direct transfers were removed, meaning passengers traveling on the line can only connect to other lines by walking a short distance to nearby stations. Additionally, several stations in Zone 1 were closed, while Santa Cecilia station was added. Branches Stations Line 13 (Corredor Central) The second line to be opened, Corridor Central or Eje Central, runs through zones 4, 9, and 13 of Guatemala City. The buses are similar to the ones on Line 12, except for the Bi-articulated buses. The change in bus types was done to allow the line to travel through the historic centre as the streets are narrower compared to those of the CA1. Another interesting difference between Line 12 and Line 13 is that, when Line 13 was still a proposal, the developer promised to revitalize the areas where the Line would eventually operate. This revitalization included new monuments, better sidewalks, improvement of street vendor spaces, and others. Line 13 connects with Line 12 at "Plaza Barrios" and "El Calvario", creating seamless connections to the downtown and the southern areas of the city. Stations on this line are equipped with accessibility features such as braille that tells users the name of the stations and the connecting lines. This line, as mentioned earlier, runs through the historic downtown, this means that during its journey it will pass by popular landmarks of the city such as the Torre del Reformador, the Acueducto de Pinula, the Bank of Guatemala, Civic Centre, and 6th Avenue, a popular pedestrian-only section of the city. The line was certified as "Silver" under the BRT Standards in 2014. In the 2023 service update, Line 13 had its termini changed to Tipografia in the north and Hangares in the south after a number of stations closed, south of Plaza Argentina. Fuerza Aerea station was opened and all direct transfers were removed. Branches Stations Line 1 (Centro Historico) Line 1 works in mainly in Zone 1 of Guatemala's Downtown. This line was built soon after Line 13 began operations. The main goal of this line was to make the historic centre more accessible through safe and reliable public transportation. This line travels from 3rd Street in Zone 1, towards 18th Street in Zone 1, passing through 5th Street and 8th Street. This line started service on December 19, 2012. In the 2023 service update, its southern terminus was changed from Tipografia Station to Centro Civico,
