The train is a small world moving through a larger world - Niraj Kumar

Thanks for noticing. Yes, the Atlas infrastructure has been completely overhauled. The base map is now specifically tailored to IRI, focusing on and highlighting Tracks and Stations, rather than extraneous details like rivers, buildings, hotels, etc. This makes the Atlas light-weight and fast-loading - requiring low bandwidth and minimal processing power. As you zoom into the map, you will see more stations coming into the map - corresponding to the resolution. All tracks and stations are visible directly in the Atlas - visibility depending on the location/zoom level. You may click on any station or track, to view further details. You may also use the Station/Track filter boxes to zoom directly into the Station/Track. A Satellite view switch will also soon be added for seamless switching between map and satellite views.

All the previous info is also present. As for concerns regarding the borders of J & K, country shape info is acquired from the OpenStreetMap project which, like Wikipedia, is a world-wide, collaborative open community. (see Pic #3). Our members are free to go to OpenStreetMap and alter the shape of India, and the same will also thereafter be reflected in IRI.

Coming up soon:
1. Much more railway/IRI information - Bridges, PRS Counters, RF Spots, Our member favourites, will be incorporated directly into the base Atlas.
2. A completely Hindi version of the base Atlas.
3. A colourful Zone Map/Division Map - edited by our members - will be added to the Base Atlas.
4. Metro Maps will be directly added to the base map, and will be available through filters at higher zoom levels.
5. Station schematics showing platforms, junction points, etc. will also be directly added to the Atlas.
6. A light-weight completely offline version of the map will be available on the IRI mobile app - RailCal. The same can be used for Trip Diaries.
