Some of you may have seen the DHL farce I had in getting this collection that bolstered my existing few items. Anyway it safely arrived and the three locos dully tested performed well leading to the idea of a small setup to run them on.   Billerbahn was manufactured from the 50's to late 70's in Germany and they produced a range based on Feldbahn (field railway) or industrial stock. More info and catalogues can be found on this excellent site. http://www.billerbahn.de/Englisch/Listing-eng
