Nawa, Rajasthan:
A devoted railway take a look at observe is being constructed in Rajasthan to develop the power for testing rolling inventory. This observe can be accomplished by December 2025. The nation’s first practice trial observe in Rajasthan is sort of prepared. This 60 km lengthy observe is just not utterly straight however many curved factors have been made. With this, a trial might be taken of how the practice coming at pace will go on the curved observe with out decreasing the pace. In these curves, some curves are made for decrease pace and a few are made for prime pace. After the completion of the primary part, bullet trains may also be examined at a pace of 230 kmph. The institution of the nation’s first devoted take a look at observe will set up new dimensions within the testing of high-speed rolling inventory objects within the nation and this take a look at observe will show to be a milestone within the route of the railways shifting in the direction of modernity.
Together with strengthening the infrastructure, particular emphasis has additionally been given to protected rail operations by the Railways up to now. Other than the railway observe, rolling inventory performs an vital position in strengthening security. Earlier than utilizing the rolling inventory, it’s obligatory to check it extensively and intensively, solely then it might probably meet the protection standards.
The railways will have the ability to use the sources extensively and security will improve considerably by the devoted take a look at observe. For the excellent testing of high-speed rolling inventory within the nation, the Indian Railways is growing the nation’s first RDSO devoted take a look at observe of 60 km between Gudha-Thathana Mithdi in Nawa of Jodhpur Division, Deedwana district of Rajasthan. This railway observe has been drawn from the center of Sambhar Lake which is about 80 km from Jaipur. The work of the RDSO devoted take a look at observe has been authorised in two phases. Section 1 work was authorised in December 2018 and Section 2 work in November 2021. The full estimated price of this mission is Rs 820 crore.
The development of the devoted take a look at observe consists of seven massive bridges, 129 small bridges and 4 stations (Gudha, Jabdinagar, Nawan and Mithadi). 27 km of labor has been accomplished below this mission and the goal has been set to finish all the work by December 2025. Complete testing amenities of high-speed rolling inventory and objects together with pace exams, stability, security parameters, accident resistance, high quality of rolling inventory and many others. are being developed below this mission. This devoted take a look at observe additionally consists of testing of observe materials, bridges, TRD tools, signalling gear and geotechnical research. Completely different buildings like bridges, below bridges, and over bridges have been constructed on the observe.
RCC and metal bridges have been constructed on this observe that are under and above the bottom. New know-how has been used to make these bridges vibration-resistant. The response of a practice passing over it at excessive pace might be examined by these bridges. The bridge has been constructed utilizing a turn-out system. That’s, chrome steel has been used on high by putting in heavy RCC bins. For the reason that atmosphere of Sambhar is alkaline, the metal won’t rust. Additionally, the vibration of the high-speed practice might be decreased. The pace can be examined by passing the bullet practice by these buildings. This would be the first devoted observe within the nation the place neighbouring nations may also have the ability to get their trains examined.
The railways didn’t have any devoted line for the trials of coaches, engines and practice racks made in India. There’s a variety of visitors on all of the traces. In such a state of affairs, the schedules of many trains should be modified for the trials. Railway officers mentioned that not solely bullet trains but in addition high-speed, semi-high-speed trains, and metro trains can be examined right here in future. Excessive-speed, semi-speed and metro trains may also be examined on this observe. The workforce of RDSO i.e. Useful resource Design Customary Group of the railway will monitor the trial. This similar workforce the railway checks the health of the coach, bogie and engine. Earlier than placing any coach or engine on the observe, the railway checks each parameter to see if there can be vibration past the set pace. The response of the practice on a foul observe and many others. may also be checked. The high-speed devoted railway observe is 60 km lengthy, however the primary line is 23 km lengthy. It has a high-speed 13 km lengthy loop in Gudha.
The loop is used within the railway to cross the crossing or to permit two trains coming from reverse instructions to go with none interruption. Other than this, a fast testing loop of three km has been made at Nawa station and a curve testing loop of 20 km has been made in Meethadi. These loops have been made on curves of various levels. On a foul observe, the practice begins to wobble and jerk. If the observe will get broken, what must be the pace and what can be its results can be checked. For this, a 7 km lengthy twisty observe has been laid.
