Something which I've tried before on "Railway General Knowledge"; but previous attempts were seemingly rated, in the main, unacceptably abstruse and "way-out". Attempting same again, but hopefully framed more accessibly ... around peak-time in these islands for mileage of railway operational for passenger services (early 20th century); there were a fair number of instances of two different stations in the British Isles with identical name; but serving places in different parts of the islands, and often on lines of different companies.
The question covers six of such, shown below. There are given, the name of the pre-Grouping railway company which served the station; the county in which located (past, and present, status thereof, are catered for); plus a clue of some sort, re each pair. Some of the stations concerned, still have a passenger service today; info re those in that category, shown in bold.
Re each of these same-name pairs; please furnish the name.
(1) Midland & Great Northern Joint Railway -- Norfolk
LB&SCR -- West Sussex
Name shared with the surname (Christian name Michael), of a not terrifically well-known, or successful, 16th / 17th century poet.
(2) GWR -- Cornwall
Great Eastern / Great Northern & Great Eastern Joint -- formerly Huntingdonshire, now Cambridgeshire
Name associated with a favourite silly rhyme / riddle: well-attested to be about only one of these two communities !
(3) Furness Railway -- Lancashire
North Staffordshire Railway -- Staffordshire
Name potentially evocative of romantic times-long-ago fantasy stuff a la Tolkien; including a precious metal, with such associations.
(4) Great Southern & Western Railway (Ireland) -- County Kildare
GWR -- Monmouthshire (Gwent)
The Irish location has an Irish-language name; but is more often referred to by the shorter English-language one which is sought. Re said name, reference can be envisaged to a novel gap-spanning undertaking.
(5) GWR -- Oxfordshire
GWR -- North Devon
One was on a lengthy terminal branch line of the GW; the other, on an -- also long -- secondary route, junctions both ends and en route, of the company. Both lines (a considerable distance apart, in England) now totally abandoned.
(6) Great Northern Railway -- formerly Huntingdonshire, now Cambridgeshire
North Eastern Railway -- East Riding of Yorkshire
Name brings to mind -- with the stations, one letter less -- a very famous fictional practitioner of rigorous logic and deduction.
