Step 1: Locate the range "120-139" on the x-axis (Number of passengers).
Step 2: Find the bar corresponding to this range.
Step 3: Read the height of this bar on the y-axis (Number of trains). The top of the bar aligns with the value 20 on the y-axis.
Therefore, 20 trains had between 120 and 139 passengers.
The number of trains is $\boxed{\text{20}}$.
