Here is a 50-100 word passage supporting the sentence:

The introduction of the DRG Class 99.19 narrow-gauge tank locomotive in 1938 marked a significant milestone in German railway history. Designed to navigate the winding tracks of rural East Prussia, these sturdy engines proved instrumental in transporting goods and passengers across the region. With their compact size and robust build, the Class 99.19 locomotives quickly became a familiar sight in the countryside, earning the nickname "Eisenbahnpferdchen" or "little iron horses" among locals. The success of this locomotive class paved the way for further innovations in narrow-gauge railway technology in the years to come.

 The outcome of the various experiments and modifications made to the A1s in the late 1920s was a new Class A3 " Super Pacific " , the first example of which was number 2743 Felstead . This locomotive appeared in August 1928 with 220 psi ( 1 @.@ 52 MPa ) boiler , 19 @-@ inch ( 483 mm ) cylinders , increased superheat , long @-@ travel valves , improved lubrication and modified weight distribution . Another new development was the changeover from right- to left @-@ hand drive , less convenient for a right @-@ handed fireman , but more so for sighting signals , resulting in the modification of all earlier locomotives .

 9900 and 9901 @-@ 9903 were articulated trainsets , with common trucks ( Jacobs bogies ) between each car . This caused operating problems , as train lengths could not be changed for demand and any single failure affected the entire train . All following power units were separate from their train , although four more articulated and semi @-@ articulated carsets were built .

 The class prototype was initially numbered 790 , with the rest following consecutively with a prefix " A " to denote a locomotive designed for the former SECR . The system of prefixes had been adopted by the SR to distinguish between locomotives with identical numbers acquired from different companies , and the K1 class became No . A890 when built in 1925 . This system was replaced from 1928 by a renumbering of all locomotives into one sequence , in which the K class rebuilds became Nos. 1790 – 1809 , and the K1 class rebuild became No. 1890 .

 El 18 is a modification of the Swiss Re 460 . The class was originally built in 119 units from 1992 to 1995 for the Swiss State Railways , where it was given the brand Lok 2000 . It was part of a project to create a series of new intercity locomotives and cars . Bern – Lötschberg – Simplon @-@ Bahn received eight units in 1994 ( as Re 465 ) , the Finnish State Railways received 46 units between the years 1995 @-@ 2003 ( as Sr2 ) and the Kowloon – Canton Railway Corporation received 2 units in 1997 . The units are designed to haul heavy passenger trains along existing curved railways at high speeds . It is designed as a universal locomotive , so it is also suitable for freight trains .
