"For it to work they will have to build two new platforms and means to cross the tracks"
There is little doubt that the current station is beyond repair. The platforms are wasted, the decking is rotten and the bridge is heavily corroded.
The new station is required to be accessible to disabled people so that will mean either ramps as well as steps serving the footbridge or expensive to maintain lifts on either side of the bridge. The height of the bridge will have to be raised to accommodate future electrification of the line.
All good for photos again when the sun gets round on an afternoon unless there are officious parking restrictions.
