ALATCO Philtranco traces its origins to July 1, 1914, when American soldier Albert Louise Ammen, together with Max Blouse founded the A.L. Ammen Transport Company (ALATCO), a small transportation company in
Iriga, Camarines Sur. The company began operations with an initial fleet of a single auto truck serving the Iriga-Naga route. In the succeeding years, ALATCO expanded its services across the provinces of
Camarines Sur,
Camarines Norte,
Albay and
Sorsogon, becoming a major transport operator in the Bicol region. The outbreak of
World War II in 1942 temporarily halted the company's expansion. Operations resumed in 1945, with the company using surplus
United States Navy trucks acquired through the United States Commercial Company. However, during the post-war period, the company faced intense competition and operational difficulties. In 1949, ownership of ALATCO was transferred to the heirs of Don Nicasio Tuazon in Manila, who infused new capital into the company and initiated a rehabilitation and expansion program that included the conversion of gasoline-powered engines to diesel engines. By 1952, ALATCO operated a fleet of approximately 400 units, with its main facilities being based in Irigas and subsidiary shops located across the provinces of
Daet and
Labo in Camarines Norte;
Naga, Camarines Sur;
Ligao,
Tabaco, and
Legaspi in Albay, and
Sorsogon and
Irosin in Sorsogon. The following year, the company expanded into Quezon province by consolidating several local bus operators under the Eastern Tayabas Bus Company (ETBCO), which later entered into a 5-year lease agreement with the Laguna Tayabas Bus Company.
PSEI In 1971, ALATCO and ETBCO were sold to the Mantrade Group of the Lopa and Cojuangco families. The two companies' operations were then merged and reorganized as Pantranco South Express, Inc. (PSEI), distinct from Pantranco North Express, Inc. Due to rising fuel costs and global economic conditions in the early 1970s, PSEI was strapped in debt and was subject to a
creditor takeover in 1973. This led to a corporate rehabilitation being implemented the following year, during which the company expanded inter-island operations through partnerships with passenger ferry operators serving
Catanduanes,
Samar, and
Masbate. PSEI introduced air-conditioned coaches on its southern routes in 1978 and expanded its freight services in 1980, relocating its central offices and terminal to its present site in
Pasay. In 1981, the company extended its network into
Eastern Visayas and entered sea transport operations, operating ferry services between Matnog, Sorsogon and Allen, Northern Samar. Further service upgrades followed in 1982 with the introduction of its higher-end Royal Class and new air-conditioned coaches with onboard toilets and
videocassette recorder entertainment systems. PSEI also became the first bus company in the Philippines to computerize its operations.
Philtranco In 1984, PSEI became part of a joint venture that formed the St. Bernard Services Corporation, which operated ferry services across the
San Bernardino Strait. In the same year, the company was renamed Philtranco Service Enterprises, Inc. In 1986, Philtranco launched its first integrated Luzon–Visayas–Mindanao
bus-and-ferry service, connecting Luzon with Visayas and Mindanao through intermodal transport routes. In April 1999, Philtranco was acquired by the Penta Pacific Realty Corporation led by businessman Jose C.H. Alvarez. The new ownership initiated a fleet replacement of 80 units costing PHP250 million. In June 2000, the company introduced its 29-seater
Gold Service Bus premium bus service, which featured airline-style passenger check-in and baggage tagging systems, the first in the Philippines to do so. By 2004, the company was considered as the only integrated land and sea transport company in the Philippines. That same year, in response to then-Philippine president
Gloria Macapagal Arroyo's push to modernize the country's land and sea transportation system, Philtranco announced a PHP4 billion (US$75 million) investment program to acquire new fleet of buses and ferry boats, and improve and expand its terminals. During the late 2000s and 2010s, Philtranco continued to introduce new bus models. It participated in the
Public Utility Vehicle Modernization Program, phasing out older units beginning in 2014. In 2016, Philtranco participated in a joint modernization initiative with the Archipelago Philippine Ferries Corporation and its affiliate Jam Liner, aimed at expanding integrated transport services nationwide. In 2025, Philtranco and its subsidiary Amihan Bus Lines temporarily suspended operations due to financial difficulties but later resumed services. In February 2026, the company announced plans to cease operations by March 30, 2026, citing sustained business losses that rendered continued operations unsustainable. However the management later clarified that it would temporarily suspend its operations. == Terminals ==
