The fact that the operator calls it a halt? It's a common pattern on preserved railways to distinguish between "full service" stations catering to tourists (i.e. with a car park) and "only a halt" where the only expected customers are walkers.
Linley and Kirkhaugh are designated halts by the South Tynedale, Kingfisher by the Weardale.

But frankly, the definition of a halt is beside the point. My irritation is with overriding the work done by local mappers based on individual opinion. It doesn't sit well with a collaborative project.
