There are two exits from the railway station. One is the main exit that is on Pf 1 and another one is by the FOB which connects Pf 1 to 6 open up outside the Pf 6. But this side is bit dirty and risky to go in night time. Pf 6 side open up on the road which caters the maximum of transport companies and also the regional office of SAI (Sports Authority of India) on this road. Even though this road connects quickly with the hall gate but if new to amritsar and with family, then opt the main exit only.
The main exit on Pf 1 opens up to the vibrant GT road. If with luggage, then take auto/cab...

Near the railway station this GT road becomes very narrow and crowder) and ask for any share autos or buses. Buses (both Govt and Private) regularly ply. Share autos very easy available to Putlighar, Chherta, Khasa side. Free Darbaar sahib bus ply daily from station to darbaar sahib. If you have to go new cantonment area, then take share auto to khasa. If Old army cantonment area, then take share auto till putlighar and alight at putlighar. Its walking distance from Putlighar.
