I'm glad to see that the Dilton Marsh platform is to be extended.
I counted no fewer than 22 getting off the 15:28 from Warminster there about 10 days ago ... it seems it's the regular school train home. And I also walked past the station on the Wessex Ramblers winter walk, as was struck by how housing development on on side continues to encroach on the station, and how close the village is not the other side.
To my (potentially incomplete) knowledge, there's not been any recent study, nor are there resources waiting around for one, to see what would happen if the 'curious and perverse' service were to be replaced by something a little more frequent, and a little less peversed. But I've just got a sneaky feeling we might see a passenger increase quite out of proportion to the service increase. Whether that would merely be abstraction from Westbury, or new traffic, would be a very interesting question to consider!
