What are Rational Formulae? What is Maflin’s Formula? What is the Special Committee Formula?

19-07-2019

These are various formulae for calculating the gang strength required to perform maintenance of different kinds on a section of track. Maflin's Formula, adopted in 1931, is a very simple one (number of gangmen = 2.5 x 'unit per mile' x length of track, where the 'unit per mile' factor depends on the kind of traffic carried on the track). It assumes a standard requirement of manpower regardless of the track gauge. The Revised Maflin's Formula was adopted in 1962 following the recommendations of the Lobo Committee in 1959. In this, rather than using the length of track directly, the length is specified in Equated Track Miles (ETM), which depends on traffic density, type of track formation

The three-tier system divides responsibilities for track maintenance as follows: 1. On-Track Machines (OMU). Mechanized maintenance (see above) including systematic tamping, intermediate tamping, shoulder ballast cleaning, ballast profiling and redistribution, track stabilization, and periodic deep screening of ballast. 2.

Does IR use mechanized means for track laying and maintenance?
July 19, 2019

IR has used some track-laying equipment, but much track is still laid manually. A lot of track maintenance is also done manually, with a veritable army of gangmen that are out 'on the line' to inspect track and fix problems. There is, however, a big push to mechanize track maintenance -- the target being complete mechanization by 2012. Tie

What is ‘through’ or ‘scattered’ renewal?
July 19, 2019

Complete Track Renewal (CTR) refers to the most thorough track replacement regime where rails, sleepers, etc., are fully replaced. Through Rail Renewal (TRR) refers to the replacement of rails in a given section of track, while Through Sleeper Renewal (TSR) refers to the replacement of sleepers. Similarly, there are Through Turnout renewal (TTR),

What is ‘beater packing’? What is included in the maintenance carried out by gangs commonly seen on the tracks?
July 19, 2019

The most common system of routine manual (non-mechanized) track maintenance is known as through packing or beater packing (from the name of the tool used for packing ballast, a 'beater'). This includes the following steps: Opening of the road : ballast is unpacked, fittings and fastenings of the rails loosened Examination of track : Rails,

How is track maintained?
July 19, 2019

Permanent way maintenance is largely done by gangs consisting of gangmen under the supervision of a gangmate. The gang goes down its assigned section of track (the gang beat or beat section), inspecting track and performing normal routine maintenance. A patrolman may be separately deputed to perform visual inspections along the length of a section
