Iron ore mining is primarily a mechanised large-scale activity, but some small-scale manual mining does occur. Small-scale mining uses simple manual tools such as pick …

Here is the 32 car iron ore train at Dr. Rivet's layout. It is too long for my layout. The ore cars started off about three inches apart. In real life the wheels from one car almost touched the wheels on the next car. Something had to be done to get close coupling. I created quad units like the DM&IR.

India's iron ore production slowly gains traction, expected to touch 276.4Mt by 2025. After several years of growth, India's iron ore production fell by 14.4% to 199.5Mt (million tonnes) in 2020. This fall was primarily due to 18.3% lower output from the state of Odisha, which accounted for 51.9% of the total production.

In contrast, the third type of ironworks was small-scale and widespread in areas lacking major iron ore deposits, and manufactured implements through the recycling of scrap iron. These ironworks were considered to be privately owned and took the form of production units 4 operated by workers who were mostly members of the …
