 Commuters had to exit one system, purchase a new ticket before entering the other system if they wanted to transfer from one line to the other.Prior to 2006 when a plaza was built above the Klang River linking the stations, Ampang Line and Sri Petaling Line's Masjid Jamek station and Kelana Jaya Line's Masjid Jamek station were two physically separate buildings.There were limited pedestrian walkways between the two stations resulting in commuters having to be exposed to the sun and rain, and even having to cross the busy Jalan Tun Perak, just to change from one line to the other.
