You use Indian Railway for journey. You enjoy beautiful scenes and see your train changing tracks, and all of a sudden train sound changes a bit. You peek out of window and see that half of the train is over a bridge.
We can't vouch for all but we know many people has this thought in mind how safe is this railway bridge? Especially when train shakes a bit, lot more questions and thoughts start to pop up in head regarding railway bridges.
We are going to discuss about Indian Railway bridges here. Some known/ unknown facts.
Do you know how many railway bridges are there in India?
As of April 1, 2018 the total number of bridges in Indian Railway stands at 147253.
The bridges are categorized into 3 categories:-
1. Important Bridges: Railway bridges over 300 meter in length or those bridges which cover a total of 1000 sq metre of waterway (river, nallah, stream) come in this category. Apart from these, bridges which are earmarked as important by chief bridge engineers or principal chief engineer in terms of having problems, requiring more maintenance than others, and depth of waterway/ extent of river training works also come under this category. There are 700 of these important railway bridges.
2. Major Bridge: These are bridges of 18 metre or more length and have an opening of 12 meter or more in any one span. There are 12085 such major bridges.
3. Minor Bridge: Railway bridges which do not fall in above category are called minors. There are 134768 of these kind.
The above figure does not include Road Over Bridges (ROBs) which allow traffic to pass over underlying railway tracks. Also Foot Over Bridges (FOBs) which are set up at railway stations for common public to move from one platform to other are not considered as railway bridges.
However, It is interesting to note that Railway Under Bridges are considered as railway bridges as train pass over them.
Basically we can say that bridges that are meant for train movement and which in direct contact of railway tracks are called "Railway Bridges".
Coming back to thoughts popping up in mind about the reliability of a bridge as a train pass over it, the age of bridge is something that one really wants to know. Generally the newer the bridge, people perceive it to be much safer than the older bridge.
When train approaches really old bridges and if they tend to go slow as they move over it, few people start praying. There is some sort of fear. They think it may collapse. You also must have seen it.
How many railway bridges in India are over 100 years old?
