Who is responsible for public transport / public transit services in Galway?

No one organisation is responsible for public transport in Galway, or any area in Ireland.

The Ministry of Transport is responsible for licensing commercially operated scheduled bus and ferry services.

The National Transport Authority (NTA) is responsible for
"securing the provision of public passenger land transport services. This includes the provision of subvented bus and rail services by Bus √Čireann, Dublin Bus and Irish Rail."
It is expected that the NTA will
"take over responsibility for the licensing of commercial bus services and the regulation of the small public service vehicle sector during 2010."

Galway City Council has a Transportation Unit. but its responsibilities are limited to the City area.  The unit is involved in a number of projects to improve the public-transport infrastructure in the city, and in planning for future services.

Local councils are consulted when bus-services are licensed, but the final decisions are made by the central agencies.

Local transport operators must obtain a licence for any public bus service tha the wish to run.  They are free to provide public information about their services, but are not required to do so.

GalwayTransport.info (GT.I) is a private initiative that aims to provide public information, for both residents and visitor, about public transport that is available in Galway. In general, it does not show information about planned changes until they are confirmed and have a clear start-date.
