To reduce the goods transportation cost and time, DFCCIL has introduced a 3300 km dedicated heavy load goods track for avoiding the congestion of existing passenger tracks which also opens up the opportunity to introduce new trains in the surplus time of existing routes.

The proposed heavy load capacity BG line will help faster movement of goods between East-West India and thus reducing goods carrying time and cost.

As a part of this 3300 km project we have been entitled to undergo geotechnical investigation of a 50 km stretch where we found the best route for tunnel and have completed geotechnical investigations to find tunnel profile and as an input to tunnel design.

The tasks performed during the project work are as follows

  • Reconnaissance Survey
  • GPS Survey for tunnel location finalization.
  • Demarcation of tunnel alignment.
  • Sub-Soil Investigation and Geological log preparation.
  • Laboratory test on soil and rock samples.
  • Calculation of RMR & other parameters.
  • Preparation of Soil investigation report.
