Taiwan's railway history is compressed and eventful. The island's first railway opened in 1891, built during the Qing dynasty. The Japanese colonial period from 1895 brought systematic expansion: new trunk lines, mountain railways into the highlands, narrow-gauge networks serving the sugar industry. After 1945, the Republic of China government inherited the system and continued developing it through the postwar decades. The locomotives at the Miaoli Railway Museum span this history. The CT150-class steam engines date to the Japanese-era main line; the DT560-class were heavier freight haulers. Among the diesel collection, the R0-class diesel-electric locomotives — including R6 on display — were workhorses of the transition era when diesel began replacing steam across the network in the 1960s and 1970s. The narrow-gauge LDH101 diesel-hydraulic locomotives represent a different system entirely: the 762mm track that served the sugar plantations, a secondary railway world that ran parallel to the main network for most of the twentieth century.

What makes the Miaoli collection unusual is its range. Most railway museums settle into a single era or a single operator. Miaoli draws from several. The Taiwan Sugar Corporation number 331 tank locomotive represents the network of narrow-gauge sugar railways that once criss-crossed the western plains, moving raw cane from fields to mills. The Taiwan Alishan Railway Shay locomotive — number 28 — comes from an entirely different system: the steep-grade forest railway that climbs into the mountains of Chiayi County, a line so challenging that it required specially designed geared locomotives capable of ascending grades that would defeat conventional steam engines. Alongside these stand the Alishan diesel-mechanical locomotives (11403-1 and 11403-5), which replaced steam on the mountain line. The result is a collection that tells several overlapping stories simultaneously — mountain railway and plains railway, steam and diesel, standard gauge and narrow gauge, colonial-era and postwar.

The railway park adjacent to the existing museum had a difficult birth. Construction was completed on the NT$1 billion facility with an anticipated opening in 2023. Then, in September 2024, the original operator unexpectedly terminated its lease on the property, leaving the facility finished but without management. A new operator was selected in November 2024, and the park opened on April 25, 2025. Delays like this are not unusual in Taiwanese public cultural infrastructure, where the gap between construction completion and operational opening can stretch for years as governance questions are resolved. What waited inside the gates — an expanded locomotive display, railway-related artifacts, and the historic locomotive garage and turntable — justified the patience. The Miaoli Railway Museum proper, established in 1999, had been operating throughout, giving visitors access to the core collection while the larger park worked through its administrative complications.

The museum's location makes it an easy stop for anyone passing through Miaoli City on the Taiwan Railway. Miaoli Station sits a short walk to the north, which means the collection is accessible without a car — unusual for railway museums, which often end up at the edges of cities where land is cheap and connections are poor. Miaoli City itself is modest in scale, a county seat surrounded by the hills and agricultural land that characterize this part of central Taiwan. The railway that runs through it connects Taipei to the north and Taichung to the south, a route that has been in continuous operation for well over a century. The locomotives on display outside the museum are visible through the fence as trains pass on the active line nearby — a deliberate juxtaposition of the working present and the preserved past, the sound of modern rolling stock providing an unplanned soundtrack for the static machines in the park.
