| India's 1st dedicated railway test track is being constructed in Rajasthan | | |  Agencies
NAWA, RAJASTHAN, Nov 10: A dedicated railway test track is being constructed in Rajasthan to develop the facility for testing rolling stock. This track will be completed by December 2025. The country's first train trial track in Rajasthan is almost ready. This 60 km long track is not completely straight but many curved points have been made. With this, a trial can be taken of how the train coming at speed will pass on the curved track without reducing the speed. In these curves, some curves are made for lower speed and some are made for high speed. After the completion of the first phase, bullet trains can also be tested at a speed of 230 kmph. The establishment of the country's first dedicated test track will establish new dimensions in the testing of high-speed rolling stock items in the country and this test track will prove to be a milestone in the direction of the railways moving towards modernity.
Along with strengthening the infrastructure, special emphasis has also been given to protected rail operations by the Railways in the past. Apart from the railway track, rolling stock plays an important role in strengthening safety. Before using the rolling stock, it is necessary to test it extensively and intensively, only then it can meet the safety criteria.
The railways will be able to use the resources extensively and safety will increase significantly through the dedicated test track. For the comprehensive testing of high-speed rolling stock in the country, the Indian Railways is developing the country's first RDSO dedicated test track of 60 km between Gudha-Thathana Mithdi in Nawa of Jodhpur Division, Deedwana district of Rajasthan. This railway track has been drawn from the middle of Sambhar Lake which is about 80 km from Jaipur. The work of the RDSO dedicated test track has been approved in two phases. Phase 1 work was approved in December 2018 and Phase 2 work in November 2021. The total estimated cost of this project is Rs 820 crore.
The construction of the dedicated test track includes seven big bridges, 129 small bridges and four stations (Gudha, Jabdinagar, Nawan and Mithadi). 27 km of work has been completed under this project and the target has been set to complete the entire work by December 2025. Comprehensive testing facilities of high-speed rolling stock and items including speed tests, stability, safety parameters, accident resistance, quality of rolling stock etc. are being developed under this project. This dedicated test track also includes testing of track material, bridges, TRD equipment, signalling gear and geotechnical studies. Different structures like bridges, under bridges, and over bridges have been built on the track.
RCC and steel bridges have been built on this track which are below and above the ground. New technology has been used to make these bridges vibration-resistant. The response of a train passing over it at high speed can be tested through these bridges. The bridge has been built using a turn-out system. That is, stainless steel has been used on top by installing heavy RCC boxes. Since the environment of Sambhar is alkaline, the steel will not rust. Also, the vibration of the high-speed train can be reduced. The speed will be tested by passing the bullet train through these structures. This will be the first dedicated track in the country where neighbouring countries will also be able to get their trains tested. |
