time taken by rajdhani from delhi to mumbai
Mumbai Rajdhani Express The 12951/12952 Mumbai Rajdhani Express is the fastest train on the Mumbai - Delhi sector and the fastest Rajdhani train as well as the fastest train (Considering ARS and including halts) in India. Mumbai Rajdhani Express is the first Rajdhani to get Alstom-LHB Coaches in India.[5][6] It used to run six days a week until September 2000 after which Railways decided to run it daily.[7] In its early days, it used to cover the distance of 1385 kilometres in each direction in 19 hours and 5 minutes. However, after the electrification of the route, the speed of the train improved[1] and as of 2016, it takes 15 hours and 35 minutes when operating as train number 12951 at an average speed of 89 km/h (including halts) while on its return journey as train number 12952 takes 15 hrs 50 mins at an average speed of 88  km/h (including halts) thus making it the fastest train on the Mumbai - Delhi sector.[8] Before the introduction of the LHB coaches, the maximum speed that could be attained with the conventional rakes was 120 km/h.But after introduction of LHB rakes the highest speed could attained is 160 km/h but is restrictred to 135 km/h due to poor conditions of tracks.[9] After their introduction, the LHB coaches enhanced the speed of the Rajdhani to more than 120 km/h and even touching 135+ km/h at times.[2] The highest attained speed is 140 km/h between New Delhi and Mumbai Central. Recently Vasai-Vadodara-Godhra Section top speed is enhanced from 120 km/h to 130 km/h. Hence, Mumbai Rajdhani's time reduced from 16 hours to 15 hr 35 minutes while it continues to be the fastest train in India (including halts) with average speed of 91 km/h.It is the first train (along with 12953/54 August Kranti Rajdhani Express as both have Rake Sharing) to be experimented with HOG (Head On Generation) which powers the train directly from locomotive instead of an EOG or generator van.
Urban rail transit in India There are currently 11 operational rapid transit (also called 'metro') systems in ten cities in India. As of November 2017, India has 425 kilometres (264 miles) of operational metro lines and 347 stations. A further 500+Â km of lines are under construction. Metro rail lines in India are composed of mainly standard gauge. Projects like the Kolkata Metro and Delhi Metro used broad gauge for their earliest lines but all new projects in India are on standard gauge as rolling stock imported is of standard gauge.
