Chheoki is at a distance of 10 km from Prayagraj Junction on the Howrah–Delhi main line.

Trains that bypass Prayagraj Junction and which come from Jabalpur and go towards Mughalsarai usually stop at Chheoki.

To reduce the load on the main junction, trains were shifted to Chheoki.

[4] The station was constructed to decongest Prayagraj Junction and provide a separate route for trains to southern India and Jabalpur which originate from eastern India and Mughalsarai.

This allows trains on the New Delhi–Howrah route to run punctually since scarce platform space at Prayagraj Junction is freed up.
