Which of the following objects has more inertia than others?

Train

Inertia is the natural tendency of an object to resist a change in its state of motion or of rest. The mass of an object is a measure of its inertia.

A force that is just enough to cause a small cart to pick up a large velocity will produce a negligible change in the motion of a train.

Accordingly, we say that the train has more inertia than the cart and cycle.
