LNER 60007 Sir Nigel Gresley - English Riviera Express through Dawlish 

Thank you.

Those luxury excursions are only steam hauled for part of the excursion as they often have multiple boarding points and it is used to haul the coaches out the way at the destination to allow the steam locomotive to turn around without hauling the whole train around a reversing loop (few working turntables left now) and allow it to be bunkered and watered with the coaches off being serviced/cleaned and restocked for the return. The carriages and some locos are privately owned by a rail tour company. Other locos are hired/borrowed from collections and preservation societies.

Dawlish Warren?
