In an ideal world, I'd like to see
- the whole glass monolith 2001 thing swept away and the north shed opened up to the light like the south one.
- station facilities knocked through into the adjacent part of the North Western Hotel (the floor below at street level could be used as well)
- an open mezzanine installed with unintrusive coffee places, bars etc along the wall of the hotel building continuing into the south shed
- the passage between the (new) platforms 5 and 6 opened up and re-used for passenger facilities
- the area of and alongside the former platform 1 (including the void alongside the cutting wall), the old travel centre, the old taxi rank beside Lord Nelson Street, and the space under the multi-storey car park freed up for passenger facilities
- the taxi rank moved out onto Skelhorne Street (the taxis don't need to be under cover, as long as there's a covered space at the edge of the station adjacent to there they pull up), and the space inside used for something more useful
- a much less cluttered concourse
- a better-lit and less shabby subway down to the Merseyrail station entrance
- staff facilities and offices moved to the office block on Lord Nelson Street.
There's maybe not the space for facilities on the scale of Piccadilly, but there's no reason why Lime Street couldn't be as attractive and well-served as, say, Glasgow Central or Newcastle
