The Pasig Line is a defunct Tramline of the Manila Electric Railroad and Light Company.
The Pasig line was originally operated by the Manila Suburban Railways Company until it merged with the Manila Electric Railroad & Light Company (Meralco) in 1919.
The Pasig line branches off from the Santa Ana Line, known as the Santa Ana Junction.
The remaining mountain side over the Kalayaan Avenue corner C5 road was the former right of way, beside the Upper Plaza today, the Napinday Floodway was the former bridge.
The construction of the floodway further increased the width of the Pasig River were the bridge passes by compared to old map
The construction of the Pasig line gave contributions and improvement to the areas passing it;
The transportation to and from the Rizal Provincial Capitol when the then municipalities of Pasig and San Pedro Macati were still under the province of Rizal.
It also passed at Fort McKinley (now Bonifacio Global City), the shipping of armor supplies to the camp was improved, the station is located in what is called Gate 1 today.
The end of the Pasig line is often mistaken as Brgy. San Joaquin although not even one map between 1908 to 1945 can prove that, as it always makes a curve before reaching Buting and bypassing it.
The end of the Pasig line is the Pasig station of the Manila Railroad Company (PNR today), passengers can transfer there and take another train either bound for Antipolo or Montalban, the location of the station wa the present day Pasig Rotonda.
Aside from congested roads, another factor on why the Pasig line is impossible to be revive is the Bel-Air Subdivision which is built on its fomer right of way, it is located between Poblacion and Pinagkaisahan in Makati.
After the line was abandoned, the section from Santa Ana, Manila to Fort Bonifacio was converted into a road and named Pasig line, the Makati section was later renamed Kalayaan Ave.
Although a tramline often have its tracks in the center of a road, some sections of the Pasig line have its own right of way.
