Ballastless tracks to facilitate operation of high-speed trains

The Indian Railways will switch to ballastless tracks on seven routes, including the Chennai-Bangalore sector, identified for operating high-speed trains, said A.P. Mishra, Member, Engineering, Railway Board, on Friday.

“Ballastless tracks that allow operation of high-speed trains and have the benefits of lower maintenance requirements and increased service life are the choice by default for these high-speed rail corridors, tunnelling projects and tracks near platforms,” Mr. Mishra said.

He was speaking to reporters on the sidelines of a two-day technical symposium on improving rail and rail welds and evolving appropriate design for ballastless tracks hosted by the Institution of Permanent Way Engineers (IPWE).

Feasibility studies are at various stages of completion on the high-speed routes, including Chennai-Bangalore, Delhi-Mumbai and Delhi-Chandigarh sectors.

According to Mr. Mishra, new tracks would have to be laid for the Chennai-Bangalore route where the plan is to operate trains at speeds in excess of 250 km per hour. The average speed on the Delhi-Mumbai route, where existing tracks are being used for trials of high-speed trains is about 200 kmph.
