In December 1941 a group of Chinese railroad workers, led by the station porter Ma Yuan (Jackie Chan) engage in carefully staged raids of Japanese train shipments to disrupt Japan's military efforts to occupy China and invade other Asian nations to the south. When an injured soldier tells the group of a failed mission to blow up a strategically vital bridge, they take it upon themselves to complete the mission on the Chinese army's behalf.
Railroad Tigers is a hugely enjoyable slice of populist action-comedy, headlined by Jackie Chan in one of his most entertaining films in years. While the film has problems - in fact it has quite a few of them - none of them manage to fully obstruct what is ultimately a hell of a lot of fun. This is his third collaboration with director Ding Sheng, following Little Big Soldier in 2010 and Police Story 2013. To my mind this is the strongest of the three. It has plenty of action, a strong line in slapstick comedy, and makes the best use of its ageing star that I can remember.
