Nutfield sounds even funnier in English :gossip:
Except it's not nutfield at all.
First of all these are the names of two different municipalities (one is Noisy-le-Grand, the other is Champs-sur-Marne). Since the station is at the border of both municipalities, it is called "Noisy-Champs").
Then Noisy, Nuciacum in Medieval Latin, has nothing to do with nuts (nux/nucis in Latin). That's a folk etymology. The more likely origin is much more typical and mundane: the name of an ancient Gallo-Roman landlord (the name "Nautius" has been suggested), with the typical Gallo-Roman place ending -acum, which, in the Paris Region, ended up being pronounced and written -y (hence the many place names ending in -y in the Paris Region).
This -acum ending was found all across Celto-Roman Europe, it gave -y in the Paris Region, it gave -og in Wales, -ack/-ick in Cornwall, -ach and -ich in Germany (the city of Jülich for example), -ik/-ijk in Flanders, -ac in Southern France (which is why what the French know as Tolbiac the German know as Zülpich, it's the same place, Tolpiacum in Latin, with typical t>z evolution in German, and -acum>-ich evolution, whereas the French name is not based on the Paris Region dialect, hence the reason why it kept a form closer to Latin, whereas in the Paris Region it would probably have become something like Touchy). Another example is the frequent Gallo-Roman place name Campaniacum (estate (-acum) of Campanius), which gave Kempenich in German, Champigny in the Paris Region dialect, Campigny in coastal Normandy (where the hard c of Latin was preserved, whereas the Parisian dialect softened it into ch, hence castle in English vs château in French, since the English word is based on coastal Normand dialects whereas the French word is based on the Parisian dialect), Campagnac in Southern France, closest to Gallo-Roman as always, Champagné in Western France, etc.
As for Champs-sur-Marne, it is the very frequent Gallo-Roman place name "Campus", which means countryside, cultivated lands, and this particular one is the "cultivated lands upon the Marne river".
Noisy-le-Grand was the seat of a royal residence during the Merovingian kings, hence the moniker "le Grand" (to distinguish from Noisy-le-Sec, which was originally called Noisy-le-Petit).
Champs-sur-Marne has a beautiful 17th century château which was built by two successive landlords who were among the financiers financing the wars of Louis XIV. The first one almost ended up in the Bastille for embezzlement, but died just before his arrest warrant was issued. As for the second one, he was also accused of embezzlement after Louis XIV died in 1715 and had his properties confiscated by the Regent.
That's what's fascinating about all these Parisian suburbs. They all have a great history behind.
The park of the Château de Champs is beautiful and freely accessible to the public. It extends down the hill all the way to the Marne river.
