LATEST PRODUCT: BR 50 DB

The first DB loco from us is presented in the form of the BR 50. With all the differences from their DR counterparts present and correct, this pack provides a proper and accurate representation of these west German locomotives, as well as 2 scenarios for the Konstanz-Villingen route by Aerosoft (not included), and brand new appropriate rolling stock. With all of our usual advanced features (and more), and of course a simple mode for those who prefer it, this product is packed with realism. This is not simply a reskin of the Reko locomotives, but a brand new fully featured pack, and our best product of 2019!

NEXT RELEASE: BR 52.80 REKOLOK

Our next release will be DR's BR 52.80 Reko locomotives. The Altbau BR 52s will also come later this year.

REVIEW OF OUR BR 50.35 REKO:

"The locomotive is great! There are few high quality locomotives, especially German and then especially steam locomotives. The dynamic animations, like cylinder steam, blew me away. I look forward to other great locomotives!" 5/5
- train.tv (translated from German)

REVIEW OF OUR BR 41 REKO:

"Very nice steam locomotive. Great details and she is really fun driving." 5/5 - Gainmaster

REVIEW OF OUR V10C 0-6-0DM:

"An absolutely fantastic release yet again! Very realistic and there has clearly been a lot of effort and hard work gone into this. I thoroughly recommend this to any narrow gauge enthusiast!" - Matthew Beard
