Featured Locomotive for March 2013

Der Adler

This month we will review 'Der Adler'-the Adler,the Eagle, which was Germany's first commercial locomotive. There had been numerous attempts before Adler as early as 1816. The Bavarians were very thorough in their search for a loco -R Stephenson, Braithwaite and Erisson. The loco had to pull 10 tonnes and cover the trip from Nuremberg to Furth in 8 to 10 minutes, carriages to be heated with charcoal. Stephenson replied that he could supply a loco the same as the Liverpool and Manchester Railway of 7.5/8 tons. A lighter engine would not have the adhesion and he quoted 1800 pounds sterling. Holmes and Rolanisons were late starters but failed to gain acceptance as were a number of others. Financers Planter and Manberger went to Brussels and stayed at the same guesthouse as Stephenson. On 3rd may a letter of intent was signed for Stephenson to supply a six wheel loco 2-2-2 at a cost of 750-800 poinds sterling - eventually 900 pounds. Adler was built by Robert Stephenson in 1835 and had its first run on 7th December 1835.

The Englist foot and the Bavarian foot were different and as the loco was 4ft 8.5ins (1435mm) the Bavarian track had to be re-laid and widened by 5/8 in. Coal at that time was very expensice so the sheaper coke was used to haul the 200 passengers, by 1845 goods were dominant with mainly beer, barrels and cattle. By 1857 Adler was the weakest loco in Europe. Adler was scrapped in 1858.

Many replicas have been made of Adler, 1935, 1950, 1984 and reconstructed 2008, to which we can add Markin's 1 Gauge loco in the same year. Reportedly this was the last Markin special model before the banks moved in and stopped production
