Yes! Many parts for trains made throughout Lionel's history are still available. Reproductions of difficult to find parts are also available. Lionel still maintains Authorized Service Stations with trained specialists who can not only repair current production, but also older Lionel products. You can check for a local Service Station at Lionel's website - www.Lionel.com under the customer service tab. You might also check local hobby shops. The service manual can help you identify parts which can then be purchased. For more current production, Lionel offers instruction manuals and exploded parts diagrams which are viewable on their website www.lionel.com.
