A new bus timetable will come into force from Monday.
Changes include a summer evening service between Peel and Port Erin on the first Friday and Saturday of each month from July until October.
The new timetable will also see the return of an extra late night owl (01:15am) every Friday and Saturday.
There will also be a reintroduction of the Route 28 (the Sound via Cregneash) as well as services covering Niarbyl, Sloc and Ballamodha.
The Route 3 Sunday service, which serves Douglas to Ramsey via Laxey, will also run every 30 minutes through summer.
As a result of Castle Street in Castletown being temporarily one-way, the route between Douglas and Port Erin will alter slightly, with buses leaving Douglas as usual but arriving in Port Erin slightly later.
The TT timetable has also been published with extra services being offered making it easier for visitors and residents to watch the races and explore the Island over the two-week period.
