Masjid Jamek LRT Station (GPS: 3.14968, 101.69646) is a major light rail transit station in Kuala Lumpur. Located at the junction of Jalan Tun Perak with Jalan Melaka, it is the interchange of two LRT lines - the above-ground Ampang Line and the underground Kelana Jaya Line. These two lines originally belonged to two different operators. As a result, the stations of these two lines are separated.
Commuters transferring from one line to the other have to get one of one station and enter the other. So, strictly speaking, the Masjid Jamek LRT Station is really two different stations that happen to be close together.
