Day 098/17. 34052 Lord Dowding crossing the Hamble

Crossing the Hamble River on its way towards Weymouth, this newly restored vintage steam locomotive is on a day trip along the south coast full of enthusiasts.
Built in December 1946, Lord Dowding was one of the first members of the ‘Battle of Britain’ class of locomotives. During her career Lord Dowding was used on both passenger and freight trains across the Southern region before being retired in July 1967, one of the last steam engines to be retired by British Railways.
I'm just slightly disappointed that the required white plume of steam was missing. Is that because it is coasting downhill or because its warm and sunny?
