A third route of a bus service seen as a symbol of the India-Pakistan peace process held a trial run on Sunday.
The Amritsar-Lahore bus service reaches the Wagah border point
The bus left the Indian city of Amritsar and crossed the Wagah border point, heading for Lahore in Pakistan.
The trial run had been planned for October but was postponed in the wake of the deadly regional earthquake.
India and Pakistan restarted a Delhi to Lahore service in 2003 and a route across the disputed and divided region of Kashmir began in April this year.
India and Pakistan both claim Kashmir in its entirety and have fought two of their three wars since independence in 1947 over the region.
The bus diplomacy is one of the more tangible elements of the two-year peace process between the two nuclear-capable rivals, who nearly went to war over Kashmir in 2002.
Sunday's trial run carried seven officials and two drivers.
One of the drivers, Amreek Singh, said: "I am so happy that I cannot explain it to you."
The first full service is scheduled from Lahore on 23 December
The gold-coloured bus left Amritsar at 0900 local time and reached Wagah - the nations' only international land border - at 1040 before heading on to Lahore, a total journey of 60km (37 miles).
The bus was greeted by Pakistani transport officials who showered it with flowers.
Pakistan will carry out a reciprocal trial run this Tuesday.
If the trials are successful the full service is scheduled to begin on 23 December from Lahore and 27 December from Amritsar.
The Pakistan service leaves Lahore on Fridays and returns on Sundays, the Amritsar service leaves on Tuesdays and comes back on Wednesdays.
Indian Foreign Secretary Shyam Saran said on Saturday: "The limited kind of opening between India and Pakistan over the past two years has demonstrated that there is a huge pent-up demand for interaction and business development."
A fourth service, between Amritsar and the Sikh pilgrimage centre of Nankana Sahib in Pakistan, is also set to be launched this month.
Despite the increasing transport links, the two nations have still made little progress on a political solution for Kashmir.
The cross-Kashmir bus service was suspended indefinitely in the wake of the 8 October earthquake that killed more than 73,000 people.
