What are the maximum speeds at which IR passenger stock runs?

22-06-2019

The typical maximum speed specification for passenger coaches in good condition is 100km/h. Older coaches and those in poor condition can be seen with annotations restricting their maximum speed to something lower, such as 80km/h. Rajdhani and Shatabdi trains and other fast trains of course have stock that can be hauled at higher speeds. The newer LHB design coaches (see below) can also be hauled at high speeds, 160km/h for the air-conditioned cars and 120km/h for the non-air-conditioned ones. Recently ordinary ICF integral coaches have been spotted occasionally bearing annotations for a maximum speed of 120km/h (e.g., on the Jammu Tawi - Howrah Exp.) ये भी पढ़े -

What determines where locomotives are changed for a train?
July 17, 2019

Locomotive changes often happen at convenient points where there is an appropriate loco shed where locos can be housed for a while and given some routine maintenance if necessary, etc. Except for long express services (for which keeping down the number of halts is a priority) hauled by WDM-2, WAM-4, WAP-4, WAP-5, and other such locos for which

What does it mean when a passenger or freight rake is referred to as a ’15/30′ load, or a ’36 unit’ load?
July 17, 2019

In order to compute the load to be hauled by the locomotive(s), IR personnel use some rules of thumb. An 8-wheeled passenger coach (of any kind) is counted as 2 units, a 4-wheeled wagon as 1 unit, 8-wheeled wagons as 2, 2.5, or 3 units depending on the payload capacity. A 36 unit load for a passenger train, therefore, may refer to 18 coaches each

What else is specified in the working timetable?
July 17, 2019

The working timetable has a lot of other operational details. It has the load table specifying what loads each kind of locomotive is allowed to haul on sections covered by the timetable. In addition to the schedules for trains including the make-up time, etc., as noted above, it sometimes has a crossing and precedence table that describes which

How is that trains that are delayed unexpectedly at some point (sometimes) still reach their destinations on time or nearly so?
July 17, 2019

IR provides generous amounts of make-up time or slack (also known as Extra Time Allowed (marked 'EA' in the working timetable), or margin) in the schedules for most long-distance trains. Delays of half-an-hour to a couple of hours are almost inevitable in the running of most long-distance trains (except the 'prestigious' ones such as the

What’s the ‘normal running time’ of a train on a section of track?
July 17, 2019

The normal running time of a train between two points (usually two stations) is defined as the time it takes the train to travel between those points at the booked speed allowed for that train on that section, with allowances for permanent or temporary speed restrictions in effect, the time for acceleration and deceleration between the stations,

What’s the ‘minimum running time’ of a train on a section of track?
July 17, 2019

The minimum running time of a train between two points (usually two stations) is defined as the time it takes the train to travel between those points at the maximum permissible speed allowed for that train on that section, with allowances for permanent or temporary speed restrictions in effect and gradients along the route.
