To find the length of the faster train, we can use the relative speed concept.

The relative speed between the two trains is the difference of their speeds:

Relative speed = Speed of express train - Speed of local train

Relative speed = 65 km/h - 29 km/h = 36 km/h

We need to convert the relative speed from km/h to m/s since the time given is in seconds.

1 km/h = (5/18) m/s

Relative speed = 36 km/h * (5/18) m/s = 10 m/s

We are given that it took 16 seconds for the faster train to pass the driver of the local train. The time it takes for the train to pass is the same as the time it takes for the train to cover its own length.

Distance = Speed * Time

Length of faster train = Relative speed * Time

Length of faster train = 10 m/s * 16 s = 160 meters

Therefore, the length of the faster train is 160 meters.
