Getting back to the Daldy, I agree a bit of coal is not going to make a difference to climate, these old girls do have a use by date where the costs just get to much though: It needs drydocking bi-annually at a cost of 200-250k, it uses about a ton of coal an hour to run (350 a ton?) If they can get the support why not keep her going? Steam gives a lot of pleasure to people, Glenbrook is very popular
