If you have an old QSI equipped loco that we produced from 2001~2007, please note that we no longer accept those for repair or provide support for them. However, Train Service Depot may be able to help if the problem is purely electrical. Also, if you would like to have the electronics in your model upgraded, TSD can help with that!
