The Manila Railway Dagupan class comprised thirty side tank locomotives. They were built for the Manila Railway Company between 1888 and 1890, and were the first true mainline locomotives in service of the Ferrocarril de Manila a Dagupan inter-city rail line, succeeding two of five Manila-class light-duty locomotives. One of these locomotives, No. 17 Urdaneta, survives today on static display in an open-air museum in Dagupan, Pangasinan.

The Manila Railroad Company (MRR) was a Filipino state-owned enterprise responsible for the management and operation of rail transport in the island of Luzon. It was originally established by an Englishman named Edmund Sykes as the private Manila Railway Co., Ltd. on June 1, 1887. British engineer Horace L. Higgins was then assigned at the helm in Manila as its first general manager. On July 7, 1906, a separate private entity named the Manila Railroad Company of New Jersey was established. The two companies continued to own the Luzon railroad network until February 4, 1916 when the Insular Government acquired both companies and absorbed them into the new Manila Railroad.
