Status of Train Speeds over Indian Railways
General The average speed of freight train is steady and unchanging for the last 20 years as per the published figures of Indian Railway. It was 22.8, 24.1, 25.6, 23.4 and 23.8 in the Year 1990-91, 2000-01, 2010-11, 2015-16 and 2016-17 (till Oct.2016). Had IR reached the plateau of the target average speed? Is there […]
IR to improve its mobility of freight train by revisiting Newton First law and make sure non-stop running of freight train for a target of minimum 4 hours. Every railway man has a strong want to see Indian Railways succeed in its mission to be a national transporter of passenger and freight at most economical cost. Transport on rail […]
Wheel was invented around 4000 BC; and two wheel cart followed immediately for transportation of goods. It was soon noticed that harder and smoother surfaces provides ease in transportation. As the loads become heavier, four wheeler carriage took shape. The track become straighter and harder. Efficient transportation system started on rail only, whether it was a horse driven carriage or steam traction at the beginning of the 19th century. It was for the reason that resistance to haul on rail is much less as compared to road. But with the development of petrol/diesel/gas engine, road transport became the most preferred mode of transport because it offer house to house connectivity. Competition between different mode of transport such as air, rail, road and sea starts taking shape.
Travelling Speed has always fascinated Engineers irrespective of mode of transport and Railways is no exception. Railways were the first to arrive at the scene of transport but it is the speed by air and convenience of end to end travel by road which shifted preference away from the Railways. Development of Railways then focused on speed for short […]
Time Corridor is the time period specified during the 24 hour interval for a specific activity of running trains of similar maximum and average speed . The activities are Running of fast coaching trains Passenger trains Freight trains Maintenance corridor There are certain observations made watching train operation to derive this concept of time corridor Train bunching takes place during […]
There were three types of trains over Indian Railways up to 70s namely Mail, Express and passenger trains. Mail and Express trains were either overnight or two night-one day journey. Passenger trains stopping at stations were designed to cover a distance of 150-200 Km in 5-6 hours. Thereafter, different types of trains introduced but without any standardized features. Today, […]
