A money train is one or more railcars used to collect fare collection revenue from stations on a subway system and return it to a central location for processing. This train is typically used to carry money bags guarded by transit police to deter robberies.

Money Train is a 1995 American action film starring Wesley Snipes, Woody Harrelson and Jennifer Lopez as New York City transit cops and Robert Blake as their iron-fisted boss. After losing his job, Harrelson's character plots to hijack and then rob the "money train" which hauls collected fare revenues for the New York City Subway from the system's stations.
