"Frank S"

In 1989 a cooperative venture between LGB and the master craftsmen at Aster, produced a steam-powered model locomotive - the 'Frank S'.  The locomotive features extensive detailing, heat resistant paintwork, full controls and fittings, etched data plates and is ready to be fitted with radio control. 

The prototype 'Frank S' was built by Henschel in 1941 for the Heeresfeldbahn and was found in a storage depot in 1945.  It was then put into service on the Juterbog - Luckenwalder Kreiskleinbahn as locomotive Number 1.  In 1949, the 'Frank S' was renumbered DB 99 4652 and continued to operate until 1965.  From 1966 to 1968, it saw service on the island of Ruegen, and in 1974, it was privately purchased, and today the renamed 'Nicki + Frank S' pulls special trains on the Jagstalbahn near Heilbronn / Stuttgart in Southern Germany.
