Bavarian D VIII : ウィキペディア英語版 | Bavarian D VIII
The Bavarian Class D VIII (''bayerische D VIII'') were saturated steam locomotives with the Royal Bavarian State Railways (''Königlich Bayerische Staatsbahn''). == History == In 1888, new locomotives were needed for the Freilassing–Berchtesgaden railway, which has inclines of up to 40 per mille (4%). Krauss initially delivered three machines, that were given the railway numbers 904, 905 and 906. The powerful boiler required a carrying axle that, based on a suggestion by Richard von Helmholtz, was designed as a trailing axle in the form of a Krauss-Helmholtz bogie. Thus equipped the locomotives had good riding qualities on the faster downhill run that was carried out backwards, while, for the slower uphill journey, it was sufficient to have the front coupled axle in the lead.
