As we know, Rishi Sunak was born in Southampton, England. His parents earlier lived in East Africa. And one or both grandfathers were from Gujranwala in West Punjab.
So it is a little odd to find a place named Sunak in a particularly isolated place in Aravalli district of Gujarat.
It lies on the Himatnagar-Dungarpur section of the Ahmedabad-Udaipur line. This section was opened in the mid-1960s on metre gauge, and reopened on broad gauge in late 2022. This is about 118 km from Ahmedabad and 180 km from Udaipur. The line is presently served by a single pair of express trains, which do not stop at many stations including this one.
According to reports in Gujarati papers, the station was originally called Sunokh and was recently renamed to Sunak.
(Naturally, his ancestors from Gujranwala would have no reason to travel here).

This picture was taken in 2016 when metre gauge trains were still running.
Now see this article in a recent Gujarati newspaper, with a current picture of Sunak station on broad gauge:

If you can read Gujarati, the gist seems to be that the station was renamed recently when the line was converted. On the face of it, this seems to be true.
However, I have looked at timetables going back to 1994 and have seen the station was listed as Sunak and never as Sunokh. This is not the only case where the name in the timetable does not match with the actual sign at the station. This has been commented on by many researchers, such as the indefatigable Jim Fergusson. In fact, the Fergusson station lists also show that it was always listed as Sunak in timetables going back to the 1960s.
I would think that the station was originally supposed to be called Sunak but the painter for some reason painted it as Sunokh. Supervision of small things like this is often lax. Finally someone must have noticed this and changed the sign when the new line was opened.
Hope that someone forwards this to 10 Downing Street, before someone starts claiming that the Sunak family was actually from Gujarat.
