As it says on the cover, this book is volume 2 - there appear to be three books in the series, from Studio Volker Schadach, book 1 is about the Harz network in general ("Schmalspurbahnen Im Harz") and book 3 is about the Selketalbahn ("Die Selketalbahn Im Harz"). All three are by the same author, Friedrich Metge. The odd thing is that of the copies I have, all purchased in one second-hand lot, volumes 1 and 2 have the bilingual German/English text, but my copy of volume 3 is all in German.
Anyone know if there is an alternative bilingual printing of vol.3? It's odd that the publisher would change that for the final volume.... the imprint details show that they were all published (or at least copyright dated) 1996/97.
Apologies for the slight thread hijack (though still talking about the books) - I figured that as Phil had already jumped in to buy then it a little bit of drift wouldn't be a problem....
