Railway Operations Management

My collaborator in this area is Prof Madhu Belur from Electrical Engineering, IIT Bombay.  A link to recent work in this area is maintained by him, at which has more details of work related to timetabling and capacity planning.

Current railway work is with post doctoral fellow in IEOR, Dr K.P.Anoop, doctoral student Swapnesh Subramanian, Prof Madhu Belur (Electrical Engineering, IIT Bombay) and external collaborators. 

A big project that we were recently involved with is with Indian Railways, in providing simulation based support for timetabling of passenger services on an important part of their network, the Golden Quadrilateral and Diagonals (GQD) - comprising the network between New Delhi - Howrah - Chennai - Mumbai, including the diagonals.  The work also includes planning of maintenance blocks and freight corridors on this network.


Railway collaborators from Indian Railways over many years have been K.N.Singh and R.Gopalakrishnan, and senior railway officers M.Ravibabu (now retired) and R.Badrinarayan.  An article I wrote in May 2020 about my long assocation with the Railways and in particular with the cadre of Indian Railways Traffic Service (IRTS) is here.  My sabbatical leave with Railway Staff College in 2000 and 2001 was facilitated by A.K.Srivastava, now retired from the IRTS.

A long time mentor has been Prof G.Raghuram, who was at IIM Ahmedabad and then IIM Bangalore.  More recently, Dr Siddhartha SenGupta and his colleagues from TCS have had a strong assocation with our railway activities.

Collaboration in Railway Operations and Public Transport planning are ongoing with the group of Anita Schöbel, who was earlier at the University of Göttingen, Germany and is now with Technical University, Kaiserslautern, Germany.

Earlier work

Recent projects and efforts have been with Central Railways (suburban timetabling and management of rolling stock), Western Railways (crew planning), RDSO (Lucknow) and TCS (Mumbai).  Crew planning for suburban services on Western Railway was done by M.Tech students Naman Kasliwal and S. Sudarshan, and crew planning for Mumbai division of Central Railway by M.Tech student Akshat Bansal.

A workshop was held on 21 June, 2019, on Suburban Rail Operations Planning, which was attended by Railway personnel from Central, Western, South Central, Southern, South Eastern and Eastern Railways and also Delhi and Bengaluru Metro Corporation.  The link to the workshop is at 

Earlier work was with RITES (Gurgaon) on analysis of the Mughalsarai Ghaziabad section of North Central Railway (with Madhu Belur), and earlier with Abhiram Ranade (Computer Science and Engineering) on Western Railway (Mumbai) on signal respacing,

A decision support system for managing the rolling stock for petroleum rakes on Indian Railways was developed by M.Tech student Vishal Rewari, with the active participation and support of the Directorate of Petroleum Movement on Indian Railways.  This was continued by students Sai Muni Teja and Abhirath Sharma.

Some links to earlier and ongoing work are below

  • Line Capacity Simulator, now being developed with Madhu Belur.  Many earlier students and project staff have contributed to this work, including Devendra Shelar, Soumya Dutta, Aayush Aggarwal, Anuj Sahu, Vipin Maurya, R.Vidyadhar, Peeyush Gupta, Ayush Agrawal, Abhishek Singh and Keshav Singh.
  • Timetabling for suburban railway operations, now being developed with Anurag Agarwal, Soumya Dutta and Madhu Belur.  Earlier students who have worked on this include Shashank Dangayach.
  • Modeling of nodes and terminal railway yards and stations, is being done as part of doctoral work of Shripad Salsingikar.  Former students Deepak Miglani, Sudhanshu Jha and Ashish Dogra have contributed to this work.
  • Rolling stock management for freight operations is part of the doctoral research of Tejas Ghorpade
  • Modeling the impact of terminal movements in timetabling and control of trains, is a joint project with the group of Anita Schöbel in Germany, with Sebastian Albert and Julius Pätzold.
  • A concept note on Railway Timetabling, with Madhu Belur, was completed for Niti Aayog.
