Important information about our services
For professional reasons, as Managing Director of RZTec, I am no longer able to produce signals, traffic lights or other illuminated items at present or in the longer term. I am therefore withdrawing from this area of signal, traffic light and level crossing construction.
In future, our store will only offer items that we can supply reliably. Signal orders that have already been placed will continue to be processed by my valued business partner, Mr. David-Konrad Fürstenberg from DF Modellbau. Please understand that the processing of these orders may be further delayed due to the current situation. If you have any questions in this regard, please contact fuerstenberg@rztec.de.
We thank you very much for your understanding and support. If you have any questions, please do not hesitate to contact us.
