Alright C, They've tarted the station up a bit mate, so when you come out the main entrance it can be a bit confusing. Anyway, the main entrance is now in Stephenson Street, if you step outside you'll soon get your bearings. Just across the road, to the left is size? go past that, turn left and keep going. That pedestrianized area will take you straight to the big fountains and town hall. Head towards the town hall, follow it round to the right and the museum is there on the right.
