<P> The middle pair of platforms is numbered 3 & 4 . The former is used by similar trains to platform 1, but platforms 4 - 6 do not have access to the lines from Exeter Central . Instead platform 4 is the main platform for inter-city trains to Paignton, Plymouth and Penzance . Trains from both platforms 1 and 3 can also reach this route so trains from Exmouth that continue westwards will reverse in one of these platforms . </P> <P> The third platform block sees northbound trains to London Paddington and the North use platform 5 . Various local services use platform 6 as do trains from Paddington or the North that terminate at Exeter then return northwards . </P> <P> Beyond platform six is the Exeter panel signal box that controls not just St Davids but also the main line north through to Taunton & Cogload Junction and southwards to Totnes & Torquay as well the branches out to Exmouth Junction and Crediton . Next to this is Exeter Traincare Depot where DMU sets used on local services are fuelled . A goods shed is situated beyond Red Cow Crossing at the north end of the platforms, and finally beyond that is Riverside Yard which still sees goods traffic . Cowley Bridge Junction is about a mile away at the far end of Riverside Yard, but the junction for the Exeter Central line is right by the south end of the platforms . This line curves eastwards and climbs steeply to cross a small viaduct before entering a tunnel beneath the city; the main line instead stays on the level and crosses both the River Exe and the city's flood defence channel before curving gently out of sight . </P> <P> Exeter St Davids is the busiest station in Devon, handling around 100,000 more passengers each year than Plymouth by 2015, when just over 2.5 million journeys began or ended at St Davids . Comparing the year from April 2007 to that which started in April 2002, passenger numbers increased by 30% . </P>
