Roechling Iron & Steel 0-4-0 Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class 20 (Locobase 5104)

Two veterans of this this Saarland steel company. See [] (August 2002) for data -- supplied by Rainer Veauthier -- and history. 20 (works #5143) was delivered on 7 May 1904; 21 (#5168) followed on 28 May.

After a new steel works was completed in the mid-1980s the old mill in Voelklinger were closed down. In 1999, the site, which had been designated a UNESCO cultural heritage location, was reopened.


Class 46 (Locobase 5103)

A relatively large and certainly late-in-the-day industrial locomotive supplied to this Saarland steel company. See [] (August 2002) for data -- supplied by Rainer Veauthier -- and history. The locomotive spent its 18-year career shuttling pig iron from the blast furnaces to the steel mills.

After a new steel works was completed in the mid-1980s the old mill in Voelklinger were closed down. In 1999, the site, which had been designated a UNESCO cultural heritage location, was reopened and this locomotive was moved there.
