Yes, as i always wonder when i move LDH Bye-pass towards Chandigarh & u find:
1. LDH-UMB Line @ Doraha
2. A brand new Rail Bridge Underpass: LDH-CDG Line
3. One Rail Overbridge, while bye-passing Morinda (after New Morinda that line comes): post amalgamation of LDH/Sirhind line, but before CDG bend
4....
more... One more Overbridge, still @ Morinda Bye-pass, after New Morinda & Morinda Jn bend towards CDG!!
PS: One more joint exist, which u may or may not follow while in CDG & thats amalgamation of UNA & Kalka Line, just before CDG!! All this criss-cross to provide smooth Freight movement, with no reversal, as passenger service for Sirhind/CDG-UNA & LDH-CDG is quite minimal!!
