If you're taking a train from NZM towards Mathura/Agra and you have got a window seat towards the left, DO NOT attempt to take your hand out at least for the first 5-10 kms. The poles and over-bridge supports are placed dangerously close right after NZM. The clearance between the coach and those poles is negligible. Also applies to RFs trying to doorplate on the left hand side. Beware.
