Railroad Man

A signalman at a remote train station in the heartland of Japan receives news that the job he has laboured at all his life is coming to an end as the train company have decided his station is uneconomic and are set to close it soon. Facing an uncertain future and recently widowed, the signalman takes solace from the past; the past that he increasingly comes to realise was laden with the wrong priorities.
