The Pembroke Coast Express^[1] was a named train operated by British Railways which began running in 1953 along with several other services, as a way of better promoting faster or more direct services. In 2006, the name was used by First Great Western to advertise its Summer Saturday service between London Paddington and Pembroke Dock.^[2]

Since 2006 First Great Western has operated the service between London Paddington and Pembroke Dock on every Saturday in the summer timetable. The up service from Pembroke Dock departs at 10:01 and the service from London Paddington leaves at 08:45.^{[citation needed]}
