The overall idea is an urban terminus loosely in the style of something like Broadstone, Galway or Sligo, with a good amount of passenger workings and freight in off peak.
Minories was designed around loco hauled commuter trains (specifically steam hauled) rather than DMUs.
The idea of the throat is twofold, allowing all platforms accessed from either road and to eliminate reverse curves, while also providing an interestingly complex looking throat without actually being too complicated.
Part of that is the lack of crossovers, the station pilot must release the trapped loco from the end of the platform. That said I may have a crossover line off platform 3 to facilitate shunting.
