yes.

in running the train, some power is still needed to propel the train forwards. Although some of this can be regained by regenerative braking, there will inevitably be some loss. Unless the train is fully powered on renewables, there will still be pollution as a result of running the train.

Even if the train is powered on renewablesand generates no pollution in running, the energy and resources to build the train (not to mention tracks etc) have to come from somewhere, most likely with resultant atmospheric pollution.
