Many of us have heard of the short story of this name, written by Saadat Hasan Manto. If you need to refresh your memory, you can read it here:

The fact is that Toba Tek Singh was not a joke (as some may think) and is now a district town in Pakistani Punjab. It was part of Faisalabad (ex-Lyallpur) district earlier.
It is, indeed, named after a Sikh who lived there long ago and is still remembered.

It is on the Shorkot Cantt-Faisalabad section, not on the main line. But this route has trains connecting with Karachi, Lahore and Rawalpindi.
Here, we see railfans exploring this station and its surroundings. (Urdu with English subtitles):

Even I was fascinated to learn that there is an actual station of that name when I came across that video a few days back. Quite an interesting piece of trivia. A few of the railway stations in rural Pakistan are very clean and without any overhead electrification, semaphore signals still being used, it is as if some places are still living in the nostalgic bygone era.
