• This is no "all time roster"... only those locomotives which are still in existence or those which are mentionned in this folder are referenced here...
• Numbers are "DR 1970" style, 99 xxxx, because this is the numbering scheme that HSB is currently using...
• ... and I supply them w/o the "computer digit" but you may "compute" it easily... they use the standard UIC way to do this...
• Of course, french CFD Mallet "300" (Corse) and "400" (Vivarais) were never operated in the Harz but it is an intresting means of comparison:
  - a number of Vivarais Mallets are still in use...
  - but, sadly, all Corse Mallets were scrapped...
• The "Fairlie" was never operated on the Harz either, but it is currently stored at Ilfeld, near Nordhausen...
• About the valve gear... data are given using german style:
  - H.a. means "Heusinger-Steuerung aussen" (Heusinger valve gear, outside mount)
  - St.a. means "Stephenson-Steuerung aussen" (Stephenson valve gear, outside mount)
  - A.a. means "Allan-Steuerung aussen" (Allan valve gear, outside mount)
• Attn. US "visitors", all data are "metric"... and please remember that a "metric ton" is much heavier than a US ton: about 1.12; i.e. 10t (metric tons) axle load / as standard in the Harz / is equivalent to 11.2t (US tons)...
• If you want to know more about the locomotives, please help yourself and go to the files about each class... (if you arrived here... you probably know the way it works...).
• This applies to data related to s/n...
• A " - " means that this data does not apply; if there is... a blank... or a ? ... well... it means that I do not have the infomation... but if you have it, I will be happy to include it in the table...
• Most information in this document comes from...
  - "Taschenbuch Deutsche Schmalspur-Dampflokomotiven" (Franckh'sche Verlag)
  - old issues of "Der Modelleisenbahner" (TRANSPRESS), from old GDR,
  - data supplied by HSB,
  - data about the french Mallets come from old "FACS" magazines and MTVS magazine #4 / October 1977...
  - ... and others... (more about these books / magazines / etc... in the bibliography
• Display: unless it really agrees with "smaller-than-normal" size fonts, you will need to adjust your browser because the table below / if displayed using normal size font / probably is much wider than the standard display area !
• Printing: ... and probably you will need to adjust the "page layout" too... so that it prints OK !
• Other data files are available about...
  - the non-articulated / rigid frame steam locomotives of the Harz
  - the diesel locomotives of the Harz
  - the diesel railbuses of the Harz
