The Indian Railways will implement the provision of 750V power supply for maintenance of Linke Hofmann Busch (LHB) rakes at washing/sick lines, South Western Railway officials said in Hubballi on Sunday.
In November 2016, the Railway Board took a policy decision to switch over 100% of its production to LHB coaches from April 2018. An energy review undertaken at the Railway Board showed that at 2021-22 base the diesel consumption on testing and maintenance of LHB rakes at washing and pit lines was about 1.84 lakh litres per day amounting to an annual recurring expense of approximately ₹668+ crore which was projected to increase at over 20% per annum, being a combined function of diesel prices and LHB fleet induction. Comparatively, grid electrical energy is 70% to 80% cheaper. This issue is typical to LHB and does not arise in ICF coaches, and therefore, infrastructure and capacity creation at washing/pit lines by providing 750V power supply for testing & maintenance of LHB rakes was important.
With this aim, capital works for 411 washing/pit lines on Indian Railways (IR) were sanctioned at a total capital cost of approx. ₹210 crore. It was a thrust area monitored by the Railway Board in a span of less than one year. Capital works were sanctioned and works awarded for infra creation at 411 washing/pit lines, covering entire IR and by end of July 2023, works at 316 washing/pit lines were completed. The rest are targeted for completion by Q2 of 2023.
