Mechanised Track Laying Speeds Up DFC Project


Speeding up the track laying work, 1.56 km long track was laid with the help of the New Track Construction (NTC) machine, a new working procedure, on the Khurja-Dadri section of the Eastern Dedicated Freight Corridor on Wednesday.

With the aim of completing the DFC project by 2021, DFCC has done away with the manual way of track laying and accordingly deployed seven such state-of-the-art machines in both the Eastern and Western corridors.

Ensuring safety, the Rs 70 cr NTC machine, successfully laid the track with the precision in the section amid the presence of senior officials of Indian Railways and Niti Aayog, who had gone to the site for inspection.

Appreciating the use of latest technology in laying track, Niti Aayog Vice Chairman Rajiv Kumar said the operation of the DFC would act as a crucial multiplier for the Indian Economy.

Efforts are on to revive the economy despite the pandemic and railways have a crucial role to play for it, Kumar added.

Entire track laying of the DFCC is being undertaken by the NTC machine which has the capacity to lay 1.56 km track per day as against a maximum of 400 to 500 metre through manual process.

The Khurja-Dadri Section is the connecting link between the Eastern & Western Dedicated Freight Corridors having the capacity to run heavy haul and long haul freight trains at 100 kmph.

DFC is very important for us and the project is going to be completed by 2021, Chairman Railway Board (CRB) V K Yadav said after the inspection of the automatic track laying procedure.

DFCC Managing Director AK Sachaan along with other senior officials were also present during the mechanised track laying operation undertaken by the US-made NTC machine.

The 60-metre long NTC machine is being operated through remote control with involvement of five skilled operators and 12 workers.

In the Eastern DFC, 4 NTC machines are deployed in the Allahabad – New Bhaupur, Allahabad–Pandit Deen Dayal Upadhyaya junction, Bhaupur–Bhadan, Khurja-Dadri sections and in Western DFC, 3 NTC machines are deployed at Palanpur-Makarpura, Gothangam-Baroda and Anchali-Sachin sections respectively.

We are planning to engage NTC machines for laying tracks in Indian railways also, said CRB.

NTC machines bring substantial ease and efficiency in track construction with integrated logistic arrangements for mechanized handling, movement and laying of heavy track components. The machine provides continuous action assembly line kind of laying with high speed and accuracy.

These machines not only accelerate speed of construction but also help in careful handling and placement of rails and sleepers, achieving high initial quality in track laying.

It is a well known fact that the initial quality of track laying determines its performance and service life.

Laying tracks using the continuous-action, assembly-line method has proven to be the most cost-efficient method of work. The entire supply of new sleepers and rails within the track being laid is by mechanised operation.

According to DFCC, accuracy and high working speed are the outstanding features of this technique. The higher output of this continuous working action is the greatest advantage compared to cyclic action using gantry units. Other advantages are the careful handling of the material, particularly the rails, and better preparation of the subsoil (sleeper bed).

DFC is one of the largest rail infrastructure projects undertaken by the Government of India. The overall cost is pegged at Rs 81,459 crores.

In the first phase the organisation is constructing the Western DFC (1504 Route km) and Eastern DFC (1856 route km) spanning a total length of 3360 route km. The EDFC starting from Sahnewal near Ludhiana (Punjab) will pass through the states of Punjab, Haryana, Uttar Pradesh, Bihar and Jharkhand to terminate at Dankuni in West Bengal.

The Western Corridor connecting Dadri in Uttar Pradesh to Jawaharlal Nehru Port (JNPT) in Mumbai will traverse through the states of UP, Haryana, Rajasthan, Gujarat and Maharashtra of WDFC. EDFC & WDFC (excluding the Sonnnagar – Dankuni PPP section) will be completed by Dec 2021.
