House of Keys on Tuesday.
It came as part of a response to a question for written response from Onchan MHK Rob Callister.
Mr Callister had asked what the running costs were for those services for each year since 2012.
