Bul­let train will con­sume more power than Metro

NEWDELHI: In­dia’s first su­per­fast bul­let train, which will con­nect Mum­bai and Ahmed­abad, will con­sume 30% more elec­tric­ity than what the en­tire Delhi Metro net­work re­quires, ac­cord­ing to an es­ti­mate by the Na­tional High Speed Rail Cor­po­ra­tion Lim­ited (NHSRCL), which is ex­e­cut­ing the project.

NHSRCL said the project, once op­er­a­tional, will re­quire 1,100 mil­lion units of elec­tric­ity per year to power the train and the sta­tions it will stop at. In com­par­i­son, Delhi Metro, which runs on eight lines span­ning 350 kilo­me­tres serv­ing 236 sta­tions and con­nects the cap­i­tal with satel­lite towns like Gu­ru­gram and Noida, con­sumes 850 mil­lion units per an­num.

Of­fi­cials said this dif­fer­ence in con­sump­tion is be­cause bul­let trains need to at­tain a cer­tain speed — much higher than what a metro train is ca­pa­ble of — and be­cause metro trains de­ploy re­gen­er­a­tive brak­ing, a tech­nol­ogy that re­cov­ers some en­ergy while stop­ping and con­verts it back into us­able elec­tric­ity.

Ac­cord­ing to NHSRCL, ap­prox­i­mately 350 kilo­me­tres of trans­mis­sion lines and high volt­age ca­bling would be con­structed in Gu­jarat and Ma­ha­rash­tra for the bul­let train, for which the foun­da­tion stone was laid by Prime Min­is­ter Naren­dra Modi and Bul­let trains will hit speeds of 350k/hr, whereas metro rains reach a max­i­mum of 60-70k/hr

Metro trains also de­ploy tech that gen­er­ates elec­tric­ity while brak­ing, and these trains brake much more fre­quently

The in­tro­duc­tion of the coun­try’s first bul­let train, known as the Shinkansen in Ja­pan and ex­pected to be op­er­a­tional in 2022, will mark In­dia’s shift to an era of high­speed trains ca­pa­ble of hit­ting speeds of up to 350 kilo­me­tres per hour. Train 18, which will con­nect New Delhi and Varanasi, hit a top speed of 180 kilo­me­tres per hour dur­ing a test run in De­cem­ber, and is billed as In­dia’s fastest train.

NHSRCL has al­ready tied up with power gen­er­at­ing com­pa­nies, which will sup­ply the 1,100 mil­lion re­quired per year to power the in­au­gu­ral bul­let train.

Power re­quire­ment will grow as the num­ber of train ser­vices in­creases in 2033, 2043, and 2053.
