Using Fast Tracks tools and supplies, building curved trackwork is no different from building straight trackwork and does not require any special skills. The only real difference is that the rail needs to be pre-curved. To ensure that the rail is properly pre-bent, we highly recommend you consider including a Fast Tracks Rail Roller with your order. The Rail Roller tool will make it easy to create smooth, consistent curves and ensure that the rail is properly pre-bent to retain its shape over time.
