Dear friends of the model railway,

The good news in advance: We were and are still available for you. Together with you, we have come through the corona pandemic well so far. We would like to thank you very much for that.

Surely you have learned through the media that there are major supply bottlenecks in many areas of electronics production. We are also not spared from this and occasionally have to wait a long time for some components, so that there are waiting times in the production of LDT decoders.

If, in view of these circumstances, there are delays in delivery, we will count on your understanding and patience.

The service hotline will continue to be available to you unchanged.

Take care of yourself, stay healthy!

Littfinski Daten Technik LDT arrived at our company

After more than 2 decades as a successful company in the model railway industry with more than 100 trade fair participations, Mr. Peter Littfinski decided at the beginning of 2019 to hand over the company and enjoy the well-deserved state of retirement. We, Bühler electronic GmbH, have decided to take over LDT's model railway activities because we appreciate Mr. Littfinski's robust and globally proven products.

In the two years since we took care of the production and sale of LDT articles, we have met many regular customers and have been able to win new customers. At this point we would like to thank all of you, our private and our commercial customers, for your patience, your understanding, the beautiful conversations and above all for the trust placed in us.

Through consistent optimization of processes and the automatic processing of your orders, we continue to work on improving our delivery performance.

We are looking forward to further successful cooperation.

Your Bühler electronic Team
