Furthering its plans to expand the railway network in the United Provinces, O&RR built two branch lines connecting the Benares-Lucknow loop in the Ganges (Ganga)- Gogra (Ghaghra or Saryu) doab.
| Name of Railway Company | Name of railway line | Origin-Destination | Section | Distance in miles | Date of Opening |
| Oudh & Rohilkand Railway ( O&RR) | Allahabad Fyzabad Branch | Allahabad- Fyzabad | Fyzabad-Sultanpur | 35.5 | February 1,1904 |
| O&RR | Allahabad Fyzabad Branch | Allahabad-Fyzabad | Sultanpur-Siwait* | 47.05* | July 1,1903 |
| O&RR | Allahabad Fyzabad Branch | Allahabad-Fyzabad | Siwait-Phaphamau | 3.27 | January 20,1904 |
| O&RR | Allahabad Fyzabad Branch | Allahabad-Fyzabad | Phaphamau-Allahabad | 7 | January 1,1905 |
The first was a line connecting Allahabad and Fyzabad (Faizabad and now known as Ayodhya Cantt) via Phaphamau, Pratabgarh (Pratapgarh) and Sultanpur. This line met the Moghalsarai- Lucknow- Saharanpur main line at Pratabgarh.
The 2.45 mile stretch between Pratabgarh and Chilbila situated on the main line was used as a common railway line for trains on the main line as well as the branch line. Pratabgarh and Chilbila became junction stations.
After Chilbila, the line veered away in the northeasterly direction towards Sultanpur. This line brought Sultanpur into India’s railway map for the first time. After Sultanpur, the line continued in the same direction to finally terminate at Fyzabad. With this connection, Fyzabad became a junction station. The branch line was completed after the opening of the Curzon bridge in 1905.
There were two major bridges on the Fyzabad branch. The first one was the Curzon bridge over the Ganges between Prayag and Phaphamau stations of the Allahabad-Phaphamau section of O&RR.
Just after Sultanpur, the second major bridge on the Fyzabad branch was constructed by O&RR over the river Gomti. [In the future, Phaphamau was slated to become a major railway junction with four routes emanating in the shape of trident- one towards Unao/ Rae Bareli , two towards Fyzabad, three towards Jaunpur via Janghai and Zafarabad and four towards Allahabad via the Curzon bridge]
| Name of Railway Company | Name of railway line | Origin-Destination | Section | Distance in miles | Date of Opening |
| Oudh & Rohilkhand Railway (O&RR) | Allahabad Jaunpur Branch | Allahabad–Jaunpur | Phaphamau-Mariahu via Janghai | 47.51 | June 18,1906 |
| O&RR | Allahabad Jaunpur Branch | Allahabad-Jaunpur | Mariahu-Zafarabad | 10.67 | January 1 1907 |
The second branch line on the Benaras-Lucknow loop connected Phaphamau to Jaunpur via Janghai, Mariahu and Zafarabad.
With the completion of this line in 1907, Janghai which was situated on the Moghasarai- Lucknow- Saharanpur main line became a junction station. In addition, Zafarabad on the Benares-Lucknow loop also became a junction station.
| Name of Railway Company | Name of railway line | Origin-Destination | Section | Distance in miles | Date of Opening |
| East Indian Railway (EIR) | Lucknow-Sultanpur-Zafarabad branch | Lucknow- Zafarabad | Utratia-Hydergarh | 27.75 | March 31,1931 |
| EIR | Lucknow-Sultanpur-Zafarabad branch | Lucknow- Zafarabad | Hydergarh-Sultanpur | 51.58 | March 31,1932 |
| EIR | Lucknow-Sultanpur-Zafarabad branch | Lucknow- Zafarabad | Sultanpur-Zafarabad | 56.78 | May 25,1932 |
By May 1932, East Indian Railway ( which had by then taken over O&RR) built a chord line between Lucknow and Zafarabad to enhance rail connnectivity. The line veered away from Utratia near Lucknow via Sultanpur ending finally at Zafarabad Jn. With the opening of this line, Sultanpur and Zafarabad became four way junctions while Utratia became a three way junction.
Now, Benares was connected to Lucknow via three routes- one via Rae Bareli main line ; two via Sultanpur chord line; and three via Fyzabad loop. The chord line was the shortest distance between Benares and Lucknow while the loop line on which Ayodhya was situated was the longest.
