I am a transport planner believe me !! Panipat RRTS was given priority over Alwar RRTS due to low or poor connectivity between Delhi and suburb like Murthal Narela Rai Sonipat smalkha Gannaur !!! and yes Panipat.

Industrial Characteristics of Panipat which is majorly known as Weaver or handloom town also does not actually generate high traffic/travel demand as compared to other service industries !!!
