Safe steaming
K3+D FA*70-200mm lens

I recognise that as a long shot taken by you standing on "The Cob" and having ridden the line from Porthmadog to Blaneau FFestiniog, I don't think you reach a tunnel until much higher up.
I like the immediacy of the head-on view and the wisps of steam you have captured.
