Train operator First Great Western is looking for customers to join a panel which will have a say on its services. Panel members, who need to be regular travellers with the firm, will be able to represent the views of customers with managers.
Successful applicants will be allocated a route to represent.
Lesley Colman, customer liaison manager, hopes the panel will help: "They really make a difference, giving customers a strong voice."
First runs trains services from London through the Thames Valley, the South West of England and the Cotswolds.
