There seems to be only one station with “North” as a prefix:
While North is transliterated into Hindi, the word Uttor in Assamese is used.
Due to space constraints, the name in English is written as a single word.
Also in Assam there is
where North is transliterated into both Hindi and Assamese.
In the vicinity of Visakhapatnam there is
Here, the word for North is a prefix both for Hindi and Telugu.
Next to Coimbatore:
Interesting. The Tamil word Vadakku is used here, which is then transliterated into Hindi. There are several better-known instances like this in the Chennai area.
In Kerala, there is Vadakara (formerly Badagara).
The word Vadaka is North in Malayalam. However, the place name may not have intended to say this.
There are a few others like this in Tamil Nadu and Kerala.
Still in Tamil Nadu:
It is easy to check that the station and locality are “North”. However just the initial for N is used in all three languages.
Finally, this station was known as Ernakulam North from the time it was opened in the late 1930s until the late 1950s.
Local people still habitually refer to it as North station, which can cause problems to outsiders who do not know this. Like the case of Cantt station for Varanasi Jn.
Kalupur for Ahmedabad and Nampalli for Hyderabad are different cases since these stations never officially had these names.
