Coins are the main currency of Pocket Trains, being used to buy new stations, licenses, and for repairing trains if they have a failure. Coins can be bought with Bux from the Bank, but the exchange rate fluctuates every day. For example, today's rate might be 1 Bux = 157 Coins, while tomorrow's rate might be 1 Bux = 450 Coins. Coins are also made through transporting jobs, or cars, to a destination using Trains. For some job values, see cars.
