List of key statistics of Northern Railways. Very nice, printable chart. Came across this when I was looking up the ruling gradient between CDG and KLK.
Some highlights.
* In terms of passenger footfall, Delhi division dominates with 29.75 Cr passengers annually.
*...
more... The steepest grade is undoubtedly the 1:40 section between Chandigarh and Kalka. Honourable mentions include the 1:75 grade between Laksar and Dehradun.
* The 1432 metre long Tawi bridge is the longest in the zone.
Also check out the yearwise statistics in the top right.
One curious thing that I saw here. It lists Delhi DAL and GAL as separate things. Are these different lines? I thought these were synonyms for the avoidance line from Okhla to Patel Nagar with the picturesque grade separated merge near Mayapuri. If someone could clarify, it'd be awesome.
