The Jakarta Light Rail Transit (LRT) East-West Corridor is one of the corridors recommended for DKI Jakarta railroad network in 2019-2039. This corridor is planned to accommodate passengers commuting from Pulo Gebang to Joglo. The construction of this corridor is divided into two phases, the 1st phase (Pulo Gebang- Karet) is 20,6 km long while the 2nd phase (Karet-Joglo III) is 12,35 km long. In this Thesis, an elevated railroad will be designed specifically for the 1st phase consisting of 13 stations wherein 1 station is connected to the train depot (Dipo). The design is done by analyzing results from processing secondary data such as Google Earth maps/satellite imagery, passenger demands (from 2023 to 2063) and specifications of the operating LRT train. The analysis is then used for designing the railroad geometry, the railroad components, the operational of the train, and the station emplacement in accordance with available codes. The railway geometry design is bounded to Dipo-Buaran II segment with track length of 8.57 km, minimum radius of 200 m and track elevation between 17 m and 23 m. Furthermore, with expected train passing tonnage of 14,303,520 tons/year by 2063, the doubletrack railway with 1435 mm gauge is classified into Class II and therefore the type of rail used is R-60. The track structure type used is the direct fixation (“ballastless”) system which consist of welded rail joints, direct fixation fastener (specifically Pandrol E-Clip) and reinforced concrete plinth as its components. On the other hand, the operational design is done for the whole Phase I (Dipo-Karet). With predicted demand as high as 47,896 passengers/train/day in 2023, 8 trains with 2 cars/train will operate for 18 hours a day with 12.56 minutes of train headway. Finally, the emplacement at Karet Station simply consists of 2 tracks, a 105-meter long and 6.5-meter wide platform on each track, and W-12 crossover switches.
