A train is a railroad engine connected to cars for carrying people or to wheeled containers for carrying goods. Dreaming of being on a train could represent being continuous in ministry or in your personal life.
Positive: Dreaming of being on a train could also signify being spiritually or naturally connected. It could symbolize rapid progression in ministry work for the Kingdom of God.

Negative: Dreaming of being on a train could represent hastiness or not paying attention to your surroundings.

Wisdom: God could be showing you that you are moving from place to a place in ministry and reaching more souls. It could also mean you are growing and maturing in your spiritual life with the Lord and He is accelerating you in ministry. Pay attention to what is happening in the dream because those details can give you a better indication of where God wants to take you and what He wants to show you. It is important to consider all the details of your dream and understand what is being said and also what is not. If the areas seem dangerous that you are traveling to, you should pray and ask God to prepare you to be able to stand and fulfill all His will and work for where He sends you without fear or compromise.
(Acts 2:42).
