First Great Western's 43186 helps propel its train up the stiff climb out of St Davids station towards Exeter Central. The usual route to London is closed for engineering work so this train from Plymouth to London Paddington has reversed at St Davids and will now run up the South Western route to Yeovil Junction before turning north to reach its usual route at Castle Cary.
