South West Trains plan to introduce new direct services to Weymouth on Saturdays in the summer. It hopes to boost tourism by providing trains from North Dorset, Somerset and Wiltshire.
They also hope they'll be an additional weekday morning service from Yeovil Pen Mill to London Waterloo.
Consultation is currently taking place with local authorities, communities and rail user groups about the proposals which would be introduced in May.
The summer trains would run on Saturdays and Bank Holiday Mondays from 21 May through to 3 September and help to provide a boost for communities, local businesses and tourism throughout the summer months.
