From the First Great Western press release:
New timetable means earlier and more frequent services for Devon and Cornwall
The Department for Transport has today agreed to the first significant redesign of First Great Western^s mainline timetable in Devon and Cornwall for over a decade.
The changes will see an improved service for the South West, providing an earlier morning direct service from London to Plymouth and Cornwall, getting to key destinations beyond Totnes 40 minutes earlier than today.
Answering the calls of local business, the proposals will deliver a much improved service for the region, supporting the generation of economic growth through improved connectivity between major centres.
Key improvements include:
^ The 0706 Paddington to Paignton service will now instead run to Plymouth and Penzance, arriving 40 minutes earlier at key stations from Totnes and beyond than the current first direct service from London. The 0730 Paddington to Penzance service will now instead run to Paignton.
^ Additional capacity for summer travellers on the late morning (1039) service from Plymouth through Cornwall by using an eight carriage High Speed Train rather than a smaller local train.
^ Faster mid-morning service between Paddington and Plymouth
Subject to approval by Network Rail, the new timetable will operate from December this year.
