The teenagers have started a petition for their campaign
Two teenagers are campaigning for extra train services to north Pembrokeshire.
Joanne Griffiths and Sam Faulkner are aiming to persuade businesses, tourism operators and others to back their call for greater use of Fishguard station.
The 15-year-old friends say there is only one train a day in daylight hours to the port which coincides with the ferry crossing to Ireland.
The Welsh assembly government said it was actively considering plans to boost rail services to the area.
The youngsters have set-up their own website complete with video explaining what their campaign is about.
Sam said they had collected 130 signatures for their petition in a short space of time and aim to gather many more.
"Most are people who would use this service regularly or have friends and family who frequently come to visit on a train," he added.
"Fishguard station is much closer, quicker and easier to get to than Haverfordwest, Carmarthen or Clunderwen for people who live in rural North Pembrokeshire.
"This is something in which we believe and would make regular use and we are sure others would too.
"This service would also open up North Pembrokeshire, a region that relies heavily on tourism, to holiday makers and day trippers."
Joanne added: "It would be much easier to see friends because some do live quite far away, taking the train would be much easier for us."
The North Pembrokeshire Transport Forum said five or more shuttle services a day between Carmarthen and Fishguard were among the top rail priorities in the regional transport plan submitted to the assembly government.
It hopes the petition would help demonstrate support for the services.
An assembly government spokesperson said plans to improve train services to Fishguard and north Pembrokeshire were included in a report submitted to it last week.
"We will now consider all the regional transport plans and make a decision for approval by the end of this year," they added.
"As set out in our draft national transport plan, we are committed to developing a sustainable transport system for Wales and improving public transport to provide a real alternative to the car."
