Zhongli is on the Taiwan Railways western trunk line, with local and express trains from Taipei every few minutes. Local trains take about 45 minutes; the Tze-Chiang express is around 30. The MRT-Taoyuan Airport line also stops at Zhongli (the station is called A22 Zhongli, opened in 2024 as the final extension), giving direct access to Taoyuan International Airport in about 30 minutes.
Frequent inter-city buses run from Taipei Bus Station and from Taoyuan to Zhongli's main bus terminal opposite the railway station. From Zhongli itself, local buses cover Pingzhen, Longgang, and the surrounding districts. Taxis are inexpensive and Uber operates.
