It's been going on since the early autumn. Apart from creating a bottleneck in the pedestrian entrance below the platform pictured above, the works spill onto the roadway outside, with a three-way set of temporary lights in operation. This has also taken out the usual bus stop used for rail-replacement buses, and a few weeks ago when the Copy Pit line was closed at weekends, we spotted a crowd of people waiting for the RRB on the main A646 in the town centre - right on top of a pelican crossing!
Does anybody know what the eventual plan is here? Platform 1 in the above picture is already accessible on the level via the car park entrance, it is the other platform (Leeds-bound) that currently has no access from the subway other than steps.
