Answer:
About 55 minutes. The Panama Railway operates two passenger trains each day. The morning train goes from Panama City to Colon and the afternoon train goes from Colon to Panama City. These are really commuter trains serving the people who live in Panama City and who work at the Free Trade Zone in Colon. The trip takes less than an hour, about 50 minutes. It is a scenic ride as it takes you through the jungle, then along side the Panama Canal, and then back into the jungle.
