Both Circar and Chennai kakinada express are regularly parked all the way upto Chengalpattu station due to space constraint at Chennai Egmore. if wisely plan they can consider extension upto Puducherry or upto Villupuram with stoppages at Tambaram,Chengalpattu, Melmaruvauthur, Tindivanam ( from Tindivanam station every 10 minutes there is bus available to Pondicherry (short route to Pondicherry by road ))if there is no any objection from the passengers.
