CR wants to build a mega outstation train terminus complex at Parel, had received this year\u2019s budget allocation of Rs.193 crore<\/strong><\/p>\n

\"\"MUMBAI:<\/strong>\u00a0Work on one of the most ambitious projects, of building a mega outstation rail terminal at Parel that will change the face of the city, has gathered momentum after budget announcement with the first step taken \u2013 Central Railway has an issued letter to the Railway Board for the closure of the 139-year-old Parel workshop with an elaborate action plan to shift its activities elsewhere.<\/p>\n

With Mumbai CSMT saturated and LTT station too out of the way for passengers on the Western Railway, CR\u2019s idea to build a mega outstation train terminus complex at Parel in South Mumbai, at the site of the existing workshop, had received a boost in this year\u2019s budget with a fund allocation of Rs.193 crore. In the letter issued to the Railway Board a fortnight ago, CR has discussed in detail how the activities at Parel workshop could be distributed to other workshops before shutting it down.<\/p>\n

Passing the parcel<\/strong><\/p>\n

Originally, it was at Parel workshop that work on the maintenance of the new LHB coaches was proposed at a cost of Rs.88.14 crore; now kept on hold, and given the inadequate space at Matunga, the work is likely to be shifted to Nagpur. The work of maintaining the heavy 140-ton crane, diesel engines and accident relief and tower cars could be taken up at Ajmer, and the manufacturing of narrow-gauge locomotives that Parel used to do will be taken up at Kurduwadi, with the proposed work of maintenance of wagons at Kurduwadi shifted to Badnera.<\/p>\n

The new terminus at Parel will not only have passenger platforms, but also a huge maintenance yard for trains. It will be linked with the new fifth and sixth lines between Kurla and Parel, work on which is on. This is in addition to the work on Parel local train terminus, which too is underway.<\/p>\n

Rs.193 Crore:\u00a0<\/strong>Funds allocated for Parel train terminus complex project<\/p>\n

139 Years:<\/strong>\u00a0Age of the Parel railway workshop.<\/p>\n

This is the only workshop, other than the Diesel Locomotive Works and Chittaranjan Locomotive Works, which builds diesel locomotives.<\/p>\n

Humongous Machines \u2013 The Workshop Story<\/strong><\/p>\n

\"\"Indian Railways<\/strong>\u00a0that carry around 3 crores passengers every day has grown by leaps and bounds over the last 165 years. Indian Railways, which had a modest beginning in 1853, has since then been an integral part of the nation, making the country proud of manufacturing all the engines and coaches locally. To understand the activities taking place in Central Railway\u2019s Locomotive Workshop at Parel in Mumbai, It was visited the work spot recently; it took nearly 4 hours to cover the workshop and understand the activities taking place there.<\/p>\n

The Parel workshop, one of India\u2019s oldest railway workshops, diversified over the years, and, at present, is also carrying out the repair and overhauling of diesel locomotives, diesel cranes, and rehabilitation of mainline coaches. It also manufactures many components for diesel locos, carriages, and wagon. The workshop successfully manufactured narrow-gauge locos for the Neral-Matheran section and the Kalka-Simla section.<\/p>\n

Normally, each workshop is specialized in any one area \u2013 either coach building or engine manufacturing or refurbishing of engines and coaches. But the Parel workshop currently manufactures and overhauls broad and narrow gauge locomotives, carries out refurbishing and overhaul of coaches and 140-tonne accident relief cranes as well.<\/p>\n

History of Locomotive Manufacturing<\/strong><\/p>\n

The Parel Locomotive Workshop, established in 1879 as a steam locomotive repair unit, has now diversified and started manufacturing shunting type locomotives from 2007 by supplying it to Steel Authority of India Limited for their entire on-campus requirements.<\/p>\n

Later, it bagged orders from major power plants, ports, rail yards and logistics providers across the country and received orders for more than 190 locomotives. Till date, it has manufactured 155 shunting locomotives to become the largest manufacturer of such locos in India.<\/p>\n

The workshop also manufactures diesel locomotives for the hill railways. The first locomotive manufactured by Parel workshop ran between Neral and Matheran, a quaint hill station near Mumbai. The locomotive is uniquely designed to negotiate the sharp hairpin curves of the hills, by an articulated design inspired by the German Arn-Jung locomotives. It has 2 Cummins NT-495 model diesel engines with hydraulic transmission units manufactured by Allison Transmission. So far it has manufactured and supplied 23 locomotives to the hill railways.<\/p>\n

Under-Frame Construction<\/strong><\/p>\n

The entire engine and the driver cabin are fitted over the under-frame. The underframe is manufactured with the help of high-grade steel structure and joined by CO2 welding. CO2 welding is preferred in manufacturing locomotives since the weld metal will not be affected by oxygen and nitrogen in the atmosphere.<\/p>\n

After welding, the deposition efficiency is high and slag formation little, which makes it unnecessary to remove the slag after each cycle; this is the main reason why CO2 welding is preferred for underframe construction. After manufacturing the under-frame, the entire unit is transferred to the assembly line where other major components are fitted in.<\/p>\n

Bogey Construction<\/strong><\/p>\n

Bogies are considered the main part of a locomotive, as the wheelsets with the axle box and traction motors and suspensions are fixed in. Each locomotive has 24 primary suspensions, 16 secondary suspensions, and 8 vertical shock absorbers. The wheels and axles sourced from the Bonatrans Group are checked for nomenclature and finally painted and polished before going into the assembly line. Normally, all the trains run on steel wheels to bear the entire weight and reduce rolling friction.<\/p>\n

Once the wheelsets come into the assembly line, the axle box and traction motors are fitted. Each bogie has 6 sets of wheels, with individual traction motors and axle boxes. Each of its 6 wheelsets or 12 individual wheels drive the locomotive. But these massive 21-tonne bogies are not rigidly fixed to the frame of the loco; it has been constructed as body-on-frame chassis.<\/p>\n
