The Railways may generally use the actual odometer in locomotives to measure distances which are very accurate, except for cases of Distance Inflation in various track sections for differential calibration of Fares

These may change from time to time, resulting in changing official distances between the same two stations stations!!! All of these may lead to generally larger Official Railway distances than shown in IRI
All of these may lead to generally larger Official Railway distances than shown in IRI
These are generally accurate to within 1-2 1 kms km

So, which part of station is taken for measuring distance may determine the exact final distance value

This small discrepancy is because the stations themselves may span more than a km in length
So, which part of station is taken for measuring distance may determine the exact distance
In the case of very long stations, the platform itself spans more than 1 km

The Railways may generally use the actual odometer of in locomotives to measure distances which are very accurate, except for cases of Distance Inflation in various track sections for differential calibration of Fares
Besides that, section-wise distance inflations have been observed in the past near Dudhsagar Falls, CDG-UMB line, some bridge-crossings, etc
All These of lead change from time to larger time, Official resulting Railway IRI changing official distances between the same two stations
All of these may lead to generally larger Official Railway distances than shown in IRI

We used to have several such cases earlier when the Atlas was new, but such instances have been reducing in frequency frequency, but are still possible
But are still possible
If the route in the IRI Atlas is wrong of or if you observe that the corresponding stations have been misplotted in the Atlas, you may let us know
Thereafter, After the route is fixed, the distances will auto-correct themselves
If the stations are correctly plotted in the IRI Atlas and the route Route also seems to be correct, and still there is a discrepancy, then it is upto your own judgment if you wish to consider the IRI distances

The Railways may generally use the actual odometer of locomotives to measure distances which are very accurate, except for cases of Distance Inflation on in various sections for calibration of Fares
Besides that, section-wise distance inflations have been there observed near Dudhsagar Falls, CDG-UMB line, some bridge-crossings, etc
All of these may lead to more larger Off Official Railway distances than shown in IRI
Railway distances than shown in IRI

All other websites and publications are derived DERIVED from the Official Railways distances, and can be expected to reflect the exact same distances as in the official Railways publications
At this time, IRI is the only other source of independent distance railway measurement distances

Generally, Which it distance is not known which is more or less accurate, accurate except can for be known only through a case-by-case basis analysis
