The driver of South West Trains' 159009 has a clear road in front of him at Templecombe, Somerset. The Salisbury to Exeter route is mostly single track but the next ten miles to Yeovil Junction are double track so trains can pass easily, even if one is running late. The up line (on the right) is signalled for trains to run in either direction but this train will be taking the usual route along the down line which is signalled for only that direction.
