The Marikina Auto Line Transport Corporation (MALTC) buses is the only one that regularly travels to farther places like Makati and Parañaque. UV Express vehicles ply the routes to Cubao in Quezon City and Santa Lucia Grand Mall in Cainta. Formerly, there was railway service under the Manila Railroad Company that traversed the San Mateo, Marikina, and Pasig areas and had its terminus at Barangay Balitè behind the Santo Rosario Parish Church but it had been long dismantled and the railway line converted into roadway that now consists of the road aptly named Daang Bakal. It is known that 'patok' jeepneys originated from this town way back during the 1980's. These jeepneys are known for their notoriety on the road. Despite this, they are popular among the passengers hence the name patók which means 'popular'. They still ply this town up to this day, most plying the Montalban-Cubao route via Marcos Highway. These jeepneys have already spread throughout the Rizal province as well as in Marikina since then. List of local chief executives Hospitals H Vill Hospital N.
