battery operated trains are difficult to locate in the stores in the United States but not totally impossible to find. Adam wanted Murdoch very badly for Christmas so Santa found a TOMY Murdoch

The battery is simple to change by removing one screw from the top. Here are some picutures of where and how to replace the battery inside the coal car.
