Prophetic Symbolism of Transportation.
Vehicles (bikes, boats, aircraft, trains, buses etc.) usually symbolize ministry of some kind, life journey or means of reaching a destiny. The speed is also important because it defines time of getting from departure (as in right now) to the arrival (when God brings the fulfilment). Colour of the vehicle, as well may be important. For example, a brown vehicle or green vehicle. See the colour section.
Subway: underground, unseen, sometimes it may surface for a bit then go down again, behind the scenes, hidden.
Train: a train sometimes represents training (play on words) but most forms of transportation represent ministry.
Air plane: higher spiritual elevation, rising up higher, higher level ministry OR things you are going to do in the Spirit, although rising on an eagle is a more common image for this.
Old car: older form of ministry, could even be old wine skin.
New car: could be faster, slicker (positive or negative,) cutting edge, more efficient and effective.
Truck: used for hauling things to different locations, bringing supplies back & forth.
Ocean liners: large influences over people, ministry with a large influence. The ocean represents people and nations.
