Emily, Customer ServiceWe're sorry to hear that you were disappointed in this train. While we don't make a rechargeable battery pack for it, rechargeable batteries will work A-Okay. As for the clicking, we'd first recommend double-checking that nothing's caught in the wheels (dust, hair, etc.) If they're all clear and the train's still making noise, please get in touch at LEGO.build/Service-BV.
