I believe Freezer admitted a great many of his plans were effectively impossible in the space dictated, many have curves that are far too tight by modern standards. Actual track standards were also quite different, which is something not always taken into account.
I recall one of his plans was redone in a railway modeller article or something similar, they added a good foot or two to length and width.
That said I regularly peruse the psl track plan book for ideas. One thing about a lot of Freezers plans is they are quite "packed".
Iain Rice took a more "railway in the landscape" approach which looks a lot more natural. Minories however has a pretty sleek look about itself, manages to look every bit the "complex station throat" of an urban terminus while maintaining functionality.
I think while my terminus may be Freezer my quays will be Rice!
